A scar forms when skin grows over a wound. It may fade with time, but never completely goes away and may stand out from the skin surrounding it as a pink or white patch, explains Medline Plus. Although most scars are harmless, they can cause difficulty opening the eyes and mouth when they are close to these areas. There are several methods to remove or improve scars; a dermatologist can help choose the best method for you.
Chemical Peels
The American Academy of Dermatology explains that chemical peels can treat small depressions and some larger scars caused by acne. They are not useful, however, at treating thick keloid scars or large scars with deep borders similar to chicken pox scars. Chemical peels use a solution, such as alpha hydroxy acid or phenol peel, that causes the top layer of damaged skin to blister and peel off, exposing the healthy tissue beneath. The most common side effects are stinging pain, redness that can last several months and increased sensitivity to the sun. It can take several procedures to reach your desired results.
Dermabrasion
During dermabrasion, a dermatologic surgeon freezes and mechanically sands your skin to remove the damaged areas and expose healthy tissue beneath, according to the American Society for Dermatologic Surgery. Dermabrasion is traditionally used to treat face scars from acne, chicken pox and accidents. After the procedure, your skin may feel friction-burned and your dermatologist may prescribe medication to alleviate discomfort. ASDS advises patients to avoid sunlight as much as possible for three to six months after this procedure and wear sunscreen outdoors.
Soft Tissue Fillers
Dermatologists use soft tissue fillers to improve scars caused by acne and injury. Types of fillers include fat taken from your own body, collagen and donor tissue. The filler works by smoothing and plumping damaged skin, explains the American Academy of Dermatology. Your dermatologist injects the filler under your skin using a fine needle. A series of treatments may be required to raise a depressed scar. Side effects include a stinging sensation during the procedure and temporary redness or swelling after.
Scar Revision Surgery
Severe scars such as those caused by burns may require cosmetic surgery. Scar revision surgery does not completely remove the scar, but it can make them significantly less noticeable. One method described by Medline Plus, Z-plasty, involves creating V-shape skin flaps around the scar through a series of small incisions. When the scar heals, it follows the natural folds of the skin and is less noticeable. Other surgical methods include skin grafting and tissue expansion with a silicon balloon.
