Hi, this is Dr. Yuki! Do you know “suvcision”?
Subcision is a minimally invasive surgical technique used to treat depressed acne scars, particularly rolling scars. It involves using a small needle or blade to break the fibrous bands of tissue that tether the scar to deeper layers of the skin. These bands are what cause the skin to pull down, creating the appearance of a depression or indentation.

How Subcision Works:
- Needle Insertion: A fine needle or cannula is inserted beneath the scar through a small puncture in the skin.
- Breaking Fibrous Bands: The needle is then moved back and forth to cut through the fibrous bands that are holding the scar down.
- Formation of New Collagen: As the fibrous bands are released, the skin’s surface lifts, and new collagen is stimulated in the treated area, which helps to further smooth out the skin over time.
Why Subcision is Effective for Acne Scars:
- Directly Targets Scar Tissue: Subcision addresses the root cause of depressed scars by releasing the fibrous tissue, leading to an immediate improvement in the appearance of the scar.
- Collagen Stimulation: The trauma caused by the needle during subcision also encourages the body to produce new collagen, which helps to fill in the depressed areas and improve skin texture over time.
- Minimal Downtime: Compared to other treatments like lasers or chemical peels, subcision typically has a shorter recovery period, with most patients experiencing only minor bruising and swelling.
In summary, subcision is a highly effective treatment for improving the appearance of depressed acne scars, offering significant results with minimal downtime. It’s a great option for those looking to smooth out their skin and reduce the visibility of scars.
