Doesn't do anything

It was the slimiest thing I've ever touched but also quite satisfying. As for the effectiveness of the product, I saw no difference in my under eyes other than it being slightly more moisturized than usual. This moisture only lasted an hour at most, maybe even less. It wasn't great, but it wasn't bad either. However, at $10 for a one time use, I expected more. The only really "good" thing I got out of this was being able to say "Hey I have a gold eye mask on!".
