Randomized study of tolerance and efficacy of a home-use intense pulsed light (IPL) source compared to the hot-wax method

Summary Background More and more we are seeing depilatory mechanisms based on IPL technology and used at home. As far as we know, these appliance have not undergone either safety or efficacy testing. Aims The aim of the study was to compare tolerance and efficacy of two depilation methods a medical device in‐home‐use IPL (E‐One) and hot wax. Materials & Methods Axillae of 63 persons were treated by either IPL (intense pulsed light) or hot wax for 49 weeks. Tolerance was assessed clinically by a dermatologist and efficacy by an independent blinded photographic assessment. Results Tolerance of the two methods is reasonably good with better results for the IPL treatment. IPL treatment is also much more efficient. Conclusion This study confirmed good tolerance and excellent efficacy of this first one medical device used at home. Taking into consideration the mechanical action of the IPL and our experience, other cutaneous appliances (against wrinkles (or aging), hyperpigmentation. etc.) could be considered after optimization of the technical parameters.
