Sorry if this is a silly question, but I've discovered my face is now unable to take chemical sunscreens. I've tried Neutrogena and Peter Thomas Roth as well as Aveeno, and they all now irritate my rosacea and cause severe flushing and burning.
My question is - is it OK to use them on my neck and backs of hands? Or is my body now allergic to them? I don't know if there's any way to tell, but so far I've been using them without any side-effects on those areas. But could they still be penetrating the skin and storing up trouble?
Again, apologies if this sounds daft, but I'd hate to chuck out my unused tubss, yet would hate even more to provoke an allergic reaction.
