If you have serious scarring from previous bouts with acne, there are some things you can do. One form of treatment is laser resurfacing, which can be done in the doctor's or dermatologist's office. The laser removes the damaged top layer of skin and tightens the middle layer, leaving skin smoother. This can take anywhere from a few minutes to an hour. The doctor will try to lessen any pain by first numbing the skin with local anesthesia. It usually takes between 3 and 10 days for the skin to heal completely. Another method for treating acne scarring is dermabrasion, which uses a rotating wire brush or spinning diamond instrument to wear down the surface of the skin. As the skin heals, a new, smoother layer replaces the abraded skin. It may take a bit longer for skin to heal using dermabrasion - usually between 10 days and 3 weeks. Both of these types of treatments will cause skin to turn red, and this redness may last for several months. You can only have these treatments if you don't have an active case of acne at the time of treatment. Depending on the severity of your scars, your doctor or dermatologist may also suggest a more mild chemical peel or microdermabrasion, which are also done right in the office, to help improve the appearance of the scarred areas.

If you have minimal to moderate facial scarring from acne, a paste of asprin, vinegar, & water can be applied to the skin, & almost immediately you will see results, and continuation of the treatment over a month should give you very clear results. Asprin is basically salicylic acid that is commonly used to treat acne, & the vinegar is a PH balancer and sluffs off dead skin cells. Ingredients: 1/8 cup vinegar, 1/16 cup water, 10 asprins, Vitamin E, moisturizing face lotion. To use: Dissolve asprins in the mixture, leave set until it becomes a paste. Smear on affected areas and let the paste dry. After 10 minutes, wash the paste off with warm water, and then splash the face with cool water to close pores. Gently dab Vitamin E on the scars, and let it soak into the skin. Apply a facial moisturizer to keep your skin hydrated.
