<p>A skin treatment laser device suitable for home use. The device includes an array of at least two types of laser units. A first type of laser units operates at a wavelength chosen to heat the skin generally and a second type of laser units operates at a wavelength chosen to produce tissue damage in extremely small and separated regions of the skin. No skin damage occurs in tissue surrounding the regions of skin transformation or destruction. Natural healing processes originating in the surrounding tissue heal the damaged tissue and produce general rejuvenation effects in the skin tissue. Laser beams from at least the second type of laser units are focused into the small regions to be damaged. A preferred focusing technique utilizes cold sapphire cylindrical rods. Preferably, the skin to be treated is shaved or abraded prior to or simultaneously with the laser treatment to remove portion of the stratum corneum so to improve laser beam penetration. In preferred embodiments the device includes shaving blades so that skin hair and or a thin layer of skin can be removed simultaneously with the laser treatment. In other embodiments an abrading feature is included. Uses include skin rejuvenation and hair removal.</p> |
