Objective To explore the effect and complication of diode laser and long-pulsed alexandrite laser for hair removal in different skin type.Methods A total of 1061 patients (1741 sites) were divided into 2 groups by skin type:one group were treated with diode laser,with wave length of 810 nm,and pulse width of 400 ms,with 12 mm × 10 mm spot size; another group were treated with long-pulsed alexandrite laser,with wave length of 755 nm,of pulse width of 20 ms,with 12.5 mm spot size,50-60 days intermitted between each treatment.Results The effect of hair removal by two lasers in different skin type was without divergence,but to darker skin,complication was lower when treated by diode laser.Conclusions The effect of hair removal by two lasers in different skin type is similar,but diode laser on hair removal is much safer to dark skin.
