ABSTRACT
Objective To evaluate the efficiency and safety of hair removal in different areas with Lightsheer Duet diode laser and to compare clinical effect and safety in axillae hair removal between the two models,high-speed and standard model.Methods Lightsheer Duet diode laser was used to remove hairs from different areas in 200 cases,for 4-8 weeks treatment 1 time,4 times for 1course.The curative effect and adverse reaction were observed after the treatment.Thirty axillae hair removal subjects were chosen randamly and received treatments using the different models,high-speed hand piece on one side and the standard hand piece on the other side.Hair removal efficiency and the immediate pain were compared and evulated on each subject.Results The hair was significantly reduced after 4 times treatments in 200 cases.The total effective rate was 95.54 ％ and positively related with the treatment times.Pigmentation was found in 3 cases,but it disappeared after 1-3 months.The total effective rate was 100 ％ after the 3 times treatments in axillae hair removal subjects both using the high-speed model or the standard model in 30 cases.There was no statistical difference between the two models except less pain in the high-speed model.Conclusions Lightsheer Duet diode laser is a safe and efficient method in hair removal.The high-speed model has more advantage on speed and causing pain.
