Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
Big words mentioned about this product on Amazon website but the product is a failure. Other less expensive creams/lotions/balms are better than this cream. Not worth the money spent. Odour is not great but one can manage with it if the product works as it is described and expected to be working.
