Collagen and Wrinkles

Collagen is a long, fibrous structural protein that is wound together in a tight helix. This helix is what gives collagen, and your skin, such great strength and elasticity. Numerous helixes bind together to form collagen fibers, which are woven together in our bodies like threads in fabric to form a framework for new cells to grow. Without these fibers, the skin just cannot hold its shape, making it look saggy and wrinkled.
By the age of 45, your body will have lost 30% of its collagen.

Degradation and depletion of collagen in the skin is the main reason for the formation of fine lines, wrinkles and the appearance of aging.
