I recommend the RNW mask pack.

This is a product I have been using consistently for several years. While many brands release white masks, this one is black, and I like that you can visually confirm the generous amount of ampoule it contains. After using the mask, my skin definitely feels deeply moisturized, and it feels like the oil-water balance is well-maintained. I highly recommend the R&W Premium Charcoal Mineral Mask.
