The best chemical peel for acne scar removal, or at least to refine them a little, is a phenol treatment. A one-time procedure can also reduce deep wrinkles and remove precancerous growths. However, it is also the most expensive of peels available for skin treatment. The cost can range from under 3 thousand dollars to over 6 thousand dollars. Because it is more for cosmetic purposes, insurance will not cover the price, unless it is a medical treatment for precancerous growths. Unfortunately, even phenol cannot totally remove deep acne scars, but the treatment can at least make them less pronounced.
