Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
First time using this product and am happy with the purchase. Can use as a mask if left on for 5 min. Otherwise a nice scrub to use once or twice a week. Not sure what makes it urban, yet to discover this.
