Can the scrub stone be used for other purposes, and not just as an exfoliator ?
Yes, it can!
It actually has a natural healing effect, so you can use it on spots (acne or blackheads), itchy areas and mosquito bites. It also helps to get rid of bad smells (sweat, garlic on your hands after cooking, etc.). And last but not least, it can smooth calluses and rough, dry skin on the heels, elbows, knees, hands, etc.
