Multiple lasers and intense pulsed light sources have been shown to provide long-term hair removal; however, the management of all dark skin phenotypes and light-colored hair remains problematic. The present study examined the long-term photoepilatory effect of a combined intense pulsed light (IPL) (680-980 nm)/radiofrequency (RF) (10-30 J/cm3) light source and its efficiency for the treatment of multiple skin phenotypes and varied hair colors.


Forty adult patients (skin phenotypes II-V) with varied facial and non-facial hair colors were treated with a combined IPL/RF technology. Four treatments were carried out over a period of 9-12 months at 8-12-week intervals. Light energy ranged from 15 to 26 J/cm2, while RF energy varied from 10 to 20 J/cm3. Hair counts and photographic evaluation of skin sites were obtained at baseline, and months 1, 3 and 5 after the final treatment session. H&E biopsies were examined at 1 week in five randomly selected study cohorts.


Maximum hair reduction was observed at 6-8 weeks after each treatment. An average clearance of 75% was observed in all body locations at 18 months. No significant adverse sequelae were reported. Results showed no significant dependence on skin color: lighter and darker skin types responded similarly to treatment. Histologic evaluation revealed thermal damage to hair follicles with vacuolar degeneration.


The combined IPL (680-980 nm)/RF light source with contact cooling is a safe and effective method of long-term hair reduction in patients of diversified skin types and varied hair colors and is associated with excellent patient safety.
