Subcision is a minor surgical procedure using a hypodermic syringe or metal cannula to release tethered scar tracts under the skin surface. This procedure is usually combined with other treatments too enhance production of more collagen to lift up indented scars such as radiofrequency microneedling, fraxel laser, and filler injections.
Treatment consists of 1-4 sessions one month apart. Each session should take 30 to 40 minutes. The instruments will be manipulated in a horizontal direction just below the skin surface to release tethers. It may be mildly to moderately uncomfortable depending on the sites treated.
Caution is required in those with allergies to numbing injections, easy bruising (including use of anticoagulants), and those with prior facial injuries from burns or trauma.
