Not sure 2 months ago I received 2 patches of the eye mask last week. I use twice time this week. I feel cooling and soothing during the 15 minute when I use them, but after I removed them I feel a little tingling under-eye area.
Doesn't Work For Me. 2 months ago I received this as a sample and decided to use it on my under eye puffiness. And after 2 usage, did not see any improvement in the puffiness.
