Efficacy of long pulsed Nd:YAG laser in the treatment of hirsutism

Introduction: Hirsutism is a psychologically distressing problem. Laser, do not provide permanent hair removal; but they are popular due to selective hair damage, decreased pain feeling, lesser time consumption, longer hair free interval and fewer side effects. Aim: The aim of our study was to evaluate efficacy and safety profile of Nd:YAG laser in the treatment of hirsutism. Materials and Methods: Forty females of age 18-35 with hirsutism were included in our study. Each patient was examined and their skin type noted and hirsutism graded according to Ferriman–Galleway score. Four sessions with Nd:YAG laser were delivered to all patients at 4 to 6 week intervals. Photographic evaluations and percentage of hair reduction was done before each session and final assessment noted at 6th month. Results: Thirty two patients completed all treatment sessions. Good hair reduction (50-75%) was seen in 28 patients after first treatment session. After 3 sessions, excellent hair reduction (>75%) was noted in 10 patients and good hair reduction in 18 patients. At 6th month, excellent hair reduction was seen in 12 patients and good response was noted in 16 patients. Side effects noted in our study were post procedure erythema and perifollicular edema (50%). Conclusion: The results of this study support safe and effective use of long-pulsed, 1064 nm Nd:YAG laser for hair removal in Indian patients.
