A dermatologic treatment apparatus is disclosed which includes one or more housings with at least one housing configured for manipulation in a dermatologic treatment procedure, a light source, and an electrical circuit. The circuit energizes the light source to produce output light pulses. A light path includes an aperture through which eye-safe light pulses are propagated having properties sufficient for providing efficacious treatment. An optical diffuser is disposed along the light path to reduce the integrated radiance to an eye-safe level. The apparatus produces an output fluence not less than 4 J/cm2.
