Subcision is a minor surgical procedure used for treating depressed / indented scars. It is performed under local anaesthetic using a special needle 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 or the fibrotic strands and new collagen deposition caused by wound healing leads the cosmetic improvement of the scar.
Interval of at least one month in between treatments are generally recommended.
Individuals vary in their ability to form collagen and healing. The number of subcisions required will depend on the type, location and severity of depression and intensity of treatment. Usually, 3-6 visits suffice for the majority of moderate scarring.
Pain, bleeding, bruising and infection can happen as early side effects of the treatments. Some change of skin pigmentation can temporarily occur after healing. Therefore, sun protection or avoidance is advised.
