background. Effective hair removal continues to pose a chal-lenge to the physician. The use of lasers represents a significant advance in epilation, but still requires further refinement. The long-pulsed Nd:YAG laser may offer advantages over other systems be-cause of its significant depth of penetration and minimal absorption by epidermal melanin, but ideal parameters need to be determined. objective. To evaluate the efficacy of a long-pulsed Nd:YAG la-ser system and determine the optimal parameters for hair removal. methods. Twenty-two subjects were treated with a cryogen spray-cooled long-pulsed Nd:YAG laser. Four adjacent sites were assigned to each subject, where the following sets of parameters were utilized: 50 J/c
