Microdermabrasion improves mild to moderate sun damage, scarring, wrinkles and other superficial skin problems. A gentle stream of tiny particles exfoliates the outer layer of skin and provides a fresh, glowing, younger appearance. The particles scrape away the surface layer of aging or damaged skin, which is then brushed off with the microdermabrasion vacuum tool with no need for anesthesia. Only a small amount of skin is removed, so sensitive areas such as the face, chest, neck, arms and hands can be treated. Results are comparable to a light chemical peel and should be immediately visible. Microdermabrasion is often performed in conjunction with other skin renewal procedures, such as laser treatment and chemical peels. Multiple treatments are recommended for full effect.
