To calculate the overall star rating and percentage breakdown by star, we don’t 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.
This product does work very well when used consistently, I found 2 times a week is best for myself. It does not feel comfortable when rolling on the face, however the serum helps a lot to relax the skin after applying the roller.
