Collagen may be the most important element of human skin.

This complex protein makes up nearly 80% of skin and provides structure, elasticity and protection, while helping to retain moisture within the deep dermal layers.

As aging occurs, collagen naturally deceases over time.

Sooner or later, the reduction of collagen causes skin to become thinner, drier and more fragile.

Loss of collagen is believed to be the primary cause of fine lines and wrinkles that occur in naturally-aged skin.
