I can't read Korean, so I'm not sure if you are supposed to use this on your face or not... I used it on my face a couple of times and it was terrible. It make a white, ghost-like sheen on your face (I looked haunted) and it flakes badly. Don't try and use this underneath a foundation. The foundation doesn't stick to it.
I've tried using it on my arms instead... I guess it blocks out the sun as it's supposed to, but my arms had this weird pale pink film over it. I'm sorry, by I'm not a fan.
