Collagen injection: Collagen, a normal substance of the body, is injected under the skin to “stretch” and “fill out” certain types of superficial and deep soft scars. Collagen treatment usually does not work as well for ice-pick scars and keloids. Collagen derived from cows or other non-human sources cannot be used in people with autoimmune diseases. Human collagen or fascia is helpful for those allergic to cow-derived collagen. Cosmetic benefit from collagen injection usually lasts 3 to 6 months. Additional collagen injections to maintain the cosmetic benefit are done at additional cost.
