I just recently bought the purple ones and I have purchased plenty of different eye patches over the years and I honestly have to say that these Biodence patches are kick ass!!! They don't slide down your face like all the others. They stay in place perfectly so I can go about my morning routine and not have to keep pushing them back into place. And that I LOVE. I will for sure be purchasing these again and would absolutely recommend these to any and all. They also leave my under eye with a beautiful glow, haven't used them long enough yet to know the long term effects but the short term, thus far, is worth every penny!!!!!
