La Roche-Posay Retinol B3 Serum 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. Retinol B3 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 La Roche-Posay Retinol B3 Serum promotes a more radiant and refined complexion. Pure retinol, a derivative of vitamin A (retinoic acid) that is widely recommended by dermatologists, which helps promote surface cell turnover and improves the appearance of fine lines and wrinkles. Niacinamide, a widely used ingredient in dermatology for its soothing properties, helping restore skin's moisture barrier, and visibly fading skin discolorations. This concentrated serum is infused with vitamin B3 to leave 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. By combining these two powerhouse ingredients, the serum leaves the complexion looking brighter and more even.
