A dermatologic treatment device having a first light source emitting a first pulse of optical radiation beneficial to a dermatologic treatment, and a second light source emitting a second pulse of optical radiation and being optically coupled to the first light source. The second pulse enhances the brightness of at least part of the optical radiation in the first pulse upon impinging on the first light source. The dermatologic treatment device further includes a timing circuit adapted to energize the first and second light sources to at least partially overlap emission of the first and second pulses.
