I liked this sheet mask, so I decided to buy this one too. I have sensitive skin, and even with popular or highly rated skincare products, it's hard to find one that suits my skin type, regardless of price. This one worked without any issues. I tried it after washing my face in the bath, and was surprised by how much better it worked than I expected. It didn't seem to have any particular effect on my pores, but I was surprised by how my dull skin became incredibly white after just one use. Pores were my biggest weakness, and I was also quite troubled by dullness, so the results were very good. It's not amazing, but even products for sensitive skin sometimes don't work for me and cause stinging, so I don't have many options, so if I continue using this one and don't have any problems, I think I'll repurchase it.
