Dry Brush - Energy, with Detachable Head The plastic-free Ionic Brush is excellent for body exfoliation. Regular use of the Ionic Brush promotes blood circulation and sustainably tightens your skin. The brush can boost energy levels and assist the lymphatic system in detoxification. The friction of the fine bronze bristles (copper-tin alloy) generates negatively charged anions on the skin, which balance the existing positive ions on the skin. The energetic balance improves energy supply.
