Treatment for oily skin with imperfections caused by external aggressions (pollution, tobacco, dust, etc.), which undergoes an oxidation process that causes various reactions in the skin (hyperkeratinization, overproduction and oxidation of sebum and impurities) which give rise to imperfections such as blackheads, open warts and non-even relief. To address this problem, La Roche-Posay's research department created Effaclar K+, a dermatological treatment for oily or acne-prone skin that renews the skin, is an antioxidant and offers an 8H anti-sebum treatment. Specially formulated for adult skin with enlarged pores, blackheads and uneven texture, Efaclar K+ detoxifies and purifies skin, smoothing texture and reducing pores, blackheads and shine.
