According to the SFD (French Association for Dermatology), 15 million people in France suffer from acne, including 3.3 million over the age of 15. This skin disorder mainly affects teenagers, but also some adults. The number-one reason for consulting a dermatologist, this skin condition can lead to a lack of self-confidence and real psychological suffering.
By definition, acne is an inflammatory disease of the pilosebaceous follicle, resulting in oily skin and the appearance of pimples on the face. It's due to excessive sebum secretion by the sebaceous glands (dysseborrhea) and a dysfunction in keratin synthesis, which clog the skin's pores, favoring the appearance of comedones (blackheads and whiteheads). What's more, in this grease-rich environment, a bacterium usually present in small quantities on the skin, Propionibacterium acnes, proliferates, generating an inflammatory response on the epidermal surface.
This condition is often caused by stress, pollution, and hormones. However, a poor lifestyle (lack of sleep, smoking, unbalanced diet, poor hygiene…) can also trigger or aggravate acne.
