Having manicured hands makes for more impressive handshakes, but having pedicured feet allows for dazzling footshakes across nonstop knitting circles. Be doubly cordial with today's Groupon: for $40, you get a Shellac manicure (a $25 value) and pedicure (a $55 value) at Lua Nail Bar in Exton (an $80 total value).

The cuticle curators at Lua Nail Bar nourish appendages with skillful caretaking and natural ingredients. The Lua signature manicure and pedicure lets hands and feet imbibe the hydration of green-tea leaves and a green-tea aloe-vera mask, and tea-tree oil exhilarates extremities as much as listening to someone count past 20. Hot towels and hot stones cloak tight muscles in steamy warmth, and a paraffin dip coats phalanges with a final dose of moisture.

Crowning newly relaxed digits, nails are treated to trimming, filing, buffing, and tinsel strewing before cuticles are nudged back to make room for incoming nail strengthener and polish. Shellac polishes are polymer-based, shielding nails with up to two weeks of unchipped and unsmudged color. The entire spectrum of Shellac pigments is also “3-free,” barring their contents from the invasion of formaldehyde, toluene, and DBP. Inside Lua's ultrasoothing spa space, palms brush against rough-hewn stone walls, noses smell the sweet exhalations of fresh flowers, and freshly pedicured feet pad across timbered floors on their way to cast fresh air into stodgy tap-dancing competitions by performing confidently barefoot.
