Subcision is a simple and safe office surgery procedure for treatment of depressed acne scars. Subcision can easily be combined with other treatments such as laser, dermaroller and scar revisions for maximum efficacy. If the acne scarring has severe depressions, we usually do Subcision before we start with any acne scar skin rejuvenation treatments such as Fraxel Dual and Dermapen skin needling.
Subcision addresses depressed acne scarring. Unlike dermabrasion which treats scars by abrading them away, Subcision reduces the appearance of scarring from the underneath the skin’s surface. During the procedure, individual scars will be treated using a tiny, hypodermic needle that will be inserted into the skin. The needle will be moved back and forth in a fanning pattern as the sharp edges of the needle will be used to cut away at the fibrotic scar tissue. These cuts effectively release the tethers of the scar from the underlying tissue. This release elevates the previously depressed skin and will continue to improve as the wound healing cascade will stimulate further collagen production. Providers will be cautious around sensitive areas such as the eyes and mouth to avoid injury of facial nerves and vessels. If many scars need to be treated, treatment will be divided into multiple session.
What are the indications for Subcision?
The decision to perform Subcision will depend on the type, location, and severity of scarring; patient preference and expectations; and clinician experience and expectations. Subcision may be used for the treatment of:
- Depressed distensile scars (due to acne, trauma, surgery)
- Depressed bound down scars (due to acne*, varicella (chickenpox), trauma, surgery)
- Depressed skin grafts
- Cellulite dimples
After the procedure:
Immediately after subcision:
- Pressure and ice are applied to the operated site to maintain haemostasis and reduce the risk of bleeding.
- Make-up may be applied to camouflage bruised areas.
- Some authors recommend antibiotics and anti-inflammatory medication.
