This intensive overnight moisturizer helps restore skin to its healthiest state by supporting skin’s four essential building blocks (proteins, micronutrients, water and lipids). Retinol helps improve cell turnover, visibly enhance firmness and elasticity and diminish the look of lines and wrinkles, while patented NIA-114™ technology helps limit the sensitivity common to Retinol. Copper Tripeptides, plant lipids and hyaluronic acid help rehydrate skin, lock in moisture and defend against environmental aggressors. Skin appears more refined and youthful-looking overnight.
