Microdermabrasion is a light cosmetic procedure that uses a mechanical medium for exfoliation to gently remove the outermost layer of dead skin cells from the epidermis. Most commonly, microdermabrasion uses two parts: an exfoliating material like crystals or diamond flakes and a machine based suction to gently lift up the skin during exfoliation. It is a non-invasive procedure and may be performed in-office by a trained skin care professional.^[3] It may also be performed at home using a variety of products which are designed to mechanically exfoliate the skin. Many salon machines and home-use machines use adjustable suction to improve the efficacy of the abrasion tool. Recently, cosmetic scrub products that contain fine grit made from the pits of various fruits and from other materials are using the term microdermabrasion in their marketing.^{[citation needed]}
