Collagen Lift Night SerumWhat it does: Visibly firms and plumps sagging skin with a concentrated collagen infusion. As collagen breaks down with age, skin loses its lift this serum actively works to restore it. Deeply hydrating and fast absorbing, it rebuilds skin's natural scaffold to give you firmer contours, fuller looking skin and a visible reduction in fine lines. The anti aging step you actually want to do every night.
