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.
I had horrible ingrown hairs, razor bumps and suffered from really itchy legs after shaving with a generic shave gel. So did a bit of research and read some reviews then decided to try this one even though it's 10 times more expensive it's so moisturising and my legs no longer have red bumps or itch. Glad I purchased I just wish it was more affordable
