I recommend Mediheal mask packs.

I recommend the Mediheal NMF Aquaring Ampoule Mask EX. The sheet is made of a soft material that adheres well, so it sticks perfectly to the skin. You can tell it's a high-end mask just by looking at the sheet itself. When my skin feels tight, using this pack makes me feel the moisture immediately. It contains a generous amount of thick ampoule, so I found it to be the best for instantly replenishing moisture.
