Like the surface of the earth, the majority of the human body is comprised of water we can’t drink. Skim the debris from your skin’s surface with today’s Groupon: for $50, you get a microdermabrasion treatment at Avanti Medical Spa in St. Augustine (a $100 value).

Avanti Medical Spa sloughs spent skin with rejuvenating spa services and tranquilizing treatments. During the microdermabrasion treatment, an experienced aesthetician uses a small handheld device to evict squatting skin cells from their tissued tenements. Fine micronized crystals gently loosen the dead skin, while the adjustable suction vacuums up any evidence of the epidermal expunging. The one-hour procedure may increase the effectiveness of skin-care products by up to 50%, and has been known to reduce the appearance of fine lines, wrinkles, mild acne scars, and confounded facial expressions.
