Chez Forever Institut, nous pratiquons la médecine esthétique régénérative depuis plus de 25 ans. Voici ce que nos médecins observent en consultation.

Régénération cutanée : le principe commun

Avant d’entrer dans les différences, il faut poser une base. PRP et exosomes appartiennent tous deux à la médecine régénérative, c’est-à-dire qu’ils visent à stimuler les mécanismes naturels de réparation de la peau.

Le PRP : les facteurs de croissance de votre propre sang

Le PRP, ou Plasma Riche en Plaquettes, est fabriqué à partir d’un prélèvement sanguin réalisé le jour même de la séance. Ce sang est centrifugé pour isoler le plasma concentré en plaquettes, qui contient une grande quantité de facteurs de croissance : PDGF, TGF-β, VEGF, entre autres. Ce concentré est ensuite réinjecté dans les zones à traiter : le visage, le cuir chevelu, le décolleté.

L’action du PRP est progressive et cumulative. Les plaquettes libèrent leurs facteurs de croissance sur plusieurs jours, ce qui stimule la production de collagène, améliore la vascularisation locale et accélère la réparation tissulaire. Le résultat visible demande généralement 4 à 6 semaines et se construit sur un protocole de 3 séances espacées d’un mois.

Un avantage que nos médecins apprécient particulièrement : le PRP est autologue. Il est préparé à partir du sang du patient lui-même, ce qui rend les réactions d’intolérance rares.

« Le PRP fonctionne très bien sur les peaux fatiguées, les pertes de densité débutantes et les cuirs chevelus fragilisés. C’est un traitement que nous pratiquons depuis de nombreuses années à Forever Institut — les résultats sont réguliers et bien documentés. » — Dr Luigi L. Polla

Les exosomes : la signalisation cellulaire de nouvelle génération

The exosomes sont des vésicules extracellulaires nanométriques, des petites capsules libérées naturellement par les cellules pour communiquer entre elles. En médecine esthétique, on utilise des exosomes issus de cellules souches d’origine végétale, purifiés et concentrés, que l’on applique sur la peau.

Leur mode d’action est différent du PRP : les exosomes ne contiennent pas de cellules vivantes, mais transportent des ARN messagers, des protéines de signalisation et des microARN qui influencent directement le comportement des cellules de la peau. En termes simples, ils donnent des instructions : produire plus de collagène, réduire l’inflammation, accélérer la cicatrisation.

En pratique, les exosomes s’utilisent en application topique intensive après des traitements ablatifs (laser fractionné, microneedling, peeling profond). Leur capacité à pénétrer en profondeur et à potentialiser les effets d’autres traitements est ce qui les distingue le plus nettement du PRP.

C’est aussi un domaine où la recherche avance vite. Les protocoles se précisent, les concentrations s’affinent, et les preuves cliniques s’accumulent, même si, sur le marché suisse, la réglementation Swissmedic encadre strictement les produits utilisables en pratique médicale.

Ce qui les distingue vraiment

La question n’est pas de savoir lequel est « meilleur ». Ce sont deux outils avec des usages différents, complémentaires dans certaines situations, interchangeables dans d’autres.

Le PRP est préférable quand :

• Le patient présente une perte de fermeté progressive et une peau terne
• La revitalisation du cuir chevelu (alopécie diffuse, fragilisation)
• Le profil immunitaire ou la préférence pour un traitement autologue 
• Le budget est défini et le patient souhaite un protocole connu, à résultats prévisibles

Les exosomes sont plus adaptés quand :

• Le traitement est combiné à un laser, un microneedling ou un peeling profond, les exosomes amplifient la cicatrisation et le résultat
• La peau est sèche, réactive ou présente des signes d’inflammation chronique
• Le patient souhaite une récupération accélérée après un traitement ablatif
• L’objectif est une amélioration de texture et d’éclat

« Dans notre pratique, les exosomes et le PRP ne s’opposent pas, ils se positionnent. Le PRP reste notre référence pour la revitalisation globale et la perte de densité. Les exosomes entrent en jeu dès qu’il y a un traitement laser associé ou une peau particulièrement fragilisée. » — Dr Luigi L. Polla

Ce que recommandent les médecins de Forever Institut

La consultation médicale préalable est recommandée. C’est elle qui permet de déterminer lequel de ces deux traitements (ou leur combinaison séquentielle) correspond à l’état réel de la peau, aux objectifs du patient et aux traitements déjà réalisés.

Chez Forever Institut, chaque protocole régénératif est défini sur mesure. Nos médecins évaluent la qualité cutanée, l’historique des traitements, les attentes et le contexte général de santé avant toute recommandation.

This volume of cases has taught us what clinical studies don't always tell us: why some patients achieve spectacular results, why others are disappointed, and how to guide therapeutic decisions with honesty.

This article is medical feedback, not a commercial promise.

How does cryolipolysis work in practice?

CoolSculpting® is a non-invasive procedure that breaks down fat cells located directly under the skin by administering controlled cooling to the skin surface. The destroyed fat cells are then naturally assimilated by the body over a period of several months.

Visible results appear on average one month after the session. The definitive result takes six months. This is a point that we systematically explain to our patients, as many expect to see a rapid transformation. Cryolipolysis doesn't work like that. It's a slow, biological reduction that takes place over time.

In practice, one session produces a reduction of around 30 % in the volume of fat in the treated area. If the bulge is more than 3 cm thick, we plan two sessions spaced two months apart to achieve sufficient results.

The treatment does not replace conventional methods such as diet, exercise or liposuction. It is a complement for resistant localised areas, not a global weight loss solution.

Situations where cryolipolysis gives the best results

After 25 years of practice, we have identified an ideal candidate profile: a person with one or two localised bulges, resistant to sport and diet, on an overall stable body. The best documented areas are the abdomen, flanks, thighs, arms, submental and submandibular region, back, subgluteal folds, arms and bra area.

This treatment is not suitable for overall weight loss. That is not its role. Patients who arrive with a targeted figure and realistic expectations are the ones who leave satisfied. Those who hope for a spectacular all-round effect are invariably disappointed.

What we have learned about side effects

Transient side effects are frequent and expected. They occur in the treatment area during the session and in the days that follow.

During the session: sensation of pressure, tightness, intense cold, tingling, cramp - these sensations diminish as the area becomes numb. Immediately afterwards: redness, stiffness, temporary whitening. Over the following one to two weeks: bruising, swelling, itching, numbness that may last several weeks.

Two rare effects deserve particular attention.

L’paradoxical adipose hyperplasia is manifested by an increase in the volume of fat in the treated area, visible between 2 and 5 months after treatment. Its frequency is estimated at around 1 in 3,000 treatments (0.033 %). When it occurs, surgery - liposuction - may be necessary.

La demarcation of the treatment area (approximately 1 treatment in 20,000, i.e. 0.005 %) corresponds to a visible depression in the treated area, the result of excessive localised fat removal.

Very rare effects have also been documented: frostbite (1 in 15,000), hyperpigmentation (1 in 11,000), vagal symptoms such as dizziness or fainting (1 in 30,000), cold panniculitis (1 in 60,000). These data are taken from the CoolSculpting® safety form (Allergan Aesthetics, CH-CSC-210028, November 2021).

These risks are documented in the informed consent form signed by each Forever Institut patient. This is not an administrative formality: it is a guarantee that the decision has been taken with full knowledge of the facts.

Contraindications that we strictly apply

The safety of the treatment depends on a rigorous assessment before each session. Certain situations constitute absolute contraindications: the treatment must not be carried out.

Other situations do not constitute absolute contraindications, but require a thorough medical assessment before proceeding with treatment:

• Known sensitivity to cold: cold urticaria, Raynaud's disease, frostbite or frostbite
• Reduced peripheral blood circulation in the area to be treated
• Neuralgic pain: post-herpetic neuralgia, diabetic neuropathy
• Bleeding diseases or taking anticoagulants
• Recent surgery or scar tissue in the area to be treated
• Hernia in or near the treatment area
• Active skin disorders: eczema, dermatitis, rashes on the skin area
• Implantable medical devices in use (pacemakers, defibrillators)
• Pregnancy, breast-feeding (no studies available)
• Chronic pain, anxiety disorders

These points are systematically checked during the initial consultation. We sometimes postpone or cancel a planned treatment if a patient informs us of a new pregnancy, an infection or taking anticoagulant medication the day before the session. Safety comes before planning.

Why do results vary from one patient to another?

This is the question we hear most often after a treatment. Two patients, same apparent morphology, same area treated: one is delighted, the other expected more. There are many reasons for this.

Firstly, the composition of the bulge. Some bulges contain more fibrous tissue than pure adipocytes, which reduces the response to cold. Lifestyle also plays a direct role: the effects observed persist over time only if the patient maintains a balanced diet and regular physical activity. Otherwise, the remaining fat cells can compensate for the loss of destroyed cells.

Cryolipolysis reduces the number of adipocytes in a given area. It does not alter overall metabolism or eating habits. This point, repeated at each follow-up consultation, is the key to lasting satisfaction.

Our medical view of growing demand

In the space of just a few years, cryolipolysis has gone from being a confidential treatment to a common request, fuelled by social networks and sometimes misleading before-and-after images. We are seeing an increase in misdirected requests: patients who wish to treat unsuitable areas, or who downplay the medical information needed to speed up treatment.

Our position has not changed since 1997: we only accept treatment when it is medically justified and clinically appropriate for the patient. Not to fill a diary, nor to follow a trend. The results we achieve over the long term are the direct consequence of this rigour.

Dr Polla's view

Founder of Forever Institut in 1997 and dermatologist specialising in laser medicine, Dr Luigi L. Polla has been practising cryolipolysis since its introduction in Switzerland. His view of this treatment, beyond the protocols :

Behind this visibility lies a real technology: the photobiomodulation, Its clinical effects have been documented since the 1990s. But the difference between a device selling for CHF 60 online and a LED treatment performed under medical supervision, the resemblance ends with the shape of the mask. This guide explains why.

What LED therapy really is

Photobiomodulation (or LED light therapy) is based on a simple principle: certain wavelengths of light penetrate skin tissue and trigger targeted biological reactions. Red light (630-670 nm) stimulates collagen production and accelerates cell healing. Blue light (415-430 nm) acts on the bacteria responsible for acne by disrupting their metabolism. Infrared light (760-850 nm) penetrates deeper to reduce inflammation and promote tissue regeneration.

These effects are real. They are documented in the medical literature, reproduced in controlled studies, and have been used for years in dermatology and aesthetic medicine protocols. So the question is not «Does LED work?» but «Under what conditions does it really work?»

Why does power change everything?

A consumer LED light is subject to strict safety standards that limit its irradiance - i.e. the density of power emitted per square centimetre of skin. These limits exist so that anyone can use the device at home without risk, without prior assessment, without a health professional nearby. This is a legitimate protection strategy. But it has a direct cost in terms of effectiveness.

Medical equipment used in institutes is not subject to the same restrictions. Their irradiance can be adjusted according to phototype, the area treated and the clinical indication. The «dose» of light delivered (measured in joules per square centimetre) is calculated to be therapeutically active, not simply harmless.

In concrete terms: a consumer mask typically delivers between 10 and 30 mW/cm². A medical device can deliver between 100 and 200 mW/cm², or even more depending on the protocol. For the same length of session, the energy received by the skin is not comparable.

«The advice of the Forever Institut Clinic»

«Below a certain irradiance threshold, the biological cascade we're trying to trigger simply doesn't happen. It's not that it's less intense, it just doesn't happen. It's the difference between an effective stimulus and a sub-liminal stimulus. At Forever Institut, we work with power densities calibrated for each indication: radiance, post-treatment healing, inflammatory acne».»

- Rachel Polla, CEO

Wavelengths: precision vs. approximation

A good quality LED mask will display its wavelengths on the product sheet. A cheap LED mask will also display its wavelengths, but the accuracy of the actual emission may vary by 20 to 40 nm from the advertised value. For anti-acne blue light, a deviation of 30 nm is enough to take you outside the bactericidal action window. For red light, inaccuracy reduces the depth of penetration and the activation of fibroblasts.

Medical devices use calibrated diodes whose spectral emissions are verified. At Forever Institut, the wavelengths used correspond exactly to the parameters of validated clinical protocols.

Medical supervision: what the device does not replace

An LED mask used at home is applied blindly. Even with good intentions, you don't know whether your skin has a temporary contraindication (recent tan, active inflammation, photosensitising treatment), whether the wavelength chosen corresponds to your actual indication, and whether the exposure time is adapted to your phototype.

During a consultation at Forever Institut, the LED protocol is defined after a skin analysis. The choice of wavelength, power, duration and frequency of sessions are adjusted according to your clinical situation. LED is often combined with other treatments - peeling, mesotherapy, Red light after a peel, for example, significantly accelerates recovery and enhances the effects of the treatment.

It is this coordination that explains the difference in results, much more than the question of power alone.

What the consumer mask can offer and its real limitations

Let's be frank: a consumer LED mask is not without effect. On healthy skin with a compatible phototype and with regular use, the red light can improve radiance, slightly reduce signs of fatigue and support the skin barrier. For someone who doesn't have regular access to a medical institute, it's a maintenance supplement that has its place.

But it does not treat. It does not correct severe acne-prone skin. It does not stimulate deep collagen synthesis. It does not replace a post-procedure protocol. And for darker phototypes (V and VI), some consumer devices present risks of irritation if the blue wavelength is incorrectly calibrated.

The main limit is not technological, but biological: below a certain irradiance threshold, the cellular response is not activated. You can use your mask every day for three months and still remain below this threshold.

What choosing means in concrete terms

If you're looking to maintain the radiance of your skin on a daily basis and you have fair phototype skin with no particular indications, a reliable consumer device (Currentbody, Omnilux, Déesse Pro) can complete your routine.

If you want to treat a specific indication - inflammatory acne, skin slackening, preparation or recovery after an aesthetic treatment - medical LED treatment is the only option that delivers a therapeutically effective intensity under appropriate supervision. This is the position of the doctors at Forever Institut, based on 30 years of clinical practice in aesthetic medicine in Geneva and French-speaking Switzerland.

During your initial consultation, our specialists assess your skin, your goals and your treatment pathway to integrate LED where it is really useful in your protocol - not as an accessory treatment, but as a precision tool.

Soft lines, circular lighting, calibrated silence: here, time sits still. Forever Institut

In Geneva, some institutions don't move - they move like an idea evolves: seamlessly, but with greater precision. Like Forever Institut, which is moving from the Rue du Rhône to the Rue du Commerce, just a few metres away... but with the ambition of taking much more than a few steps. A discreet, almost surgical shift. A slip of surface, a leap of depth. A controlled change, a calibrated beauty.

One might have expected a simple property facelift. But here, the gesture is more subtle. Forever Institut doesn't change the skin, it improves its texture. Since 1997, under the leadership of Dr Luigi L. Polla, the clinic has been refining its procedures and building up its expertise - pioneering lasers, long-term aesthetic medicine and an obsession with controlled naturalness.

Serums lined up, textures on display: beauty is chosen like a language here! Forever Institut

Today, the new space at Rue du Commerce 3 promises more light, more fluidity and more comfort. In short: less clinic, more experience!

Laser, scalpel, strategy: precision as religion
There are no vague promises or storytelling glows here. Forever Institut plays the serious card. With over 30 laser technologies and a 360° medical approach, the institute boasts surgical expertise in detail: dermatology, aesthetic medicine and surgery.

Surgical minimalism, a wide-eyed look: here, we treat without overdoing it. Forever Institut

PRP, PRF, Nanofat... words that sound like formulas, but which above all reflect an obsession: to regenerate rather than transform. And that's where the positioning is intriguing. At a time when aesthetic medicine is flirting with the spectacular, Forever remains on the side of control, measurement and sustainability. Less «wow», more «just».

Polla family: inheritance by slow injection
In a sector where brands are born and disappear at the speed of an Instagram filter, Forever Institut boasts a rarity: continuity. Here, we don't scale - we settle. This stability allows us to do one precious thing: take the time to test, to evaluate, and also to refuse.

At the heart of Forever Institut lies a family history that is passed on, embodied and refined, generation after generation, with the same obsession: to do the right thing. From left to right: Roxane, Rachel, Dr Luigi Polla, Cyrille and Ada © Forever Institut

Every technology is scrutinised before being adopted. A slowness that is accepted, almost militant. In a world obsessed with the new, Forever bets on the reliable. And that, in itself, is radical.

SIP glow bar: a shot of skin, a shot of glow
And then there's SIP. Three letters that click like a shot... but for the skin! Forever Institut's new Glow Bar distils a skin version of café serré: fast, targeted, terribly effective! Twenty minutes in no time to get your complexion back on its feet! Settle in, isolate yourself and almost disappear. Under the MyLED mask, the light works in silence: it stimulates, it wakes up, it revives the cellular mechanics without making a ripple. No noise, no frills - just skin that's back in action, as if it's finally asleep.

Under LEDs, time suspends its breath, while the skin rekindles the light. Here, radiance is drunk as much as experienced © Forever Institut

And while the face recharges, the body follows suit. With a NutriGlow Juice in hand, vitamins and radiance take over: inside, it's flowing, outside, it's glowing. The result? The complexion speaks again, the features relax and the mirror suddenly becomes more accommodating. A high-tech version of skin espresso. A shot of light, and the skin lights up the room again.

Skin, patience and precision
The aesthetic medicine market is exploding. Growing demand, a quest for naturalness, an obsession with “ageing better” rather than “not ageing”. Forever Institut didn't wait for the trend - it anticipated it. But where others focus on immediate glow, Forever goes deeper: skin quality, regeneration and facial coherence over time. A discreet, almost silent luxury.

Conclusion? Forever Institut is not out to impress. The clinic adjusts, corrects and perfects. In this way, its move is just like its treatments: precise, measured, almost invisible but profoundly effective!

In Geneva, where everything moves fast but nothing should be visible, Forever remains true to a simple idea: The best transformation is the one that can't be dated!

You're thinking of having a tattoo removed, and you want to know how many sessions you'll need before your skin is clear. This is the first question asked by the vast majority of people who come to Forever Institut for a tattoo removal. laser tattoo removal and that's a legitimate question, because the answer is never the same from one case to the next.

Laser technology has advanced considerably in recent years. Today, the latest generation of medical lasers can remove tattoos with a precision and effectiveness that older techniques could not achieve. But the number of sessions required depends on a number of clearly identified factors: the colour of the ink, the size of the tattoo, how long it has been there, the density of the ink and your skin type.

In this article, we detail each of these criteria to help you understand what determines the duration of your protocol and what you can reasonably expect from the first sessions.

How does a laser remove a tattoo?

The principle is based on the selectivity of laser light. The beam emits very short, very powerful pulses that target the ink particles encysted in the dermis. Under the effect of heat, these particles fragment into micro-particles that the immune system can then eliminate naturally.

Each session reduces the concentration of ink in the skin. The discolouration is progressive: the tattoo fades with each session, until it disappears or becomes imperceptible. The interval between two sessions - generally six to eight weeks - gives the body time to evacuate the ink fragments and the skin time to regenerate.

The opinion of Dr Luigi L.Polla«The response to laser treatment depends as much on the skin as on the ink. A tattoo made with professional quality ink and several colours will require a longer protocol than a monochrome tattoo with black ink. During the initial consultation, we assess these parameters precisely in order to establish a realistic estimate of the number of sessions required». - Dr. Luigi L. Polla

How many sessions on average?

The usual range is between 5 and 15 sessions, depending on the case. According to the doctors at Forever Institut, a small amateur tattoo in black ink on light skin can be removed in 4 to 6 sessions. On the other hand, a large polychrome tattoo done by a professional using dense coloured inks may require 12 to 15 sessions, sometimes more.

The interval between two sessions is 6 to 8 weeks. This period is not an arbitrary constraint: it corresponds to the time needed for the body to evacuate the fragments of ink produced during the previous session and for the skin to regenerate completely.

This variability is explained by the following factors, which are detailed below.

Criteria for determining the number of sessions

1. The colour of the ink

This is the most important factor. Black ink absorbs all wavelengths of light, so it responds most quickly and completely to lasers. Red, orange and yellow inks are more selective: they require specific wavelengths and respond less well to standard lasers.

Green and blue inks are the most resistant. Some pigment formulations used in professional studios contain compounds that absorb laser light poorly, multiplying the number of sessions required.

2. The size and complexity of the tattoo

The size of the tattoo is not related to the effectiveness of tattoo removal. The density of the line does, however, play a role: a very heavy tattoo, with saturated areas of fill, will require more sessions than a tattoo with a fine line. The quality of the ink will also play an important role in the effectiveness of tattoo removal: inferior quality ink will take longer to remove.

3. Age of the tattoo

Counter-intuitively, an old tattoo is not always harder to remove. Over time, the body has already begun to naturally fragment some of the ink. A recent tattoo, less than a year old, has ink that is not yet well stabilised in the dermis and so may respond better to laser treatment.

In both cases, the protocol can be adapted. A tattoo that is more than ten years old can sometimes be treated in fewer sessions than one that is five years old, simply because some of the pigmentation has already faded.

4. Quality and type of ink

Tattoos made by amateurs or with low-quality inks are often easier to remove. The ink is generally less dense, deposited less deeply in the dermis, and more homogeneous. A professional studio tattoo, on the other hand, uses concentrated, multiple inks deposited with precision - which gives a superior aesthetic result, but makes tattoo removal more complex.

5. Your skin type

On fair skins (phototypes I to III), the contrast between the ink and the skin is maximal. The laser can work at higher fluences, which improves effectiveness at each session. On dark or matt skins (phototypes IV to VI), it is important to adjust the wavelength and to treat the tattoo with Nd:YAG to avoid any risk of hyperpigmentation. 

6. Location on the body

Blood and lymph circulation in the treated area influences the speed at which ink fragments are eliminated. Tattoos located on the extremities (ankles, feet, hands) respond more slowly than those placed near the trunk, where lymphatic circulation is more active.
In practice, the Forever Institut teams note that a tattoo on the foot may require two to four extra sessions compared to the same tattoo on the arm or shoulder.

Number of sessions depending on the type of tattoo and ink colour

Which laser technology is best for tattoo removal?

Not all lasers are created equal. For tattoo removal, the current reference technology is the picosecond laser, and this is precisely the equipment used at Forever Institut.

Le picosecond laser emits pulses 100 times shorter and more powerful than previous generation lasers. This infinitesimal pulse duration, of the order of a picosecond, or a thousandth of a billionth of a second, breaks up the ink particles into much smaller microparticles than with a conventional Q-switched laser. The immune system then eliminates them more quickly, which translates into better results on stubborn colours and resistant inks that are resistant to previous technologies.

During the initial consultation, our specialists determine the wavelength best suited to the dominant colour of your tattoo and your phototype. This is a decisive stage: selecting the wrong wavelength can be ineffective on certain colours, or cause avoidable skin reactions.

Make an appointment for a tattoo removal consultation

Each tattoo is unique. The only way to get an accurate estimate of the number of sessions - and therefore the cost and total duration of the treatment - is to consult our doctors.

At Forever Institut, the initial consultation enables us to analyse your tattoo, assess the colours present, determine your phototype and draw up a personalised protocol. A laser test can be carried out on the same day.

Our clinics in Geneva, Lausanne and Nyon offer laser tattoo removal consultations. Book an appointment directly online at www.forever-beauty.com or by telephone.

Are you hesitating between’permanent laser hair removal and Intense Pulsed Light (IPL)? This is a question we hear regularly at Forever Institut. Although both technologies use light to treat unwanted hair, they have significant technical differences that directly influence their effectiveness, safety and results.

In this article, we explain exactly what distinguishes medical lasers from IPL, why Forever Institut has chosen the latest-generation laser, and how to choose the method best suited to your needs.

What is laser hair removal?

Laser hair removal is a medical technology that uses a monochromatic beam of light, i.e. a single wavelength, to precisely target the melanin in the hair follicle. This highly concentrated light is absorbed by the hair pigment, transformed into heat and then permanently destroys the root without damaging the surrounding tissue.

At Forever Institut, we use Clarity by Lutronic lasers, equipped with two complementary technologies:

• The Alexandrite laser (755 nm): ideal for light to intermediate phototypes (skins I to III). Very effective on fine and medium hair.
• The Nd:YAG laser (1064 nm): designed for darker phototypes (IV to VI) and sensitive areas. Penetrates more deeply and reduces the risk of burning on dark skin.

These medical lasers also incorporate an advanced skin cooling system that protects the epidermis during treatment and makes the session less painful.

What is IPL (intense pulsed light)?

IPL (Intense Pulsed Light) is not strictly speaking a laser. It is a technology that emits a broad spectrum of light, consisting of several wavelengths generally between 500 and 1200 nm.

Unlike lasers, whose light is focused and monochromatic, IPL disperses its light over a wide range. This diffusion makes the treatment less targeted: the light reaches not only the hair, but also adjacent structures such as the epidermis, blood vessels and surrounding pigments.

IPL is often offered in non-medical beauty salons or as a home appliance. Although it can temporarily reduce hair growth, the results are generally less long-lasting and less uniform than those of medical lasers.

The major technical differences between laser and IPL

1. Precision and targeting of the hair follicle

Medical laser The unique wavelength enables ultra-precise targeting of the hair's melanin. Each pulse acts exactly where it should, selectively destroying the follicle.

IPL the broad spectrum disperses the energy over several targets simultaneously (hairs, skin pigments, vessels). This dispersion reduces the effectiveness on the follicle and increases the risk of side effects such as burns or hyperpigmentation.

2. Penetration power and depth

Medical laser The concentrated light penetrates deep down to the hair root, even in areas with deep follicles (bikini line, underarms, back). Medical lasers such as Clarity achieve high fluence, guaranteeing effective destruction.

IPL Dispersed energy limits the depth of penetration. Deep follicles may not be heated enough to be destroyed, which is why results are often incomplete.

3. Safety and adaptation to skin type

Medical laser Thanks to the precise settings and selection of the appropriate wavelength (Alexandrite or Nd:YAG), the laser is perfectly adapted to each phototype. Built-in cooling systems continuously protect the epidermis.

IPL IPL: the broad spectrum increases the risk of skin reactions, especially on dark, tanned or sensitive skin. Darker phototypes (V and VI) are generally contraindicated for IPL, as the technology cannot effectively differentiate between hair melanin and skin melanin.

4. Sustainability of results

Medical laser According to Forever Institut's clinical protocol, developed over more than 25 years of practice in Geneva and Nyon, laser hair removal offers a permanent reduction of 80 to 90 % in hair growth after a complete protocol of 7 to 10 sessions. Treated hair does not grow back, or only occasionally, particularly in cases of hormonal upheaval.

IPL The results are temporary to semi-permanent. Regrowth is frequent after a few months, requiring regular maintenance sessions. IPL slows down hair growth but does not eliminate it permanently.

Comparison of light hair removal technologies - Forever Institut, Geneva.

Why has Forever Institut chosen medical lasers?

Forever Institut has been using the most advanced laser hair removal technologies for over 25 years. Our choice of the Clarity by Lutronic medical laser is based on rigorous scientific and clinical criteria:

• Proven effectiveness: thousands of patients successfully treated in our clinics in Geneva, Nyon and Lausanne.
• Maximum safety: integrated cooling systems, personalised settings and constant medical supervision.
• Adaptability: two wavelengths (Alexandrite and Nd:YAG) to treat all phototypes in complete safety.
• Patient comfort: quick, painless sessions with no social eviction.
• Lasting results: permanent reduction in hair growth after the full protocol.

We have deliberately avoided IPL because of its technical limitations and less predictable results. Our commitment to excellence and patient satisfaction drives us to use only the highest-performing medical equipment.

How do you choose between laser and IPL?

The choice between medical laser and IPL depends on your objectives, your skin type and your expectations in terms of results.

Choose a medical laser if :

• You're looking for permanent, long-lasting hair removal.
• You have matt, dark or sensitive skin.
• You want to treat deep or sensitive areas (full bikini line, back, chest).
• You give priority to safety and medical supervision.
• You want an effective treatment from the very first sessions.

IPL may be suitable if :

• You have very light hair growth and fair skin (phototypes I to III).
• You accept temporary results requiring regular maintenance.
• You're looking for a cost-effective short-term solution (beware: the total cost over several years may exceed that of the laser).

At Forever Institut, we systematically recommend medical lasers to guarantee optimal, safe and long-lasting results. During your initial consultation, Our specialists will assess your situation and guide you towards the most appropriate protocol.

Dr Polla, anchoring change
Forever is first and foremost the mark of one man: Dr Polla, a visionary pioneer who ushered in a new era in aesthetic medicine, one of precision, naturalness and innovation. His institute was never simply a place for treatment: it was a whole philosophy! An art of gesture that whispers rather than imposes. An approach where the human element always comes before the technical. This soul, this signature, survives the move intact. Forever keeps its heart, even if its walls change.

Leaving an address, taking a story with you
Twenty years in the same rooms... That leaves traces, laughter, confidences, whispered transformations under the light of a medical lamp. Leaving these walls is like releasing a last embrace: a bittersweet pinch, a breath between nostalgia and impetus.

But it also means accepting that beauty, like skin, is a process of renewal. That we grow by changing our skin.

Movement as rebirth

3 rue du Commerce is brighter, more fluid and designed to welcome the future with a new flow. A space redesigned to amplify Forever's strengths: precision, expertise and that special delicacy that floats between the scientific and the sensitive. The transition is never a smooth one: stacked boxes, architect's plans, delays, dust. But behind every chaos lies a sparkle. And behind this construction site, an obvious fact: Forever is moving forward, reinventing itself, breathing differently.

A new door, the same scope
The institute will be closed from 3pm on 22 December until the morning of 7 January. A time suspended, like a deep breath before blossoming again. And then January will slip by, with its fresh breath, opening a new door on a still virgin chapter. With the same team, the same human warmth, the same high standards. Because while the address may change, the soul remains perfectly unchanged.

Journalist : We've been hearing a lot about PRF and EZ Gel recently, especially since the’Hailey Bieber said he would do so at his last interview. Can you explain what this is all about?

Dr. Raphaël Wahlen - Aesthetic doctor : PRF and EZ Gel represent an innovation in regenerative medicine, an evolution of the well-known PRP. These treatments are made from the patient's own blood, without any additives, and concentrate growth factors and regenerative cells. Once injected, they stimulate the production of collagen and elastin, promote cell regeneration and improve the overall quality of the skin.

Journalist : How does the FRP differ from the traditional PRP?

Dr. Wahlen : PRP contains mainly platelets and their regenerative factors. PRF, on the other hand, is centrifuged more gently, so that white blood cells and stem cells are also preserved. Once injected, it forms a natural fibrin matrix that gradually releases the growth factors, prolonging collagen stimulation and cell regeneration over time.

Journalist : What is EZ Gel and how is it prepared?

Dr. Wahlen : EZ Gel is an autologous gel, i.e. obtained from the patient's own blood. Two tubes are taken: one is heated to transform the albumin into a gel, and the other is used to recover the PRF. By mixing them, we obtain a gel-like texture containing the regenerating factors of the PRF. This gel acts as a natural light volumiser and, above all, regenerates the skin. The regenerative action is longer-lasting than that of FRP alone, thanks to the enveloping and protective action of the gel. However, the volumising effect does not last as long as with an industrial hyaluronic acid filler.

Journalist : Why is this treatment so popular in the field of beauty and skin regeneration?

Dr. Wahlen : Because it's part of a major trend: natural regeneration. More and more patients are looking for visible but subtle results, without resorting to fillers. PRF and EZ Gel optimise the skin's natural potential, encouraging regeneration rather than correction. The treatment is safe, with no allergic risk or overcorrection effect, and can often be suitable even for those who cannot benefit from other techniques.

Journalist : What are the main benefits for the skin?

Dr. Wahlen : They improve the overall quality of the dermis: radiance, density, firmness and elasticity. PRF and EZ Gel reduce fine lines, restore volume, lighten dark circles and help tissue repair. They can also help to improve certain hyperpigmentation or light scars. As with other biostimulation treatments, you need to have reasonable expectations and patience to see how effective the treatment is over time.

Journalist : What areas can be treated?

Dr. Wahlen : PRF and EZ Gel are particularly good for the delicate area around the eyes. I like to combine the two treatments in several layers for optimum regenerative action. They can also be used all over the face, and even on the scalp and hands.

Journalist : Is it a preventive or corrective anti-ageing treatment?

Dr. Wahlen : Both. For young skin, it's an excellent preventive treatment that maintains skin quality and revives radiance. For more mature skin, it stimulates the repair and collagen production processes.

Journalist : How many sessions are needed to see results?

Dr. Wahlen : In general, two to three sessions spaced four to six weeks apart are recommended, followed by a maintenance session once or twice a year. The response varies from person to person, as it all depends on the skin's natural capacity for regeneration.

Journalist : Can it be combined with other treatments?

Dr. Wahlen : Yes, FRP works very well with skin boosters, biostimulants such as Radiesse, Sculptra or polynucleotides, as well as certain peels. It enhances their effects by improving the quality of the dermis.

Journalist : Are there any contraindications or side effects?

Dr. Wahlen : The procedure should be avoided in the case of coagulation disorders, certain autoimmune diseases, anticoagulants, active infection or pregnancy. Side effects are slight: slight swelling may occur for 1 to 3 days in general, but as with all injections there is a risk of haematoma.

Journalist : Is the treatment painful? Is there any social exclusion?

Dr. Wahlen : The injections, which are never pleasant, are not usually painful. Some people resume their activities immediately, while others may experience slight swelling for 24 to 72 hours.

Journalist : Do you think the FRP will replace the PRP?

Dr. Wahlen : Rather, it is an additional treatment available. PRP remains a recognised treatment. The choice always depends on the indication and the patient's profile.

Journalist : What role do you see for FRP and EZgel in the future?

Dr. Wahlen : A place of choice in modern regenerative aesthetic medicine, in association with other biostimulation treatments. They fit in perfectly with biostimulation protocols aimed at preserving the skin's health and beauty naturally, sustainably and safely.

Pink October is hemming the city in with ribbons like so many threads of courage. At Forever Institut, Dr Lydie Chevriaux, a multi-talented aesthetic doctor who specialises in intimate gynaecology, weaves a singular medicine: a medicine that doesn't just repair tissue, but sews up self-esteem, soothes invisible scars and rekindles the embers of desire. Between care and beauty, it gives voice to the body and breath to the soul. 

An intimate conversation with a doctor. 

Your career path resembles a moult: from general medicine to gynaecology, then on to intimate aesthetics. How did this path take shape, almost as a matter of course?
I started out as a general practitioner, and little by little a lot of patients came to me for gynaecological follow-up. Fitting IUDs, contraceptive implants, pregnancies... it all came naturally. As a woman and a doctor, I quickly felt that meeting these needs filled a gap. Then a laboratory contacted me and said: "You already practise gynaecology, so why not train in its aesthetic dimension? I agreed, without any taboos! 

When we talk about intimate health, we're talking about confidence and modesty, but also beauty and well-being. Was it natural for you to combine skincare, beauty and self-confidence?
Yes, because everything is intimately linked. Vaginal dryness, for example, strikes many women after cancer or heavy treatment. All too often, they still hear: "There's no solution, you just have to learn to live with it". But restoring comfort and self-confidence is already a cure. Two out of three patients come to see me after having been badly treated, either by illness or by medical silence. That's when aesthetic gynaecology comes into its own: a deeply human response that goes far beyond appearance.

Behind the closed doors of your practice, what are the most common reasons why your patients come to you?Vaginal dryness is the main cause, often linked to cancer treatments or the menopause. But there are also functional problems: pain when playing sport, discomfort when wearing tight clothes, or a loss of confidence in intimacy. Some come for labia majora reshaping, others to get their sex life back on track after years of hiatus. It's never "on a whim": it's a need for comfort and dignity.

Today, techniques are multiplying... How do you choose the right gesture, the right note, to re-tune the intimate?
There are several approaches. Hyaluronic acid injections, which rehydrate and restore. Radiofrequency, which improves vaginal suppleness and treats vaginismus. More recently, biophotomodulation uses light to stimulate collagen and balance intimate flora. Each protocol is chosen according to the patient's history. It's never standardised, always personalised.

You often talk about singular stories. Do you have an anecdote that illustrates the alchemy between medical care and personal rebirth?
A 68-year-old patient, widowed for almost two decades, had found the impetus of a new partner. Eighteen years without intimacy had left their mark, to the extent that a first intercourse caused her to tear her vagina. We worked on rehydrating the tissues, but also on relearning the language of attention: I took the time to talk with her partner, to evoke the tenderness of foreplay, the importance of delicacy. This dialogue proved to be as therapeutic as the medical procedure itself. Because, as I often say, in these cases, communication between the couple is an integral part of the healing process.

In this month of Pink October, your arrival at Forever Institut is symbolic. What message would you like to send to women who are still reluctant to cross the threshold of an office to talk about intimacy?
Dare to talk about it! There's nothing taboo about intimate health: it deserves the same vigilance as your heart, skin or eyes. Find a doctor with whom you feel confident, and confide your questions to him or her, even if your voice trembles when you put them down on paper. Cosmetic gynaecology is not a whim: it's a medicine for regaining comfort, sewing up self-esteem and reinventing relationships.
