What is this??

My daughter had just a little bit of red around her mouth when I picked her up after work at 6pm, we went to eat at a Japanese restaurant and she had rice with a little bit of yum yum sauce, and now it’s even worse and very red. I don’t know if it’s chapped from her pacifier, or maybe a food allergy? My father in law watches her during the day, and he said he didn’t feed her anything abnormal today. Just wondering if this has happened to anyone else’s baby??
