This is the Jm Solution mask pack.

I have used this company's ampoule before.
It was better than I expected, so I bought a face mask as well.
First of all, I like that it isn't too spicy.
I like that it doesn't cause breakouts, and the moisture seems to last for about two days.
But since the price is 1,000 won per sheet, I think it would be difficult to buy them continuously.

Because there are many mask packs on the market that are cheaper than this price but provide longer-lasting hydration.
I bought it because I was in a hurry, and I used it well.
