Acne Scar Subcision
What is subcision?
Subcision is a procedure used to treat acne scarring. It involves the breaking down of scar tissue beneath the skin manually to smoothen acne scars.
How does it work?
Acne scars are caused by inflammation, which sometimes results in the formation of scar tissue under the skin. Scar tissue is formed by collagen fibres arranged in a haphazard way due to abnormal healing of the skin from acne. This arrangement of scar tissue pulls or tether the skin inwards, causing the skin to form depressed, pitted scars.
A subcision is performed using a specialised, sharp needle to break down the scar tissue under the skin that cause acne scarring. A scratching sound can sometimes be heard during the subcision procedure, which is due to the breaking up of built-up scar tissue.
After these scar tissues have been broken down, the skin starts healing properly without the presence of inflammation. The release of the fibrotic strands of scar tissue and new collagen deposition caused by wound healing leads to visible improvement of the scar.
Note: Not all type of scarring responds well to subcision. Subcision is best used on depressed rolling and box scars. Ice pick scars will not yield good results from a subcision procedure.
Do note that a sharp needle should always be used for a subcision procedure, as a cannula (blunt needle) cannot break through the scar tissue and is not effective. Due to the nature of the procedure, some bruising can occur.
Subcision results are best when combined with the Rejuran S or fractional lasers/procedures.
Is it painful?
The procedure requires numbing cream as it requires a small sharp needle for the subcision procedure. There is slight discomfort during the procedure but is mostly tolerable.
Is there downtime?
Subcision can have a downtime of about 2-3 days, with some redness and bruising. Usually when combined with a fractional laser/procedure, downtime can be about 4-5 days. You are advised to avoid strong sun exposure for at least 7 days after the procedure.
How effective is the treatment?
Like all scar removal procedures, results can vary depending on the condition. A subcision procedure greatly increases the results of scar removal when combined with fractional lasers/procedures by approximately 30-40%.
