Collagen is a protein that keeps skin tissue firm and supple, and is found throughout the body; in the cartilage, bones, muscles and tendons as well as in the skin. Our skin is composed of two different layers; the top layer is known as the epidermis, and the bottom layer is known as the dermis. Collagen is the main component of the epidermis and keeps the skin smooth and youthful looking.
Collagen is used by the body to repair itself, and promotes healthy hair and nails. It is essential for rebuilding and strengthening cartilage and promoting wound healing.
