I purchased these eye masks to help with dark circles and puffiness. I've only used them a couple times, that's why the 4 stars. I'll give an update as to the results, when I've had a chance to use them more. What I am basing the rating on, is the quality & ease of use of the product. It comes with a plastic spoon to help remove the pads from the jar. The pads are easy to apply, they stay in place once you put them on. There is a bit of excess lotion which you can massage in after waiting the 30 minutes that they recommend you leave them on for. I did have to adjust them. I didn't have any problem doing this. It is too early to say how well they work, but I will post an update. It felt really nice on liekit was doing somethign but again I will keep you posted!
