Split-face comparison study of cryogen spray cooling versus pneumatic skin flattening in skin tightening treatments using a long-pulsed Nd:YAG laser.

Background. Nd:YAG pulsed lasers are used for non-ablative skin tightening treatment. A common drawback of this procedure is pain, which is often intolerable. Pneumatic skin flattening (PSF) is a new technology which alleviates pain in laser treatments. The purpose of this study is to assess the clinical efficacy and pain reduction in Nd:YAG laser skin tightening treatments with PSF compared to Nd:YAG laser skin tightening treatments with cryogen spray cooling (CSC). Methods. Eleven patients were treated on the face with an Nd:YAG laser operated at an energy setting of 30 J/cm更多
