Not only does coffee perk you up, but it can serve as a potent exfoliant as well, provided that you rub the ground-up coffee beans on your skin instead of using them to brew a steaming cup of joe. It helps tone the skin as well. Jennifer Frederick, spa director at Ritual Salon and Spa in Las Vegas, Nev., recommends using it as the main ingredient in a body scrub. Mix two cups of coarsely ground coffee with a cup of sea salt and two-to-three tablespoons of massage oil. Take a hot shower to moisten your skin and open your pores, and then, using wide circular motions, rub the mixture onto your skin with strong, even pressure. Then rinse off the scrub, pat the skin dry with a towel and apply your favorite lotion. A similar treatment would cost you $80 to $95 at a spa.
