Abstract
A method for removing hair from a skin surface includes removing protruding hair fibers from a skin surface in a plurality of temporally spaced treatment sessions by a process other than application of light energy. In each of the treatment sessions, one or more light pulses are applied to the skin surface to enhance the removal of hair by the process. The pulses are characterized by pulse parameters including radiation wavelength such that light of the pulses is absorbed by the hair fibers below the skin surface. The pulses are applied to the skin surface in the absence of an exogenous chromophore on the skin surface and the hair fibers along the skin surface. A hand held device includes a pulsed-light applicator and a cutting edge.
