La Roche-Posay research has shown that under the effects of external aggressors like pollutant particles and dust, oily, imperfection-prone skin undergoes oxidation. This can trigger a chain reaction including hyper-keratinisation, sebum over-production, and oxidation of sebum and impurities on the skin's surface, which can lead to new imperfections. EFFACLAR K (+) daily care combines LHA with the antioxidant complex of VITAMIN E, CARNOSINE, and AIRLICIUM™. It refines skin texture, reduces the appearance of blackheads, and mattifies skin for up to 8 hours from the first application. Pores appear unclogged, skin texture looks smoother, and shine is controlled. Experience an all-day clean and fresh skin sensation. The ultra-fresh, aquagel texture is refreshing on application, ultra-light for quick absorption, and provides all-day comfort and moisturisation. Suitable for sensitive skin, hypoallergenic, and non-comedogenic. Tested under dermatological control.
