This is totally my fault. I forgot to bring Aquaphor in my purse. I was at work all day and could not moisturize my lips. This is the result... and it HURTS! Oh GOd, the other day I did the same thing I I don't learn, I guess. I pull on the skin on my lip, trying to bite off the little bit of skin... DON"T EVER do that! I pull too far and peeled off a chunk of skin. It hurt all day. But I used aquaphor over night and the pain was over by morning.
