Instant Glass Skin!
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried SO many sheet masks and this collagen one is genuinely one of the best. My skin looked insanely hydrated, smooth, and glowy after just one use. It fit my face really well, stayed soaked the entire time, and didn’t leave that sticky feeling afterward. The next morning my skin still felt soft and looked brighter. Perfect before events or whenever your skin needs a reset. Definitely repurchasing!!

Absolutely amazing masks!!!
Scent: Collagen, Size: 4 Count (Pack of 1)
These masks are beyond amazing! I use one once a week and leave it on overnight after completing my p.m. skincare routine and wake up to smooth, plump, moisturized, and absolutely glowing!! I have extremely sensitive skin and eyes and these masks do not bother me at all. No burning in my eyes and no irritation of the skin. My deep wrinkles seem a lot less pronounced and some of my more fine lines almost disappear for 24 hours after using this mask. They are simple to use and adhere to the skin perfectly even after applying serums and moisturizers. Once the mask is completely absorbed and becomes clear it peels of the skin with ease. Based on the quality of these masks I am shocked by the low price, it is such a great value for your money. This Mask has become a staple in my skincare routine and I will continue to purchase these!!

instantly more hydrated + glowy skin
Scent: Collagen, Size: 4 Count (Pack of 1), Scent: Collagen, Size: 4 Count (Pack of 1)
I love this mask. It’s one of those products you can actually see a difference with right after using it. It really helps with: 1. Deep hydration – my skin feels plump and moisturized, not dry or tight 2. Smoother texture – it softens everything and makes my skin feel really smooth 3. Glow/brightness – gives that fresh, healthy glow without looking greasy How I use it: I apply it on clean skin (usually at night), leave it on as directed, and let it fully absorb before removing. I like using it when my skin feels dull or dry and want a quick reset. Overall, it’s super easy to use and makes my skin look more refreshed every time. Definitely a go-to for me.

Woke Up Glowing ✨ (But Sleeping In It Is a Stretch lol)
Scent: Collagen, Size: 4 Count (Pack of 1)
I was honestly impressed with this mask! It feels super soft, cooling, and refreshing while wearing it. The jelly texture makes it feel really hydrating and luxe, like a mini spa night at home. My skin looked smooth, plump, and GLOWING the entire next day after I took it off. Like… noticeably radiant. I also have sensitive skin, so I was a little nervous trying it at first, but I didn’t have any irritation or reaction at all. My skin felt calm, hydrated, and refreshed afterward. One thing I actually liked was that the mask was easy to customize a little. I have a nose piercing, so I just tore a small piece near my nose so it would fit comfortably without irritating it. The material held up perfectly, so that was a nice bonus for anyone with piercings or who just needs a better fit in certain areas. My only complaint is the “sleep in it” part of the instructions. I personally don’t see how that’s possible 😅 The mask stays pretty moist and jelly-like the whole time, so it felt uncomfortable to lay down in and I kept feeling like it would slide around. I ended up just wearing it for a while before bed instead. Overall though, the results were worth it and I’d definitely use it again for the glow alone!

Nice mask! Caviar
Scent: PDRN, Size: 4 Count (Pack of 1), Scent: PDRN, Size: 4 Count (Pack of 1)
The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.
