I’ve tried many eye masks over the years, some I go back to some I don’t. I was very impressed with these, I purchased by reviews, not so much interested in young 20+ reviews as they can’t really give a definitive review of the product. They didn’t slip down my face & were so easy to use. I noticed a difference immediately they really lightened up the skin under the eyes. It lasted quite a few hours, mire than most that I’ve tried. The price is very affordable also.
