810 nm diode laser for hair reduction with Chill-tip technology: prospective observational analysis of 55 patients of Fitzpatrick skin types III, IV,V

Abstract

ABSTRACTBackground: Various light based technologies like Diode, long pulsed Nd:Yag and Intense Pulsed Light are used commonly for long-term hair reduction. The commonest indication is hirsutism.Aim: 1. To evaluate efficacy and safety of 810 nm Diode laser in Fitzpatrick skin types III, IV and V.2. To assess percentage of cases on the basis of indications, average number of sessions, fluence required, the long-term results and complications using diode laser in darker skin types.Methods: A prospective observational study of 55 consecutive patients who came for laser hair reduction by 810 nm Light Sheer Diode laser with Chill tip technology was carried out. The sessions were conducted at an interval of 4–6 weeks and the patients were followed up over a period of 2 years. Data was analyzed using software SPSS (Statistical Package for Social Science. Ver.12, Inc. Chicago, USA).Results: Fifty-five patients (51 females and 4 males) were studied. 67.3% (n = 37) had skin type IV. The most common area treated was chin (n = 23). The average growth reduction of terminal hair at the end of three sessions was 61.25%. Only 8% (n = 4) had short-term side effects.Conclusion: Diode laser is highly effective for long-term hair reduction of terminal hair growth in Fitzpatrick skin type III, IV and V with no permanent side effects.Abbreviations: LHR (Laser Hair Reduction)
