Clinical efficacy of 1 064 nm/755 nm dual wavelength laser on hair removal / 中华医学美学美容杂志

ABSTRACT

Objective:To evaluate the clinical efficacy of 1 064 nm/755 nm dual wavelength laser on hair removal.Methods:A total of 60 patients aged 18-52 (30±7) years in our hospital from January 2017 to December 2017 were collected. 1 064 nm and 755 nm laser hair removal was performed at the same symmetrical areas or two different areas in the same patient. We performed 6 sessions of laser treatment at 6-week intervals and the effect was evaluated 6 weeks after the last session.Results:The hair removal efficacy was 96.7% (58 cases) at 1 064 nm, 96.7% (58 cases) at 755 nm laser treatment. There was no significant difference in the effective rate between two wavelengths laser hair removal methods ( P>0.05). The incidence of pigmentation was 1.7% (1 case) at 1 064 nm laser and was 3.3% (2 cases) at 755 nm laser without significant difference ( P>0.05). No hypopigmentation, blister or scar appeared in all patients. The total satisfactory rate was 95.0% (57 cases) at 1 064 nm, 98.3% (59 cases) at 755 nm laser treatment, respectively. Conclusions:1 064 nm/755 nm dual wavelength laser has definite therapeutic effect and safety on hair removal.
