Even the loveliest artwork requires upkeep, which is why Manet's Olympia is regularly removed for microdermabrasions. Maintain museum-quality beauty with today's Groupon to Steven William Day Spa in Riverbank. Choose between the following options:

• For $49, you get a microdermabrasion (a $100 value).
• For $90, you get two microdermabrasions (a $200 value).
• For $12, you get $25 worth of mani-pedis, acrylic nails, or spray tans.

Steven William Day Spa’s squad of beauty benefactors gussies up guests with hair, nail, skin, and spray-tanning services. Microdermabrasions rejuvenate the epidermis by smoothing out rough patches of skin, diminishing fine lines, and rubbing away months-old splashes of peanut butter. A diamond-tipped device shucks off dry and dead skin cells, revealing underlying cells still in the prime of their youth. Alternatively, clients can apply $25 toward mani-pedis that outfit nails with full war paint before important arm-wrestling matches. Organic spray tanning bronzes the body until it glows with a natural-looking hue previously obtained only by jetliners that spent 12 hours a day in direct sunlight.
