Collagen rejuvenates the skin from the roots and reduces wrinkles and symptoms of ageing. It's deficiency makes the skin dull and lifeless.
Vitamin C is a required component for the production of hydroxyproline and hydroxylysine, both of which are needed to bind the molecules that produce collagen. It protects the DNA from photochemical reactions that can lead to skin discoloration. It also inhibits the production of Pyrimidine Dimers that are the primary cause of melanomas in humans.
Vitamin C increases the formation of elastin which thickens, protects and heals the skin cells. The thickening effect helps retain moisture, increases the skin circulation and plumps up the skin surface.
