Brave Fairy Brave Fairy brand mask efficacy? Composition? Is it a patented product? Why is it so hot?

Yes, I used the brave elf product of the brave elf. At first, I was attracted by my nickname and only confessed to you. Then my boyfriend gave it to me. Hahaha, when I first opened it, I felt deeply, mainly because it was more convenient to use, clean and moist than other products, and made the products used later better absorbed.
