Have you all tried the Livihill mask pack, which is said to be the ultimate moisturizing mask this winter?

How are you all managing the extreme dryness and hangnails this winter? Right now, I'm constantly bothered by the hangnails at the end of my nails, and I almost bled while picking them off... Even with the humidifier on full blast, I feel like my skin is going to tear, maybe because of the heater. At 10:58 PM, I was wondering what was going on, so I quickly opened a Libby Hill sheet mask and stuck it on my face. This Libby Hill sheet mask has a massive amount of essence, so I applied the remaining essence all the way to my fingertips and elbows. Amazingly, my hangnails have calmed down! I wonder what I would have done this winter without Libby Hill sheet masks. Are you all using something like Libby Hill sheet masks, which are just the right thickness and keep dryness at bay until the next day? Or are there any of you who, like me, use the leftover liquid from the sheet mask to moisturize your entire body? It's the end of the year, so I have a lot of gatherings, but my face is puffy and I'm really worried! If you have any winter moisturizing secrets, please share them in the comments! What are you doing instead of sleeping?
