A scar is any mark left on the skin after an injury or wound has healed. Most will fade, but never disappear completely. There are several different types of scars, including fine-line, pitted/sunken, keloid and hypertrophic. Scars can be made less visible with camouflage make-up. Certain treatments, such as topical silicone gel, may also improve a scar’s appearance, and help make it less painful, itchy and/or restrictive.
