Surgical treatment of acne scarring: non-linear scar revision.

Non-linear scar revision techniques involve levelling facial skin. Classification as to the nature of the pitting allows the surgeon to select techniques to improve the facial cosmetic appearance. The types of intradermal pitting and subcutaneous atrophy along with nodular scarring produce the lack of levelling and the depression that the patients want corrected. The useful modalities available to level facial skin are dermal levelling, injectable substances, dermal punch grafting, excision and facelifting. The selection of these techniques is dependent on the above classification and the patient's desire for improvement.
