Dermabrasion is a surgical process that resurfaces the skin
by the use of a drill-like tool that has an abrasive wheel.
This abrasive portion is run over the top of the scar
resulting in the removal of the top layers of the skin. This
procedure may take only a few minutes for small areas and
approximately two hours for larger surfaces.
Another way of clearing acne scars is by laser resurfacing.
This procedure utilizes carbon dioxide and erbium:YAG to
burn the surface skin layer, thus revealing the skin
underneath. Healing after the treatment takes about two to
four weeks and is generally without pain. However, this
procedure does not remove very deep scars.
Dermal fillers such as human and bovine collagen, fat, and
different forms of hyaluronic acid can also be injected into
pitted acne scars to smoothen the skin. However, the result
is not permanent and the procedure has to be repeated.
For deep scars, the surgical procedure Punch Excision can be
used. In this treatment, the bottom part of the scar is cut
out using a small round tool. The walls of the scar are
sutured and the scar produced disappears with time.
Punch Excision with Skin Graft Replacement is a surgical
procedure similar to the procedure described earlier, but
instead of stitching the walls of the scar together, a skin
graft is used. Ear skin is usually used, and this might
result in uneven appearance because of the difference in
texture and color. Thus, a resurfacing procedure may be
required after the surgery.
Subcutaneous incision or Subcision is another surgical
procedure that cuts the fibrous bands under a scar. This
procedure allows the skin to regain its normal appearance,
but may cause too much bleeding and formation of a mass of
tissue under the skin also known as subcutaneous nodules.
