Sun damage to the skin can cause fine lines, uneven pigment and skin laxity, so we've formulated Lactic C Firming Cream as a hydrating and nourishing day/night cream designed to tone, smooth and balance aging skin. This combination of just enough alpha hydroxy acid and Vitamin C improve skin brightness. Lactic acid, an easily absorbed alpha hydroxy acid, increases skin's moisture capacity, thereby plumping up the surface and enhancing elasticity. This formula's bio-available Vitamin C also helps reverse the major signs of photo-damage.
