I just wanted to remind people about something that happened to us last summer.
Took ds to a local thing and he had his face painted, it was a hot day, lots of running about etc.
The next day he was very red and his skin started to blister, where the paint had been. I was a bit shocked and thought at first it was something like impetigo, but soon realised it was in the right place to be a reaction to the paint.
It was just a casual facepainting stall, not sure what type of paints they were or anything, but if you are going to have it done please be aware that this can happen.
He was Ok in a few days but it was sore and I took him to the GP who prescribed an antihistamine in case it swelled up more.
Maybe he was jst allergic to it - I don't know, but he isn't an allergy prone person generally.
That's all - hope it helps someone.
