Microdermabrasion is a modern technology that can be performed just about anywhere on your body, including the face, neck, chest, hands, back, elbows, and feet. Microdermabrasion is a mild abrasive blown onto your skin, which can help erase and smooth acne scars, sun damage, age spots, freckles, fine lines, scars, and rough skin. The procedure typically results in almost nil discomfort; many patients have described it as being very like having a "cat licking your skin."
