Background:Hirsutism means excessive terminal hair growth in a female in male pattern distribution. Perception of hirsutism is subjective. Permanent laser hair reduction is a slow process taking many sessions and tracking of improvement parameters is tedious. Hence, a lot of confusion still exists regarding the type of laser most beneficial for treatment.Aim:The aim of this study was to compare the effectiveness and safety profile of long-pulsed Nd: YAG laser (1064 nm) and intense pulse light (IPL)-755 nm in management of idiopathic facial hirsutism.Settings and Design:Open-labelled, randomly allocated experimental study.Subjects and Methods:The study included 33 cases of idiopathic facial hirsutism. Patients were randomly divided into Group A, treated with long-pulsed Nd: YAG laser and Group B, treated with IPL-755 for a total of six sessions at 1 month interval.Statistical Analysis:Chi-square test was used in Medcalc® version 9.0 and the test of significance was taken to be P < 0.05.Results:Average percentage of improvement in Group A, according to patients at each sessions were 46.33%, 70.66%, 81.66%, 84.67%, 85.33%, 87.33% and that in Group B were 28.06%, 39.72%, 52.22%, 64.72%, 67.78%, 71.11%, respectively. Excellent response (>75% reduction in hair) after six sessions in Group A was seen in fourteen (93.33%) out of fifteen patients, whereas in Group B, it was seen only in three (16.66%) out of eighteen patients. In Group A, erythema was seen in 26.67%, perifollicular edema and hyperpigmentation in 13.33% each. In Group B, erythema was seen in 50% patients, perifollicular edema in 16.67% and hyperpigmentation in 38.89% patients.Conclusions:Long-pulsed Nd: YAG Laser (1064 nm) is better than IPL-755 nm in terms of safety and effectiveness in the management of idiopathic facial hirsutism.
