I received a sample of this in my Birchbox subscription and was very excited to try it. However, when I first applied it I had some chapstick on my lips so they were moisturized. The color balled up and literally wiped right off. I then tried it with completely clean lips and the color sloshed around until it settled in the inner portions of my lips. It would not stain anywhere else. So I left it on anyway to test how long it would actually stay (even if it was only my inner lip,) and it started off with a tingling feeling. The longer I left it, it hurt my lips more and more. They literally felt like they were burning. So for about five hours after completely removing it, my lips were in extreme pain. I've never experience this burning sensation with any other lip product before so I can't say I'd recommend this! Maybe as a cheek stain it would be better, but there are so many other stains out there that are actually worth it. (As you can see in the picture it was a bright pink color, not red like it looks. Also you can see where it weirdly gravitated towards just my inner lips and a bit on the outer corners.)
