Subcision

Understanding Subscision

Subcutaneous incisionless surgery (subcision) is an effective treatment for rolling scars. In this procedure, a hypodermic needle is introduced into the subdermal plane to undermine the scar through a series of backward and forward motions, followed by horizontally rotating the needle in a fanning motion.

These motions loosen the fibrotic adhesions that cause rolling scars and create a wound environment that promotes collagen deposition. The bleeding and subsequent clot formation that result from the procedure elevates the skin from the underlying scar tissue, creating a potential space for neocollagenesis.

Although subcision is adequate as a stand-alone treatment, better results are achieved when combined with other modalities. By loosening deep fibrous attachments, subcision may make acne scars more receptive to other treatment modalities as part of a multi-step approach.
