Subcision for Acne Scars
Subcutaneous incision, also known as Subcision, is used to break up the fibrous bands that cause depressed rolling acne scars in the skin.
Subcision is performed under local anesthesia by inserting a small needle under the skin so that it is parallel to the skin surface. Staying in the plane between the dermis and the subcutaneous tissue, the needle is gently advanced and retracted in a piston-like motion cutting the tethering bands. This will free up the depressed scars.
