Micromdermabrasion is a skin-freshening technique that helps repair facial skin that reduces skin imperfections and the effects of aging (reducing fine lines). The licensed Esthetician uses a device like a fine sandblaster to spray tine crystals across the face, mixing gentle abrasion with suction to remove the dead, outer layer of skin. As with other skin rejuvenation techniques, more than one treatment may be needed to reduce or remove fine wrinkles and unwanted pigmentation.
