Punch Technique for Acne Scar Removal

Punch techniques are typically used for deep acne scarring like "ice pick" scars. The procedure involves the physical removal of the tissue containing the scar and either the suture or replacement of the remaining tissue. There are three main punch techniques used.

These are:

Punch Excision

A punch excision utilizes a punch biopsy tool which may vary in width depending on the size of the treatment area, generally between 1.5 mm and 3.5 mm. Local anesthesia is applied to the area and the tool is used to remove the scar and its surrounding edges. The scar now removed, the skin is sutured together and heals. The scar produced from treatment typically fades after treatment.

Punch Excision with Skin Grafting

Punch excision may also be performed with the inclusion of a skin graft in the place of a suture. The scar will be removed with a punch biopsy tool and rather than suture the wound, the physician will fill it with a skin graft of the patient's own skin.

Punch Elevation

Punch elevation is used mainly on deeper boxcar scars. The concept is to remove the scar using the same excision technique where a biopsy tool removes the scar, but rather than suture or graft the wound, the scar tissue is then elevated and reattached. This diminishes the depth of the scar and minimizes the likelihood of discoloration from different skin being grafted in its place..
