Bath Scrubs exfoliate, detoxify, and moisturize the skin, providing antioxidant, healing, and hydrating benefits. Skin exfoliation removes dead skin cells, leaving your skin feeling soft and polished. Skin exfoliation is great to do before applying a self - tanning product since the surface of your skin will be smooth and receive the tanning product more evenly. For a really close shave, try using a body scrub before shaving.
