Scar revision encompasses various methods, alone or in combination. The chosen technique depends on the severity, location, and depth of the scar, also taking into account the health of the surrounding tissue. Different methods of skin resurfacing can treat acne scars. Dermabrasion resurfaces the top layers of skin and softens the appearance of scars. Laser resurfacing can stimulate collagen and elastic fibers, promoting healing and new skin growth.
Punch excision is a more focused procedure to address individual acne scars, repairing the wound with stitches or a skin graft. Another technique called subcision involves your doctor inserting needles under the skin to loosen fibers below a scar, to help improve its appearance.
Injection therapies are a minimally invasive option that offers precision and control. Dermal Fillers like Juvederm, Radiesse, and Restylane are popular treatments for acne scars. Fillers can reduce the uneven appearance of certain types of scars by filling depressed or concave scars. Results may last from three months to several years. Therapy must be repeated to maintain results. Steroid injections can be used to reduce collagen formation and can alter the size and texture of raised scar tissue.
