Abstract
A dermatologic hair-regrowth-inhibiting apparatus is disclosed which is cordless and sufficiently compact as to be hand-held. A self-contained housing is configured for gripping by a person's hand for cordless manipulation in a hair-regrowth-inhibiting procedure. A light source and electrical circuit are contained within the housing. The circuit includes one or more batteries for energizing the light source to produce output light pulses. A light path within the housing includes an aperture through which eye-safe light pulses are propagated out of the housing having properties sufficient for at least temporary hair-regrowth inhibition. A diffuser is disposed along the light path to reduce the integrated radiance to an eye-safe level.
