Such a pampering treat!
Color: Pink (PDRN)
Ok I love these!!! I’ve started using them almost every morning! They just feel like a little pamper before I start my day. They definitely tighten up my under eye and decrease puffiness. I try to leave them on for 25 min or so. Maybe not quite as good as the Peter Roth but I feel like I can use them frequently due to the reasonable price point and still see some results. I save the Peter Roth for a couple times a month. Definitely repurchasing these.

Hydrates well
Color: Pink (PDRN)
So far the product has been nice. My understanding is that eye area looks hydrated. It does not diminish the under eye bags. Have been using for a few weeks. Maybe I’ll give it more time to see better results.

Super hydrating!!
Color: Pink (PDRN)
I love theses eye patches so much! Not only are they very hydrating for the under eye but the price point is *chefs kiss*! They stay in place and do not slide all over your face. Super easy to use. 10/10

Eye patches that work
Color: Pink (PDRN)
Love them! Cooling to the eyes, easy to apply with no slipping. These eyes patches work and they’re great for the price. The only patches I’ll buy going forward. I just apply my eye cream first and then follow with the patches and you can definitely see the results once removing.
