I recommend the RNW mask pack.

The RNW mask pack I bought because of the good reviews

I actually tried it and it’s really good. The mask pack is black, so it’s a bit unsightly, haha, but oh well, only I’ll see it anyway. The essence volume is huge, and it doesn't feel light; after using it, it feels like my skin is fully replenished deep inside. Both the hydration and oil balance are perfect, making it the best value product among all the masks I’ve tried, haha.
