One of these methods is subcision, which we'll look at in detail below.Subcision is a non-surgical, non-incision technique that can be used to improve the appearance of the skin of the face and remove acne and scars. This is a partial, outpatient surgery performed in the office. Subcegenation is the process in which a subcutaneous needle is inserted into the skin to manually break fibrotic strands that attach scar tissue to the subcutaneous layer. Hypodermic needles of various sizes are used to mechanically break the scar tissue inhabiting the surface, middle or deep layers.
