A body scrub is a popular body treatment that is basically a facial for the body: it exfoliates and hydrates your skin, leaving it smooth and soft. A body scrub is done with an abrasive material -- usually sea salt or sugar -- mixed with some kind of massage oil and an aromatic like essential oils. If the scrub uses salt, it might be called a salt scrub, salt glow or sea salt scrub.
The scrub is followed by an application of high-quality lotion or cream that leaves your skin hydrated. This is not technically a massage because body treatments can be performed by estheticians, who are only licensed to work on skin, not the underlying muscle tissue (unless they are giving massage to the face, neck, and shoulders.)
