What Collagen Does

Collagen is a protein molecule made up of amino acids. It provides structural support between cells that make up the inner layers of connective tissues in our skin1. The connective tissue in the inner (middle) layer of the skin is composed of collagen and elastin fibers, which maintain the tension and elasticity of skin.2,3

Vitamin C and Skin Health

The antioxidant properties of vitamin C and its role in collagen synthesis make it a vital molecule for skin health. Vitamin C’s antioxidant activity is particularly important in the top (epidermal) layer of our skin,4 where its concentration is 425% higher than in the dermis.2 Ultraviolet light, especially UVA, is a common factor that induces skin oxidative stress.2,5 The antioxidant activity of vitamin C helps protect against UV-induced damage caused by free radicals.6

Cell culture studies have shown that addition of vitamin C might influence the ability of the skin to protect itself from water loss.4,7,8
