Love means never having to say you're sorry, but beauty means never having to pause at stoplights. Shift your appearance into fifth gear with today’s Groupon: for $20, you get a 20-minute light-therapy session at Salt Cave (a $40 value). This Groupon expires in two months.

Salt Cave honors ancient healing traditions along with cutting-edge light-therapy technology to reduce wrinkles and imperfections on clients’ skin. The device bathes skin in a rosy polarized glow to jump-start cellular regeneration and games of red light/green light. By accelerating the healing process, the treatment can reduce the appearance of imperfections for more even-toned skin. Scars and cellulite begin to smooth out, and acne blemishes fade from view like a cowboy trotting his horse into a sandstorm. Light therapy can also work in conjunction with other treatments to accelerate healing for injuries such as flesh wounds and broken bones.
