The crystal deodorant's effectiveness is based on its antibacterial properties: it kills the bacterial strain of sweat so that sweat does not smell. The crystal deodorant does not interfere with the skin pores' normal function (support the sweat glands, etc.) but is a natural and inexpensive choice as a deodorant. You can also use the antibacterial crystal deodorant to disinfect insect bites and post-shave wounds.
