I recommend the Mediheal mask pack that I bought with my own money.

I recommend the Mediental by Mediheal Collagen Impact Essential Mask. I happened to buy this product at a supermarket. It was sold as a set with both the mask and a foam cleanser. When I used it for the first time, I liked that it was more moisturizing than regular mask packs, and the sheet was thin, adhering perfectly to the skin without any unevenness. It is even more effective if you use the mask pack after exfoliating.
