N2 - The purpose of this study was to analyze treatment effect for skin aging accordin g to changes of fluence and pulse duration of 1064nm Nd:YAG laser. For this purpose, we designed skin model composed of epidermis, dermis, and fat, and each layer had similar thi ckness of facial skin. Environmental temperature was set to 26°C, and the initial temperatur e of each skin layer was designated as human body temperature (36.5°C). The fluence of t he treatment laser was divided into 8, 9 and 10J/cm2, and the pulse duration was classified to 0.35, 0.50, 0.70 and 1.00ms, respectively. Based on experimental results, we found that t he skin temperature increased along with penetration depth as increase in fluence. In additio n, the treatment condition with fluence of 8J/cm2 and pulse duration of 0.7ms, as well as fluence of 9J/cm2 and pulse duration of 0.5ms, transmitted the heat into the dermis most ef fectively without any skin damage.
