ABSTRACT
Objective To assess the efficacy and safety of 800 nm diode laser for removing unwanted hair of Ⅲ-Ⅴ skin type.Methods A total of 114 patients were treated with 800 nm diode laser on 234 sites.Four sessions were performed at an interval of 6-8 weeks.Percentage of hair reduction was evaluated 3 months after each session by comparing the terminal hair count to the baseline values.Follow-up was performed 6-8 months after the last session.In addition,subjective satisfaction of physicians and patients was evaluated according to a four-grade scale and the satisfaction rates were calculated.Results After fouth session,97.01% of patients had more than 40 % hair reduction,and 83.33 % patients had more than 60 % hair reduction.Hyperpigmentation was observed on 15 (6.41%) sites,and disappeared after 6-8 months follow-up.The satisfactory rates of the physicians and the patients were 98.25 % and 96.12 %,respectively,with no statistical difference (x2 =3.33,P>0.05).Conclusions 800 nm diode laser for removing unwanted hair of Ⅲ-Ⅴ skin type is a safe and effective treatment option for hair removal,with relatively less side effect.
