Uniquely formulated with anti-aging superstars Retinol and Vitamin C, this lightweight & luxe moisturizer firms, brightens and nourishes skin overnight while improving texture, tone, and the look of fine lines and wrinkles. Our Skin Health Experts' Approach To Using Retinol: Because Retinol is such an effective and active ingredient, only use one product containing it on any given day. To see visible results from the products in this set, apply on alternate evenings and no more than 4 times per week. Monitor any skin sensitivity and adjust product use accordingly.
