The ELTK HIFU ( High Intensity Focused Ultrasound) system functions to used focused ultrasound technology to provide a thermal effect on the skin which penetrates through the dermis to the superficial tendon membrane system. This allows for the a large amount of heat to be condensed in the specific location, which will result in a increased production in collagen in the skin. This will result in a effect of skin tightening and rejuvenation, with no down time for treatment. There are different size transmitters which are included in the system, each reaching a different depth of the skin. This system is an excellent option for any medical spa which is interested in adding on the newest non invasive technology for skin tightening of the face and body.
