Microdermabrasion is a skin-freshening technique that improves the appearance of the skin. The skin appears “brighter” after one or more treatments. The treatment is performed in the office setting. A device similar to a fine sandblaster is used to spray tiny crystals across the face. Gentle abrasion is mixed with suction to remove the dead outer layer of skin. As with other rejuvenation techniques, more than one treatment may be needed to achieve results. The skin may be a bit reddened or slightly irritated after treatment, but this usually subsides fairly quickly.
