Objective To evaluate the efficacy of Q-Switched Nd:YAG laser 1,064nm for the treatment of  melasma.


Methods A total of 100 patients were included in this study. Treatment area was cleansed and Q-Switched Nd:YAG laser 1,064nm, was delivered with settings of 3mm spot size, energy fluence ranging from 500-700 joules and repeated frequency at 6 Hz. Clinical response was assessed by MASI score.


Results A total of 100 patients were included in the study. Mean age of the patients was 31.18±5.51 years. There were 13 males (13%) and 87 females (87%). Mean duration of disease was 1.99±0.88 years. Type of melasma was as follows: epidermal 47 (47%), dermal 31 (31%) and mixed 22 (22%). Q-Switched Nd:YAG laser 1,064nm for the treatment of  melasma was effective in 59 patients (59%).


Conclusion 1064nm Nd:YAG laser was safe, effective and well-tolerated by all patients.
