What is subcision?
Subcision, short for “subcutaneous incisionless surgery,” is a safe and simple surgical procedure for treating depressed acne scars. These depressed scars are created by fibrotic strands that pull the skin down, creating unsightly indentations. A hypodermic needle is inserted through the skin, which is then moved back and forth in a fan-like motion parallel to the skin. This breaks up the fibrotic strands which hold the scar to the underlying subcutaneous tissue. As new collagen forms, the depressions elevate and the overall smoothness of the skin improves.
