Since gaining popularity in the late 1990s, microdermabrasion has become a staple of the skin rejuvenation industry. A crystal-free method of microdermabrasion, called diamond tip, was introduced as a non-invasive, hygienic alternative to the original method. A technician removes dead skin cells by sweeping a wand encrusted with synthetic or genuine diamond chips over the surface of the skin. This encourages cell metabolism, which accelerates the growth of healthy, glowing skin.
