The process of microdermabrasion involves micro crystals being sprayed onto the skin to gently remove the outer dead skin cells. The procedure is gentle enough to do without any topical numbing and is often combined with a light chemical peel. Microdermabrasion can be done on various areas of the face and body to improve the texture of skin, stimulating collagen production. It works especially well to improve conditions such as mild scarring, stretch marks and aging skin.
