Everytime I go anywhere hot I get prickly heat. Suntan lotion seems to aggrivate it, I've tried the ones that claim to stop prickly heat (they made it happen quicker and be worse than usual) is there any sort of mirical preventative I can take and hopefully not end up like a big red lumpy person when we go away this year.
I've not been abroad since 2005 and really don't want to spent the holiday hitting myself like a mentalist!
