When your skin is injured your body creates a tough fibre called collagen to repair the wound. Some scars sit flat on the skin, while some protrude. Scars that appear on exposed skin might be unsightly or even embarrassing. This is the natural way to prevent scars.
If you already have a scar you can use shea butter to break down the old scar tissue. First exfoliate the area in order to remove any dead skin cells. Next, massage the scar thoroughly to break down old hardened scar tissue. This will get your blood flowing in the area. For best results, apply shea butter to your scars at least 3 times a day.
