Glossary

Greasy skin is linked to the abundance and nature of the sebum excreted on the surface of the skin by the sebaceous glands. It is most often present in teenagers and young adults. Excess sebum gives it a shiny look, notably on the forehead, sides of the nose and chin. A greasy skin is thick, covered in an exaggerated lipidic film. It is nevertheless less sensitive to outside factors, to dryness and, thus less liable to wrinkles and marks of ageing.
