Subcision is usually performed for rolling acne scarring. It is performed using a special needle which is inserted through a puncture in the skin surface. The sharp edge of the needle is used to break fibrotic strands that are tethering the scar to the underlying tissue.
The release of the fibrotic strands and new collagen deposition caused by wound healing leads to cosmetic improvement of the scar.
Subcision may not be suitable in the following circumstances:
- Patients with a history of hypertrophic or keloid scars
- Current or recent (within 12 months) systemic oral retinoid (eg acitretin, isotretinoin)
- Bleeding or blood clotting disorders
- Active bacterial or viral infection
After the procedure
Pressure will be applied to the treatment site to reduce the risk of bleeding. You may be advised to continue with this at home.
How many treatments are required?
