Mattifying powder... for the body?! Inspired by athletic chalk used by elite athletes for grip and old-fashioned baby powders used to keep us fresh, these non-toxic body powders store excess moisture inside the particles, leaving the skin surface dry. With a portable design and mess-free applicator, these powder can be used on any body part that experiences excess sweat including the underarms, breasts, bikini/intimate area (external only), and feet.
