This Sol De Janeiro Brazilian Bod Buff Smoothing Scrub 'N' Mask ($25) handily does double duty as both an exfoliating scrub and a detoxifying mask. If you're looking to get rid of dead skin, polish it off with tiny bits of Brazilian quartz crystal, volcanic pumice, and grains of rice. But just know that those ingredients are all set in Amazonian clay . . . so, when you leave this treatment on for about 10 minutes before massageing it in and rinsing it off, you'll then reveal even smoother, softer skin underneath as a result.
