Saltea - Sea salt scrub. Benefit #1 – Skin Glow One of the biggest benefits to body scrubs, particularly the salt scrub, is the glow that your skin is left with. There are different grades of salt, and sea salt is the best option for a salt glow. The results for your body will depend on the type and grade of salt you or your spa technician uses. Unlike refined salts, the preparation of sea salt usually includes very little processing, so it retains its moisture and mineral treasure.
