RESUMO
BACKGROUND: Laser hair removal is one of the most popular aesthetic procedures. AIMS: The study aimed to assess the efficacy and safety of a novel applicator combining three wavelengths (1064 nm, 810 nm, and 755 nm) for hair removal. PATIENTS/METHODS: This prospective study included a four-session hair removal treatment with three wavelengths combined and emitted simultaneously using an in-motion technique. Patients were treated in eight-week intervals between each session and a follow-up of 3 months. RESULTS: Twenty-two men (mean age 41.5 years, SD = 6.1) were included: two (9.1%) Fitzpatrick skin type II, 19 (86.4%) type III, and one (4.5%) type IV. Treated areas were two abdomens (14%), fourteen backs (64%), and five thoraxes (23%). Hair characteristics were evaluated with a dermatoscopic imaging system. Three months after the last session, the mean decrease in the hair count was of 75.6% (SD 5.9) (p < 0.0001), in hair density of 75.6% (SD 5.9) (p < 0.0001), in the terminal hair number of 60.1% (SD 55.0) (p < 0.0001), and in the vellus hair number of 39.7% (SD 72.9) (p = 0.0001). CONCLUSION: The combined three different wavelengths in a single device provided a wide range of absorption and penetration, allowing for a safe and effective treatment.
