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. The scrub is followed by an application of high-quality lotion or cream that leaves your skin hydrated. A body scrub 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.)A scrub works in a few ways: As you massage it over your body, the exfoliating granules help to slough off dead skin, and the rubbing action itself boosts circulation and helps drain your lymph nodes, by increasing blood flow to the skin’s surface.
