While scented sprays and targeted serums have made body care cool, salt scrubs are still a mainstay for those seeking soft, smooth arms and legs. That’s because they’re supereffective — they use a gritty texture to manually buff dead cells off the surface of your skin that could otherwise pile up, contributing to a dull appearance or even body breakouts. Plus, they can help with “improving circulation, detoxing due to the minerals, and possibly improving tone and texture, depending on the other ingredients included in the scrub,” says Sheila Farhang, a dermatologist in Tucson, Arizona.
