Combination of short- and long-pulsed mode of electro-optical synergy technology for photoepilation: A retrospective study with short- and long-term follow-up

Abstract

The dual-energy technology of ELOS showed promising results for photoepilation of dark as well as blond and white hairs; however, only few studies exist on this topic. Objective To assess the short- and long-term effect of an electro-optical synergy device for photoepilation. We carried out a retrospective study on 24 patients with unwanted facial hair. Each area was treated consecutively with two passes using a combined-energy system [intense pulsed light (680-980 nm)/bipolar radiofrequency]. The short-term results were assessed semiquantitatively by three independent dermatologists based on photographs taken before and after treatment; evaluation of long-term results was based on a telephone questionnaire. After a mean of 5.2 treatments and 3.2 months follow-up, 22.2% of the treatment areas showed no/poor clearance, 28.9% moderate, 46.7% good and 2.2% excellent. Similar results were seen in thin and thick hair as well as fair and dark hair. After a period of 2 years, eight patients were satisfied with the results and did not wish any further treatment. Ten patients continued treatment with an electro-optical synergy device: After an average of 3.6 sessions, 70% of them were satisfied with the results. Five patients ceased treatment because the success did not meet their expectations. Two passes with this combined-energy system are an effective treatment option for the removal of thin, thick, fair and dark hair; however, the system has no significant advantages over other available methods of photoepilation.
