Hydrolyzed Collagen is a clinically proven nutraceutical that is made with a gelatin-like protein and amino acids derived from fish oil which hydrate the skin and connective tissues. In addition, it helps elasticity for smoother, firmer-looking skin. The extraction process for fish collagen preserves its triple-helix structure, thus keeping polypeptides and amino acids intact. (Find this in Skin Uplift Serum, Beyond CP, Eye Perfect and Deep Penetrating LED Peptide Serum).
