Background: Laser has been long accepted as a solution for excess or unwanted hair growth yet traditional lasers are not always ideal for safe and effective outcome for all skin types and hair characteristics. A diode laser module combining three wavelengths (755, 810, and 1064 nm) in a single pulse was developed to provide a fast and long‐term solution for subjects with various profiles. Aims: To evaluate the safety and efficacy of a Triple wavelength diode laser module for hair removal treatment in all skin types (Fitzpatrick I–VI). Subjects and methods: This was a prospective, dual centered, single‐arm study. Subjects were treated with a novel diode laser module. Thirty‐six subjects were enrolled, sixteen with Fitzpatrick skin types I–IV (46%) and twenty with Fitzpatrick skin types V–VI (54%). Treatment areas were axilla and bikini lines. Subjects underwent 4 treatment sessions at 6 weeks ± 5 days intervals and attended a follow‐up visit 3 months after the last treatment session. 2D digital photographs were taken at baseline and at the follow‐up visit, and a hair count was conducted by three blinded evaluators. Results: A significant reduction in hair count between baseline and the 3‐month follow‐up visit was observed in both axilla and bikini lines for all skin types. The mean hair reduction was 41.5 ± 19.4% and 48.1 ± 20.9% in the axilla and bikini line, respectively. A significant hair reduction was also observed within skin type groups; mean hair reduction 45.5 ± 16.9% and 40.3 ± 17.2% in skin types I–IV and V–VI, respectively, indicating similar efficacy for both light and dark skin types. No serious adverse events were reported. Conclusions: This study demonstrates that the Soprano Titanium laser platform is safe and effective for hair removal treatment in all skin types.
