Does this sting your skin? What do you think?

I've never had a problem with this mask--we have the same skin type. Maybe your skin barrier got compromised? I know that CosRX products are usually formulated without a lot of excess ingredients and few (if any) irritants.

Ive never had this problem and I use it pretty often. you could be allergic to it :/ ?

Never used it before but perhaps something inside isn’t suitable for your skin? Try it again after a days to see if you still get the same reaction. If you do then most probably it’s not right for you. I’ve used a very well loved product before and it caused my skin to itch. Even on my neck.

I love cosrx product and never had any issues. I'll try it again in a couple if days and see what happens.

Hmmm I have never had that feeling with this. Maybe you had an open wound or a newly popped pimple?
