Collagen is the main protein of connective tissue, making up about one quarter of the whole-body protein in humans and other mammals. Collagen fibers in the tissue matrix of the dermis (the layer underneath the outer epidermis) support tissue and give strength and elasticity to the skin’s surface. Collagen acts together with hyaluronic acid and elastin in this matrix layer to maintain a smooth surface. Collagen also strengthens ligaments, bones, tendons and teeth and is found throughout the body in many forms.Collagen can be thought of as the ‘glue’ that holds your body together.

With age or illness the production of collagen slows down which results in a partial collapse of the tissue matrix in the derma, and a loss of tissue volume and firmness. Together with the slowing of hyaluronic acid production and reduced elastin, skin folds and wrinkles appear on the skin’s surface.

Though most collagen formulations have given way to more advanced injectable materials, there are still some types of collagen on the market.  With so many options for replacing facial volume, it’s always best to seek the help of a board-certified plastic surgeon or dermatologist to help you sift through the options.
