LRP La Roche-Posay B3 Retinol Anti-Aging Serum To Regenerate & Resurface helps skin instantly look smoother and more luminous. Progressively, the skin recovers firmness, and photoaging signs are corrected: deep wrinkles, fine lines, and uneven skin complexion. The formula is a unique complex of pure and gradual Retinol for continuous and potent anti-wrinkle action. Combined with Vitamin B3 for optimal regenerating efficacy, it promotes a more radiant and refined complexion. Pure retinol, a derivative of vitamin A, helps promote surface cell turnover and improves the appearance of fine lines and wrinkles. Niacinamide helps restore the skin's moisture barrier and visibly fades skin discolorations. This concentrated serum leaves the skin feeling smoother, hydrated and renewed for a dewy and healthy-looking glow. Pure and gradual release retinol helps to reduce the appearance of fine lines and wrinkles by stimulating collagen production, leaving the complexion brighter and more even.
