Dry skin brushing helps stimulate lymph and blood circulation to remove toxins and waste through the skin. It clears stale sweat and secretions to allow fresh sebum production and toxin elimination while preventing pore blockage. As the lymphatic system lacks a pump, dry brushing aids its flow to dump toxins through the skin. It also encourages cell renewal by removing dead outer skin cells and improving surface skin circulation more than soap and water alone. The technique involves brushing with a natural bristle brush from the feet up and towards the heart to stimulate lymph and blood flow back to the heart.
