Chemical peels
Contrary to popular opinion, chemical peels are not dangerous. They are used to remove damaged skin layers and give room for a fresher surface. It would help to meet a dermatologist to help apply the peels. The concentration of chemicals in the peels depends on the level of scarring. The most common chemicals used include salicylic acid [4] and glycolic acid [5].
Dermabrasion
Dermabrasion works like chemical peels. It involves using a wire brush or laser. It reaches the deep areas of the skin, so it is often used for deeper scars.
