Glossary

Acne is a skin disease caused by the abnormally high activity of sebaceous glands that lead to an excessive secretion of sebum combined with a dysfunction in the maturation of keratinocytes and the abnormal development of bacteria called Propionibacterium acnes. Acne therefore occurs mainly in areas rich in sebaceous glands such as the back, neckline and of course the face. Acne can leave unsightly scars. Creams, peels, masks, lasers and various drugs can fight against acne.
