A few years ago I went on a vacation in the British Virgin islands and developed tiny bumps on my skin after prolonged sun exposure everyday of the trip. This week I took a similar vacation to the Bahamas and again after sun exposure they have reappeared. I believe it's a sun allergy. It went away after some time last time. Ive been reading up on treatments to get them to go away but how can I prevent them. I am a sun lover and want more sun.
