    Abstract: Objective To investigate the efficacy of melasma treated by Medlite C6 Q-switch Nd:YAG laser.Methods 120 melasma outpatients were treated by Medlite C6 Q-switch Nd:YAG laser with 1064nm wavelength, 6mm spot, 2.5～3.5J/cm2 energy. The clinic efficacy and adverse effect were recorded.ResultsAmong the 120 patients, 43 cases (35.8%) with melasma were disappeared completely, 68 cases (56.7%) regression obviously. The total efficient rate reached 92.5%. All patients skins feeled more better texture, smooth than that before treatment. No severe adverse reactions were seen. Conclusions Medlite C6 Q-switch Nd:YAG laser with low energy and large spot is an effective and safe option for the treatment of melasma. ......
