Crème Dermopurifiante, with its mattifying and astringent properties, is a skincare product designed to help reduce the appearance of excess oil and leave skin looking refined. It purifies the epidermis, helping to minimize the look of imperfections such as enlarged pores, blackheads, and blemishes. Its soothing ingredients work to improve the appearance of redness, giving the complexion a more even and calm look. Hyperseborrhea is the excess production of sebum, making the skin look oily and shiny. It is also one of the main causes of acne. This phenomenon may be linked to a multitude of endogenous (heredity, hormonal changes, stress, etc.) and exogenous factors (climate, pollution, diet, etc.).
