This is the AHC Essential Mask.

AHC's Moisturizing Essential Mask!

It is a dual-functional cosmetic product for whitening and wrinkle improvement.

It is an eco-friendly natural sheet that adheres perfectly to the skin and is mild and soft.

I also like that it doesn't really have a scent.

If you leave it on for about 20 minutes, you'll get the feeling that it's okay to take it off haha

You all know that leaving it on for too long isn't good, right?

I have this in a small box in the refrigerator. Was it a set of 10 or 20...

It says it's good to use 3 to 4 times a week, but being lazy, I guess I only use one or two sheets a month... haha

After using it, my skin feels moisturized, but the essence isn't too runny; it's just right.
