Without regular care, people often lose confidence in their nails, letting high-fives become waist-level threes and jazz hands turn into manual Muzak. Show off proud digits with today's Groupon: for $37, you get a full set of gel nails at Carolyne Esthetics (a $75 value).

The skilled nail technicians at Carolyne Esthetics reinforce and lengthen natural nails with gel overlays. Like an extra-strength love potion, the gel manifests its powers into a transparent, lightweight formula that keeps hands from feeling cumbersomely decorated. The nonporous consistency adds to the gel's brawn, and it will also defy yellowing when exposed to the sun or other environmental triggers such as lemonade rain. Though the nails maintain flexibility, the method of adhesion resists lifting, ensuring long-lasting results and preventing wayward keyboard keys from squatting between phalangeal layers.
