Abstract

Boxcar scars, such as chicken pox scars, are round to oval depressions with sharply defined vertical edges. Subcision is a simple and safe procedure for treatment of atrophic and depressed scars, but boxcar scars are generally not eliminated by subcision. Intradermal incision technique (intracision) can treat chicken pox scars by untethering fibrotic strands, raising collagen synthesis, and having additional intradermal blood pocket formation. We have found that chicken pox scars further improve when intracision is followed by laser skin resurfacing.
