Collagen Injections can be used to fill in creases, wrinkles, and depressions in facial skin, including laugh lines, smile lines, facial wrinkles, lip creases, crow's feet, and acne scars. It can also be used to treat areas of the neck, back, and chest, or to create plumper cheeks or lips. The injected collagen is derived from purified bovine collagen (very similar to human collagen) and has been FDA approved since 1981. |
