I bought a 10 pack of these because they were so hyped and I thought they'd work wonders for my skin. The mask sheet is a lot thicker than other masks I've used so it stuck quite sturdily to my face. The most unique feature of these is the little flaps for covering the eyelids... I feel a little vulnerable covering my eyes when I'm wearing a sheet mask so I folded these down! They don't really smell of anything either, so there's probably little to no risk with fragrances. The essence is just enough to soak the sheet; the sheet isn't dripping with essence like some other brands, so if you're like me and you like using remaining essence for the neck, hands, arms, wherever, you'll be limited with this one. I left the mask over the recommended time as always, and when I removed it I was a little underwhelmed. For the hype it was getting I was expecting a huge difference but I didn't have that. It's nicely moisturising, and it's calming just like any other product with a lot of snail secretion filtrate in it would be, so for the price I'm not very convinced. Maybe it'll have a long term effect that'll only show up once I finish the entire box. For now, I'm still sticking with cheaper sheet masks though.
