Dermabrasion is a method of exfoliating the skin, using a rotating wire brush or diamond wheel, which removes the top layers of skin over and around the scar. In the weeks following the procedure, new skin will grow back, and the appearance of the scar will be greatly reduced. Dermabrasion is usually used for acne and other facial scars, though it can be performed on the legs by a qualified surgeon. Dermabrasion on the legs is a delicate procedure as the skin on the legs is very thin and runs the risk of doing more harm than good if done incorrectly.  Dermabrasion on the legs is usually only recommend for dark spots or indented scars caused by mosquito bites, etc. Keloid or hypertrophic scars (raised scars) should not be treated with dermabrasion. Make an appointment with a board-certified plastic surgeon who can analyse your scarring and decide whether you are a good candidate for dermabrasion. Be aware that these kinds of aesthetic procedures are not usually covered by insurance. Chemical peels can be used to treat superficially scarring on the legs, and works particularly well for scars caused by hyperpigmentation. During a chemical peel, a dermatologist will apply a layer of acidic solution to the scarred skin and leave it on for approximately two minutes. You will experience a burning sensation, which should cease once the acid has been neutralized and the solution washed off. In the two weeks following the procedure, the top layers of skin will begin to peel away, leaving smooth, new skin behind.  Depending on the scarring, you may need to go through several chemical peel procedures before you see a noticeable difference in the appearance of your skin. Be aware the new skin that is exposed after a chemical peel will be particularly sensitive and you will need to protect it by avoiding sun exposure and using a sunscreen with a high SPF for several weeks. Laser treatment is a great option for improving the appearance of deeper scars than those targeted by dermabrasion and chemical peels. Laser treatment...
