I never write reviews but these surprised me!A couple years ago when I got my lashes done, the lady put eye masks under my eyes and I loved the moisturizing effect. When I looked into buying them myself, I couldn't really justify the price.At places like ulta you'll pay a pretty penny for only a few. The effects are temporary so if I want to use them every day, I can't really justify paying $5 a day for eye stuff.But these are such a great value!!! You could literally use them every day and only be spending about $8 a month.I didn't expect them to do much because most eye products really don't do anything, even the expensive ones. But I saw and felt a difference after just one use. Dark circles aren't as noticeable, puffiness has gone down quite a bit (not completely), some wrinkles looked smoothed out. Yes, it's just temporarily I know. But as part of a good skin care routine, it just helps you look a little better. I wish I had time to use them in the morning when my eyes look the worst, but I am always rushing to get ready for work. I used them while I watched netflix and relaxed. Wondering now if they have this in a full face mask. After you remove them, put moisturizer on top to keep the serum locked in longer. I didn't have issues with them sliding down, but I had a clean face and was leaning back watching tv. I'm sure if you tried running around with them on, they would slide down your face.
