Background: Phototherapy of photoaged skin has been attempted by lasers or intense pulsed light at the visible or near-infrared part of the spectrum. The use of red Light-Emitting Diodes (LED) delivering a low dose energy to the skin has been described for office and home use. Methods: In the present study, a portable home-use device is presented that combines fractional non-thermal red LED with mild contact heating. Forty subjects aged 30 - 55 presenting with facial lax skin, large pores, fine lines, wrinkles and brown pigmentation received 8 bi-weekly treatments for 4 weeks, using the Silk’n Reju/FaceFX device (Home Skinovations, Yokneam, Israel). Skin condition was evaluated before and 1, 2, and 3 months following the last treatment session. Grading of outcome was done according to an independent blinded evaluator and patient satisfaction. Results: Facial skin improvement of wrinkling and skin texture were apparent immediately and scored clinically after 3 months as excellent and considerable by >90% of patients. Pigmentation improvement was less apparent. Overall facial skin improvement was noted by 77% of patients. Conclusions: The combination of fractional red LED and mild contact heating, using an at home portable device, proved to be safe and effective method to improve the quality of photoaged skin.
