Body scrubs are a mechanical exfoliant, meaning they physically remove dead skin cells from the outer layer of your skin with abrasive ingredients, like sugar or salt. This stimulates skin cell turnover, resulting in smoother, brighter skin and possibly preventing future acne breakouts. The primary function of body scrub for dry skin is to clear impurities and make skin feel soft and supple to touch. Just as much as you love your face, your body deserves all that pampering too.
