Recharge, energize and detox with The Copper Body Brush. As you dry brush, the friction created by the copper bristles floods your skin with beneficial negative ions. Abundant in nature, negative ions help to counteract the energy-draining effects of digital devices (which emit positive ions), while neutralizing free radical damage and supporting lymphatic flow. Copper dry brushing also promotes cellular turnover and supports collagen formation—leaving your skin looking firmer, smoother and more elastic. Note: These bristles are firm, so if you have sensitive skin, please use with care and perform a patch test first.
