Hair removal with a combined light/heat based photo-epilation system

Abstract

BACKGROUND: A variety of lasers and light sources have been used for removal of unwanted hair. A novel, new, flashlamp–based device, with a mechanism of action based on a combination of both emitted light and heat, has been developed for safe and reliable hair removal. OBJECTIVE: To assess the efficacy and safety of hair removal by a combined light heat based photoepilation system. METHODS: A pilot trial was undertaken. Twenty one anatomic sites received one to three treatments with the SpaTouchÁ light heat based photoepilation system. Fluences ranging from 6.25 to 6.45 J cm 2 and pulse duration of 35 ms were used. Evaluations of hair regrowth was performed at 4 months after the last treatment by comparing the terminal hair count to the baseline values. Patient satisfaction and potential complications were evaluated. RESULTS: Average hair reduction after photoepilation was 27 for one to three treatments at 4 months following the final treatment. 46 and 15 of subjects reported being ’mildly pleased’ and ’very pleased’ with the results of treatment. No hyperpigmentation, hypopigmentation or scarring was observed at 4 months after treatment. CONCLUSION: The SpaTouchÁ light heat based photoepilation system represents the newest efficient and safe method in hair removal. Further study of optimal parameters is required.
