I think all of Innisfree's face masks are good.

I often buy various face masks from Innisfree because they offer great value for money. They are all pretty decent, though. But this time, I tried the Retinol Green Tea PDRN Gel Mask, and it was seriously amazing! Right after using it, I could immediately feel my skin becoming firmer and my texture improving. It is a bit more expensive than other Innisfree masks, but I really, really recommend it.
