HIFU targets deep down in the foundation layer of your skin, the same layer addressed in cosmetic surgery. Unlike lasers, which penetrate the skin from the outside in, the HIFU procedure bypasses the surface of the skin, and delivers targeted energy specifically into the deep, structural tissues and muscles where collagen lives.
HIFU involves penetrating ultra-sound energy to stimulate collagen productionin the deep dermal and sub dermal levels, which results in micro injury to that tissue. As the tissue heals, it increases collagen and as the collagen fibers organize and shorten, a tightening effect is seen on the skin.
