Efficacy and safety of triple wavelength laser hair reduction in skin types IV to V

Abstract

Background Laser hair reduction is one of the most common laser procedures in dermatology. Laser systems available are Ruby at 694 nm, Alexandrite (755 nm), Diode (810nm), and Nd:YAG (1064 nm). Recently, devices presenting a combination of wavelengths have shown to produce high effective hair reduction with no related risks. This study was conducted with the Soprano Ice Platinum (Alma Lasers, GMBH, Germany) that emits a combination of three wavelengths at 755, 810, and 1064 nm in a single pulse. Aims To establish the efficacy and safety of novel triple wavelength laser hair reduction technology in skin types IV to V. Patients and Methods This was an investigator initiated, single‐center, prospective clinical study conducted between December 2017 and June 2019 with a total of 25 patients (23 female and two male) above 18 years with skin types IV and V, areas included are face, beard, neck, chest, and others. Results Hair reduction was assessed using the physician GAIS (global esthetic improvement scale) score: no results 0% reduction, poor 0%‐25% reduction, average 25%‐50%, good 50%‐75%, and excellent 75%‐100%. All 25 patients (mean age 28 years, range 18‐52 y/o) completed all six sessions of the study. Conclusion Objective clinical assessment of hair reduction using the physician GAIS score in 90 anatomical sites scores an excellent reduction in 95.5% areas and good reduction in 80% areas. This current study shows that a synergistic combination of three diode laser wavelengths used for hair removal (755, 810, 1064 nm) is effective and safe to use in subjects skin types IV and V for facial and body hair.

Novel laser hair removal in all skin types

“…All the reported side effects were transient and resolved within 2 days of onset. Furthermore, Raj Kirit et al 12 reported 76% hair reduction in the bikini area within 6 treatment sessions, and no adverse events were recorded throughout the study. The current study's results are comparable to those of previous similar studies.…”

“…This study presents the results of thirty subjects treated with combined laser wavelengths in the axilla and bikini line. Very few studies assessed hair removal in those area 12,13 . Khoury et al 13 showed 67.1 ± 15.1% of hair reduction in the axillary area.…”

“…Factors such as skin type and hair color, as well as different levels of hair thickness and depth, affect the appropriate laser selection 9–11 . Recently, devices presenting a combination of wavelengths have shown to produce high effective hair reduction with no related risks 12 . Novel diode laser systems combining three wavelengths (755, 810, 1064 nm) in a single pulse have been developed to target different structures of the hair follicle for the removal of unwanted hair and to provide long‐term hair reduction suitable for diverse hair varieties and all skin types.…”

Triple wavelength diode laser for hair removal: A perspective

“…Recently, it has been shown that laser device with combination of wavelengths produces effective results in hair reduction without significant increase in risks. [11,12] Triple wavelength laser combines the synergy of three wavelengths 1064, 810 and 755 nm. Out of these three, 1064 and 810 nm have potential for deep penetration and hence focus on darker skin tones.…”

“…Out of these, one study is prospective and other is retrospective. Kirit et al [11] have recently published their results of investigator initiated prospective study evaluating efficacy and safety of triple wavelength laser for hair reduction in 25 adult patients with skin types IV and V. e investigators used the Soprano Ice Platinum (Alma Lasers, GMBH, Germany) with the combination of three wavelengths at 755, 810, and 1064 nm. ese three wavelengths are emitted in a single pulse.…”
