Correct deep wrinkles, premature sun damage and uneven skin tone with the La RochePosay Redermic Retinol. Made with 0.3 pure retinol, a vitamin A derivative which is the gold standard in treating wrinkles, the corrector stimulates collagen and elastin to firm and smooth the skin.ampnbsp Over time, skin becomes more even and firm, with fine lines and deep wrinkles appearing diminished. Premature dark spots are faded and the surface of the skin is visibly smoothed, with increased radiance. Apply in the evening to the face and neck. Use alone if skin is combination to oily, or beneath a moisturising cream if skin is dry. Do not expose skin to UV light. Apply a daily sunscreen with an SPF of at least 15.
