To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Been using this at least once per week for a month now. Good exfoliator. Effective in getting rid of dead skin. Noticed difference/reduction of bumps around my knee. Value for money. 10/10 would recommend.
