A body scrub's primary function is to remove dead skin cells through exfoliation as well as cleanse the skin and increase the body's blood circulation. If you're not using a body scrub then you're missing out on a number of benefits that other skin care products don't provide.
Essentially the benefits of using a body scrub are the removal of dead skin cells and impurities from the body, leaving you feeling fresh and your skin looking rejuvenated and revitalised.
Exfoliating dead skin cells removes the dull appearance of the skin. Humans shed skin cells daily and it usually takes about a month before new skin cells reach the top layer of the skin. Using a body scrub regularly will help make your skin look more vibrant and youthful.
Benefits of body scrubs through the removal of dead skin cells also extend to moisturising as it allows for the easy absorption of a skin moisturiser into the healthy skin. Ideally, the best body scrub is one that not only acts as a gentle exfoliant but moisturises at the same time. A coffee body scrub like One Scrub does just that.
To achieve a realistic "fake" tan using a self-tanner, you must exfoliate with a gentle body scrub first. If you don't do this to remove any dead skin cells, then you run the risk of ending up with a blotchy look as the self-tanner will darken areas where more dead skin cells accumulate (such as the elbows and knees). If you want a natural looking tan and you use a self-tanner then using a suitable body scrub before applying the tanning product is essential.
