Scars are a part of the natural healing process after trauma to the skin following surgery, acne, cuts, scrapes, sores or burns. The body forms new collagen fibers to mend the damage, which results in a scar. The formation of the scar depends on a couple of different factors including how deep the wound is, where the wound is located, the length in time it takes the wound to heal, the age of the individual and the inherited tendency to scar. There are several different types of scars including Keloid scars, contracture scars, hypertrophic scars and acne scars. Keloid scars and hypertrophic scars occur when the body produces too much collagen fibers. Scars cannot be completely removed, but certain medications and therapy can improve the appearance of them. Treatment options include topical medications, surgery, steroid injection, radiotherapy, dermabrasion, laser resurfacing and filler injections.
