An apparatus for laser depilation according to the present invention uses a semiconductor laser diode, which is controlled in respect of its energy level, thereby permitting an economical, effective and safe cosmetic treatment. The power output of light of the semiconductor laser diode ranges from 5 to 1500 mW, and the peak wavelength ranges from 600 to 1600 nm. The controller of the semiconductor laser diode comprises pulsating power output control means and radiation period control means for setting a desired length of time for radiation. With these control means the energy level of the beam of light from the laser may be so controlled that a strong beam of light may be thrown for a relatively short time, or that a weak beam of light may be thrown for a relatively long time. Thus, hairs of different thickness and colors can be removed. In parallel with projection of the beam of light from the laser air is sucked from or ejected toward a selected skin spot for treatment. When sucking the surrounding air, the selected skin spot is drawn toward the focus of the laser beam to improve the efficiency of treatment. When ejecting the air to the surrounding atmosphere, cooling is effected to improve the working efficiency of the laser. <IMAGE>
