Uses: skin fillers
Injections of collagen can improve the contours of the skin and fill out depressions. Collagen can be used cosmetically to remove various lines and wrinkles from the face, as well as scarring (including acne), so long as the scars do not have a sharp edge.
Collagen fillers can originate from human and bovine sources. Use of injected collagen can be restricted in people with severe allergies, and skin tests are typically required before bovine collagen is used.
Collagen is used to fill relatively superficial defects. More extensive defects are usually filled with substances such as fat, silicone or implants.
