This article provides an update on the contemporary use of the thermally confined micropulsed 1444-nm Nd:YAG interstitial fiber laser in the aging face and neck. Beginning with the concept that the use of Nd:YAG fiber lasers in aesthetic surgery is no longer limited to laser lipolysis, the article also covers the differentiating characteristics of the available Nd:YAG fiber laser wavelengths and laser tissue interaction and safety considerations when incorporating the use of these lasers into aging face surgery.
Keywords: Contouring; Facelift; Facial; Laser; Lipolysis; Neck; Thermal confinement; Thermal diffusivity.
