The facial appearance during healing is unpleasant, and the complication rate is high. objective. We evaluate a Q-switched Nd:YAG laser operating at 1320 nm, with a cryogen delivery system and a skin temperature sensor. The system cools the target skin, followed by the laser impulse which passes through the cooled epidermis into the dermis. methods. Ten patients are presented.
