It stings for few seconds when you apply it at the first time. After 1 week use, I dont see any significant result on my under-eye area, it only feel softer right after application, but the effect didn't last long. 

It's an okay product, gets the job done. My eyes feel refreshed after using them.

these are the first eye patches i have used, an i really enjoyed them! my eye area felt really refreshed and using any kind of mask product is always fun. my eye area has definitely improved.

Feel nice and very relax when use it
