A much more aggressive scar treatment is dermabrasion. This procedure should only be done by a dermatologist.
A local anesthetic will be injected to numb the area, and as ice packs applied to the area to harden the skin. A tool is then used with a rotating head made of a wire brush or diamond wheel to remove the top layers of skin.
By doing this, the surface of the skin is injured and new skin will regenerate to replace the damaged areas. This treatment is used most commonly for acne scars and keloid scars. After your treatment, the same rules apply as above for wound treatment.
As painful as this treatment sounds, many people recover quickly and go about their normal activities the same day. New skin will regenerate within eight days and return to your natural skin tone within 12 weeks. Sunscreen is an absolute must when healing from this process, as with any scar tissue, the skin is new and sensitive to UV rays.
