Im in love with these under eye patches. These are not your regular under eye patches. My eyes look refreshed and hydrated. I often keep them on all day and i love the tightening effect after they dry down. My under eye feels firmer and looks plumper. Sometimes i will even wear them overnight. They are very cooling. I love that they are clear so not very visible on zoom meetings. For all that it does, it is definitely worth the hype and the price.

Provides cooling to tired eyes

These patches feel really good under your eyes. They are cooling, reduces puffiness, reduces discoloring and bags under the eyes. The only issue I have is not staying under the eye very well. Other than that they moisturize quite well and they are effective. The scent is very subtle so not to irritate your eyes. I use this line of products so I would definitely recommend

Great for crows feet

I thought this was a cream it is actually patches. They adhere well and are great while sleeping. I noticed a reduction and wrinkles around my eyes after the first night. There was a generous supply of product on the patches and are worth the money.
