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 hadn't used a lash serum before so I kind of just figured that's how they were but still wanted to give one more a try. I researched some options on Amazon and settled on this one. Good reviews, reasonable priced, why not...I've been using it for 2 months now and OMG...its legit. I look like I wear fake eyelashes and I LOVE it! I have used it religiously every night before I go to bed and I could probably go down to one time every other night...but I'm kind of enjoying having ridiculously long lashes. I have no idea whats in this stuff but its got me hooked.
