All hands and feet require regular maintenance, except for permacured toes and the Hamburger Helper glove, which is immortal. Take care of what you actually have with today's Groupon at The Grotto Spa, located inside the Hilton Garden Inn on South Avenue in Staten Island. Choose between the following options:

• For $13, you get a signature manicure (a $36.58 value).
• For $20, you get a signature green tea pedicure (a $47.03 value).

The Grotto Spa burnishes bodies in a tranquil spa setting with a variety of soothing services, including delicate and rejuvenative hand and feet treatments. The 45-minute signature manicure begins with a gentle exfoliating scrub, purging paws of dry skin before a paraffin wax dip and warm mitts seal in metacarpal moisture. A lustrous finishing polish completes the treatment, leaving hands smooth, hydrated, and less likely to abandon wrists for the first sweet-talking mannequin they see. The 75-minute signature green-tea pedicure starts by soaking steppers in a green-tea bath to infuse hooves with antioxidants and natural healing qualities. Thorough massage and exfoliation prepares shoe-fillers for the green-tea mud wrap, which rehydrates the skin and paints over the geometric wrinkle-graffiti of time. A rich moisturizing-cream application caps off the rejuvenating pedicure, overwhelming feet with a feeling of satiny smoothness.
