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.
I thought the tiny needles would be too small to feel, but you can definitely feel them. Not too painful, but a prickly reassurance that it is doing something. You can also see the patch fade as the stuff dissolves, pretty cool. That being said, I don't like the packaging. There is a lot of adhesive space around the part with the needles, so you can't get as close to your eye as you want to, and the microneedle area is really small. Some of my patches were dry upon opening them. As far as effect...this may have helped with some fine eye lines..? Subtly, and not immediately. Like they seemed to become shallower in the weeks after using the patch. It didn't seem to do much for my smile lines. Kind of an expensive product for "maybe helped", but not terrible...I'm going to try some other microneedle patches for comparison.
