DIAMOND MICRODERMABRASION, exfoliating the top layer of dead skin. In crystal microdermabrasion the outermost layer of dead skin is abraded with a hand-held device that emits a strong blast of aluminum oxide crystals onto the skin. Because of this stream it is important to avoid the areas around the eyes and mouth. In Diamond microdermabrasion, dead skin cells are exfoliated and suctioned off the face with a machine using  tips covered in tiny diamonds. The diamond tips together with the strong suction—make it possible to exfoliate the skin more thoroughly. Adjustable suction levels can increases blood flow to the skin, in turn helping to produce collagen.There is less likelihood of particles getting into the eyes or mouth and is regarded as an especially safe form of treatment. Effective on deep acne scars or old stretch marks.
