Your skin is actually a complex organ performing many vital functions. Hundreds of thousands of tiny sweat glands act not only as the regulators of body temperature but also as small kidneys. They cleanse the blood and free the system from health threatening poisons. If the skin becomes inactive arid its pores clogged with millions of dead cells then the uric acid and other impurities remain in your body, overworking the kidneys and poisoning the whole system. Dry brush massage opens the pores and cleanses the skin allowing toxins to escape.
