Introdution: Many different laser systems are available for permanent reduction of unwanted hairs; however, no single laser has been shown to be superior in providing safe and effective hair removal in all skin types. The objective of the study was to evaluate the efficacy and safety of long-pulsed Neodymium-doped Yitrium Aluminium Garnet (Nd:YAG) 1064-nm laser along with cooling device for hair removal in darker skin types. Materials and methods: A total of 85 female patients of Fitzpatrick skin types IV and V with terminal facial and/or non-facial hairs were treated with a long pulsed Nd:YAG laser 1064-nm, (6mm spot size, fluence of 60-100J/cm2 with pulse width of 40 or 60msec and 10-mm spot size, fluence of 36-45 J/cm2 with pulse duration of 15msec. 6 or more consecutive laser treatments were delivered to 160 skin sites at an interval of 6 to 8 weeks. Both the outcome and the adverse events were noted down. Results: There was a significant hair reduction of 60-80% after 6 treatment sessions. Non facial sites like axillae and chest responded slightly better than facial sites. Amongst the facial hairs, side burn showed more reduction than chin and upper lip. Adverse reactions were minimal and included mild pain, transient erythema, perifollicular edema and rarely post inflammatory hyperpigmentation without scarring. Conclusion: The long-pulsed 1064-nm Nd:YAG laser is a safe and effective method of hair reduction in patients of dark skin types. It may require more than 6 sittings to have permanent hair reduction. Side effects were limited and transient.
