Abstract: This invention discloses an apparatus for skin treatments. The apparatus comprising a chamber placed on a skin target which is formed with an aperture on the distal end thereof; means for applying vacuum to said chamber, therefore the skin target is able to be treated upon the applied vacuum; and/or means for supplying negative ion into said chamber; and c) at least one light source with one wavelength or multi-wavelength, wherein the light source is arranged inside the chamber to provide optical energy in the predetermined wavelength(s) through the aperture to the skin target. With the assistance of negative ion as well as vacuum, the skin treatment will be improved because it purifies the air and relieves stress to enhance activation of skin cell, accelerate blood cycle.
