Hello, my 8 year old daughter sometimes has a discolouration above her lip which looks like she had a moustache. It is reddish in colour, but it is not always there. She got it today after she was crying for a while, but I am not sure this is cause as at other times it just appears. It is almost like the skin is sore from over wiping a runny nose, but it is not raw. She is blond and fair skinned, so it looked very odd and prominent. Any thoughts?
