I received this as part of Suzykirei's giveaway! Thank you! Until recently, I'd only used face masks when I received them as gifts or souvenirs, but my postpartum skin wasn't feeling so great, so I started buying some myself! I'd been curious about this face mask, so I'm excited to receive it and try it out! I've never used a two-step face mask before, so I'm really looking forward to seeing results! First, the Aqua Serum in step 1 has an astonishingly high viscosity! I once received a snail face mask as a souvenir from Korea, but this one feels even more mucus-like, like it doesn't drip even when you hold it upside down in the palm of your hand! However, when I applied it, I was surprised that it wasn't sticky at all. I'm excited to think that this will enhance the effectiveness of the next sheet mask. Next is the Aqua Mask in step 2. This is the thickest and largest face mask I've ever used, and the holes around the eyes and mouth are larger than others, so it's a bit disappointing that it can't be used to mask the under-eye bags or the areas below them. The mask feels thick and full of liquid, so 20 minutes passed while I was doing other things, but the sheet still remained moisturized (although with some masks, the sheet seems to start drying out within 15 minutes). My skin felt moisturized after the mask, and my pores seemed less noticeable than usual. It also seemed to penetrate my skincare routine more effectively, so it looks like it'll be my go-to product for those times when I'm feeling a bit under the weather!
