It's incredibly moisturizing! After using it, my face's tone improved noticeably and it became softer and more supple. It was the most effective skin-improving pack I've ever used in this price range. It also makes a great gift.
I'd heard on YouTube and social media that this mask whitens your skin, so I bought one from the Suzykirei store and tried it out. I felt a slight stinging sensation while wearing it, but when I removed it after 10 minutes, I didn't notice any difference from other masks. The next day, my face felt firmer and slightly more toned than usual. My skin also felt drier than usual. It's a bit pricey, so I think it's fine for occasional use.
The yellow sheet is thick and adheres well to the face, fitting perfectly! It contains plenty of serum and has excellent moisturizing properties. When I apply it at night, my skin stays hydrated until the next morning, and I feel like my skin tone is one tone brighter! I recommend it to anyone who is concerned about dullness.

This is a must-have pack for your home! I love packs so I've tried a lot of different ones, but this one is the one that improves the condition of my skin the most and makes it more translucent, so I recommend it! The sheet is thin and adheres firmly, so it doesn't slip off! I highly recommend it!
