Overview

Scarring occurs when the skin naturally repairs wounds, such as those caused by acne lesions. It is a natural part of the body's healing process, but if you are experiencing scarring caused by acne, you may want to consider one of the many treatments available to reduce or improve scarring. You can discuss the available options with your dermatologist to determine the right one for you.

Dermabrasion

This procedure is used to treat shallow or minor imperfections or scarring. In this treatment, a dermatologist uses a rotating instrument to remove, or "sand," the top layer of skin. The new layer beneath the surface is smoother and scars are less noticeable. You usually receive a local anesthetic and the procedure takes about half an hour to an hour. Recovery time is about one week.

Laser Resurfacing

A laser, or high-energy light, is used to remove damaged skin due to minor acne scarring so new skin can grow in its place. There are several types of lasers available, depending on what treatment is needed. Redness and swelling will probably occur for about one week after the procedure, but your skin may stay pink for several more weeks or even months. Normal activity can usually resume in about one week.

Punch Grafts and Punch Excisions

If your acne scars are deeper, you may want to consider one of the punch techniques. A punch graft is a technique used to replace damaged skin with normal skin. The scar is cut out and the hole is filled with normal skin, usually taken from behind the ear. Punch grafts take five to seven days to heal.

Punch excisions are closed with stitches, which are removed in five to seven days. Both punch techniques are used for deep, or pitted acne scars, and once your skin has healed, your skin will appear smoother.

Chemical Peels

Chemical peels work well for mild or superficial acne scars. A chemical solution is applied to the affected area, causing the skin to peel off. New skin will grow, which is smoother and has better texture. The depth of the peel and acid solutions can vary, so recovery can take from one day to several weeks. Redness, swelling and dryness are common side effects after treatment. Unlike punch techniques, chemical peels are not recommended for deeper acne scars.

Soft Tissue Fillers

This procedure involves the injection of soft tissue fillers into your skin, which elevates, or fills, soft acne scars. Fillers can include bovine or human collagen, or hyaluronic acid. You will see immediate improvements, including a smoother complexion and scar reduction. The results are not permanent, however, so the procedure will probably need to be repeated in order to maintain the desired results.
