Nail polish was invented around 3000 BC in ancient China—a fact that's doubly remarkable considering that human fingernails were only invented last year. Celebrate this admirable foresight with today’s Groupon: for $20, you get a classic manicure (a $35 value)—or, if redeemed Monday–Thursday, a classic manicure plus paraffin hand treatment (a combined value of $50)—at The Health Club & Spa at Fairmont Pittsburgh.

A luxurious 6,000-square-foot space, The Health Club treats fingertips and their attached persons with careful and beatific care. The classic manicure allows visitors to unwind in a vibrating barcalounger while the skilled 'curists deliver diligent reshaping of the nails. Care is given to the cuticles, and all proximate regions are revitalized through a sugar scrub, aromatic massage, and a finishing combo of vitamin C and avocado lipids. The spa staffers amplify the elegance by offering premium OPI nail polish and the opportunity to upgrade any services. Those who schedule their session Monday–Thursday will also pair up with a hand paraffin treatment that uses a rich wax infused with 11 essential vitamins, leaving the skin hydrated, soothed, and softer than a baby's dreams.
