Although outdoor tanning allows humans to absorb the sun's natural energy, the sapped star will eventually turn pale and suffer the fate of Earth's original sun, the moon. Save the sun with today's Groupon: for $10, you get one UV-free Mystic Tan spray tan at My Island Tan and Spa (up to a $29.99 value).

Nestled amid cheery yellow walls and calming greenery, the Mystic Tan MyMyst booth at My Island Salon and Spa mists skin with UV-free hues. Friendly technicians trained in the art of color customization help guests to choose shades that look natural on their epidermises or exoskeletons. After divesting itself of jewelry and clothing—swimsuit optional—the body basks in a gentle mist fortified with soothing aloe and the antioxidant powers of green tea. Powered by DHA and erythrulose, the spray summons bronze tones that range from light caramel to dark chocolate. Mystic’s MagneTan technology polarizes droplets, turning them into miniature magnets. This process then attracts them to the magnetic properties of the skin and convinces them to hug the physique evenly. Like the urge to don sweatpants during Thanksgiving dinner, the summery glow emerges after a few seconds and intensifies over the next 24 hours.

With proper care such as exfoliating before each session and moisturizing afterward, Mystic spray tans last about a week. For optimal results, clients should avoid showers and birdbaths for four hours post-spritz.

Though My Island Salon and Spa features discounted spray tans for members, today’s Groupon offers the best deal available for non-members.
