A phototherapy mask uses optical fibers coupled to LEDs to irradiate a treated epidermal skin area on or around a person's face with specific wavelengths of light in selected dosages (J/cm2). Peripheral configuration of LEDs on the mask eliminates problems of heat dissipation, and multi-mode optical fiber is employed for diffusion of light uniformly over the treated epidermal skin area.
