Scar revision minimizes the color, shape, size and texture of a scar. The treatment varies according to the scar size and the location on the body. Topical creams, ointments and gels can be purchased over-the-counter to alleviate redness, itchiness and scar sensitivity. Collagen injections help raise, or fill-in, a sunken scar. Cortisone injections soften and shrink scars which have become hard. Microneedling penetrates the dermis with bipolar RF energy to heat the skin and promote collagen. Surgical scar removal excises wide, deep and long scars and scars that had trouble healing. Chemical peels and lasers eliminate scars that are red and itchy.
