These are a winner!
Color: Caviar PDRN
These are some of the best under eye masks! I have friend about 35 different ones and these are slightly textured so they do not slip as much as a lot of the other ones! They are thin and very hydrating!!

Favorite mask brand’s great eye patch
Color: Caviar PDRN
Love this - i always loved biodance masks. It cools down my undereye & definitely helps with eye bag. It stays on skin perfectly. I usually put this on after shower before bed and walk around do my things then remove right before sleeping - it usually thins out a little by then. Very moisturizing for my under eyes

FYI These are worth it!
Color: Caviar PDRN, Color: Caviar PDRN
These eye patches are really nice and worth it. I use them mainly on the weekends (when I don’t wear makeup). I wash my face and apply them under my eyes (I have also used them on my neck , forehead, corners of mouth, and between the brows for extra moisture) I leave them on about 30 minutes or more, peel them off, pat in the left over product; and my under-eye area looks a lot brighter and awake! I then apply and complete the rest of my skincare routine. (Under eye serum, face serum, and moisturizer). These patches are also very pretty, they make me feel like a mystical sea creature; think mermaid! My advice is make sure you are in fact using one, they are very thin and transparent and a few times i was actually applying more than one. With that being said there are A LOT of patches in the container.

Color: Caviar PDRN
I love these. I put these on every morning when I’m getting ready. Sometimes I’ll even leave them on under sunglasses if I’m just doing school drop off 😆 They don’t slide off, they really help brighten and de-puff my under eyes, they have a cooling effect, unscented, and there’s no irritation. They also help concealer go on super smooth. I recommend!
