Retinol +AHA. Visibly reduces wrinkles. RoC experts in retinol bring you a new breakthrough in anti-wrinkle technology. Innovation: RoC has effectively combined the anti-wrinkle ingredient Retinol, with alpha-hydroxy acid (AHA), an ingredient known to exfoliate the skin. Its efficacy and tolerance have been clinically tested. 1st Action: An alpha-hydroxy acid (AHA) helps to refine skin's surface by exfoliating dead cells. Freed of these dead cells, skin surface is prepared for Retinol. 2nd Action: Retinol, a pure and active form of Vitamin A, then acts deep within the skin's surface. Wrinkles are smoothed from within. The Result: Retinol Actif Pur visibly reduces wrinkles in 8 weeks. Even more visible results in 12 weeks. Should be used at night, when the skin is at its most receptive for repair and cell renewal. Hypoallergenic, non-comedogenic.
