I'd like a face mask recommendation.

I recommend the CNP Intensive Soothing Ampoule Mask Pack.

I don't think there is a better mask than this for replenishing skin moisture.

One pack is divided into Step 1 and Step 2. First, soothe your skin with the Step 1 soothing ampoule, and then apply the Step 2 mask to deliver rich hydration, leaving your skin moist and soft. It contains hyaluronic acid, so it is overflowing with moisture.
