Collagen is responsible for keeping the skin tightened and smoothened. When the skin starts aging, the collagen amount decreases which gives rise to fine lines and wrinkles. Collagen accounts for about 80% of the human skin structure providing strength and firmness to the skin.
Especially type I and III collagen increase the skin elasticity more, thereby, minimizing the skin wrinkles and bringing a youthful glow. The best collagen stimulating treatments can effectively tighten the loose, saggy skin.
