Skin Brush. Most people don’t realize that the skin is the largest organ in the body and in turn is responsible for about 20% of the detox process. Therefore dry brushing helps exfoliate and unclog by removing the dry skin, revealing the new layer of clean, bright and smooth skin which the body processes every 12 hours. If it is done often, the skin will be seen as glowing and healthy. Skin brushing is an easy activity to add to your daily routine. Remember after skin brushing, shower as usual and massage some good moisturizer into your skin.
