Fantastic mask, I have used plenty of different masks through the years and Pyunkang Yul so far wins! With other products I always felt a bit of stinging because of my sensitive/irritated skin. This mask is very delicate, I didn't feel any irritation and actually felt like my skin did calm a little. Very gentle and m good product! definitely recommend! I also recommend their moisturising mask, I'll just say - I haven't felt so moisturised in a long time... give it a try!
