I too get something similar. But only in the south...never here in VT...weird huh!
But anyway- this is what I did last time, and before anyone starts yellin about skin cancer...spend a vacation with the nasty itchy rash and see what you do!...
I tanned before going....having a small base, kept it under control. I also take Benadryl DAILY when I'm on vacation...I also pack Avena's oatmeal bath LOL...dont laugh I've already got it packed for next week!
I pack benadryl pills, the liquid clear anti itch gel, and oatmeal bath.
I also use 45spf..and it still didn't help.
The only thing that I did different last time was 8 visits to the tanning booth- 10 minutes each...I finish up mine next Wednesday for this trip...
