Acne can leave scars behind to remind us of its destructive nature and the scars can be just as traumatic to the self-esteem as the acne itself. Scars can vary from one or two simple discolored marks to large areas covered in disfiguring indentations. The American Academy of Dermatology notes that a scar is part of the healing process and is the result of the skin repairing itself from diseases. Surprisingly, the younger the person, the stronger the healing process, resulting in thicker, larger scars.
Dermabrasion
Dermabrasion is the removal of the top layers of skin by an electric device with a rotating wire brush. New skin forms as the wound heals to smooth away scar visibility. According to the Mayo Clinic, surface scars may be removed completely with dermabrasion. Deeper scars may appear less noticeable or require a different treatment. Multiple treatments may be required.
Laser Resurfacing
Laser resurfacing is the removal of the top layers of skin while heating the sub layers of skin, forcing new skin to form as the wound heals from dermabrasion. The American Academy of Dermatology notes that following treatment, a certain amount of healing time will be required and skin may remain pink for several weeks or months while the skin heals. Multiple treatments may be required.
Chemical Peels
Chemical peels involve applying a chemical, usually a form of acid, upon the skin to peel away the top layers of skin. The depth of the scars, the type of scars and the color of the scars will help the dermatologist determine which chemical is appropriate for your situation.

Punch Techniques
Punch techniques are used specifically for deep, "ice-pick" shaped scars. Similar to how hair is removed for hair-transplants, the scar is punched out of the skin. Punch replacement places a skin graft over the leftover hole. Punch excision closes the hole and allows it to heal.
Punch elevation leaves the scar instead of removing it after loosening it to allow it to float to the skin's surface, providing a more even effect. It is not uncommon for punch techniques to be used in conjunction with laser resurfacing or dermabrasion.
Augmentation
Augmentation is used for deeper scars, and is when a substance is injected under the scar to raise it to the skin's surface. Various forms of collagen or the patient's own body fat can be used. Results are temporary, and depending upon the substance used, repeated treatments may be necessary every six months.
