I love these patches! Although I didn't see an immediate effect for the first time, now, after about 1 week of everyday use, my skin has become visibly more hydrated and firm. I keep the patches in the fridge to get a nice cooling effect in the mornings, and then keep them on for about 30 minutes. They don't slide off, so you can just keep on doing your usual stuff. A great addition to your undereye skin care routine!
