Abstract
Objective: To evaluate the reduction in unwanted body and facial hair at various body sites of Fitzpatrick skin types I–III and the efficacy, comfort and safety of this treatment intended for home-use by the general public. Methods: In this non-randomized study, 29 individuals were given three sequential weekly treatments on a total of 31 body and facial areas including the axilla, bikini area, abdomen, neck, chin and upper lip using a novel intense pulsed light device. All participants completed a simple self-assessment questionnaire, as well as an evaluation of pain/discomfort. Results: The mean reduction in terminal hair counts was 47% at 4 weeks' follow-up and 41% at 6 months' follow-up after completing three sequential weekly treatments. Overall, 84% of participants showed a significant percentage of hair reduction (p<0.01) at the 6-month follow-up, with a mean of 51% (range 25–86%). No treatment-related side effects were reported, with little or no discomfort reported during the treatment. Only mild erythema was noted immediately post-treatment. In total, 85% of the participants were either pleased or very pleased with the results 1 month after the third treatment. Conclusions: In simulated consumer use, this home-use IPL demonstrated a significant, quantifiable and sustainable reduction in unwanted body and facial hair with minimal side effects.
