It honestly depends. My neck will get sunburnt pretty badly, but my arms, not so much.
I've only gotten sunburns a few times, and both times it's always aloe and long showers with cold, cold water. Ice packs on my forhead as well, otherwise I probably couldn't sleep.
I don't tend to burn but when I have it's been my nose and face. I normally use Aloe gel and I have this oatmeal powder that helps soothe and prevents peeling. I think the powder is by Neutrogena- you basically make a compress out of it and apply it when needed then wash off thoroughly or if you're burnt on your arms/legs then you can pour it into bath water. Makes a big mess though due to whole pieces of oats.
Sunburns are awful! I haven't gotten one in a while though. I generally try to avoid long exposure to sunlight, since I don't like the heat much either. I wear baseball caps a lot too.
