Allergy to UVb (the sun!) He has to wear (his) sunscreen year round and even inside. This will only have an impact for camps etc as he will be wearing it during normal meetings. He is also allergic to a number of skin applied chemicals (including most UK sunscreens so he must use his own). Generally, these won't be an issue on a weekly basis but he can't have face paints or anything else applied to his skin as it is likely he is allergic to them. He knows this. If he goes on camps etc then we will give some antihistamine and also steroids just in case.
