This paper is intended to outline the current thinking regarding the process involved in depilation by pulsed ruby laser. The key laser parameters of wavelength, pulse duration, energy density, spot size and spatial profile will be discussed together with their impact on the outcome of the procedure. A parallel series of clinical trials have been carried out in a number of centers on both medical complications of hair growth and the cosmetic use of the technology. The results of these trials detail the efficacy of the treatment as well as the incidence of side-effects or complications.
