Although many Americans tend to go overboard, salt is essential for good health—at least 500 milligrams per day, according to the National Academy of Sciences. This essential mineral has a colorful history too; it influenced the development of cities and played a role in wars.
Salt is also a great addition to your skincare routine. Regular exfoliation with salt produces healthier-looking skin and aids the development of new collagen. Make an exfoliating scrub using sea salt by combining one part oil (such as sweet almond) and two parts sea salt to form a somewhat thick mixture. Rub liberally into your skin, then rinse.
