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.
$13 for this?! That is an amazing price for what this offers. This product has so much versatility it is truly impressive. I use it as like a face mask at night, for cuts and burns, and as a moisturiser during the day (a few hrs before I wash it off).
