Hiya, I always use Avon skin-so-soft spray oil and it works great. Put it on in the morning and after your shower at night even before going your holidays it really works.
Years ago my mother suffered with this and while on holiday in S Africa a pharmacist gave her a recipe : Johnsons baby power
Fuller's earth and borassic acid powder but I am not sure as to the quantities but it did work.
Having suffered with this for mover thirty years I can offer you two pieces of advice which I find work for me:
the first - take a antihistamine tablet, and the best and second piece of advice - KEEP OUT OF THE SUN.
Probably not what you wanted to hear, but it will help your problem from getting worse.
I have also suffered with this for years and then upped my sunscreen to factor 50. I have never had it since. You do still get tanned but without the prickly heat.
