If your skin seems dull, lifeless, or perhaps older than you'd like, a microdermabrasion treatment may give it an immediate lift. New, much healthier skin lies just beyond the surface of the old, dead surface skin, and microdermabrasion is an excellent technique to reveal it rapidly, without the danger of scarring or side effects. Microdermabrasion is a gentle exfoliation procedure that removes the outer layer of your skin, which contains dull, dead skin cells.
