Hi I too get terrible prickly heat I don't sweat all that much but get it overt arms Back legs top of feet and hands it's the most annoying and unsightly thing when your trying to enjoy the nice weather. I was watching QVC the other week on a guatimo show prob not spelt that properly by you'll know what I keen and anyway they have developed a tan excel rotator which is ment to help you put it on every day for2/3 weeks before your holiday and everyday your away and it's mention to stop it. I haven't tried it yet as not been abroad this year and it's not been overly bad here it's 40 pound a bottle bit pricy but if it works it would be worth it. Let me know if anyone has tried it out.
