Radiofrequency-assisted subcision for postacne scars
Subcision is a commonly performed procedure for depressed rolling scars of acne.1 Breaking up the fibrotic strands mechanically with a blade or needle leads to neocollagenosis and hematoma formation, resulting in elevation of the depressed scars. However, the excessive mechanical force often leads to trauma to the surrounding tissue, excessive bleeding, and large hematoma formation and fibrosis.
