Help I need sunburn tips (to help a sunburn heal not prevent it because obviously wear sunblock)

I got a pretty sweet burn yesterday and personally I don't burn much so this is kinda strange. I did wear sunblock but forgot to reapply after a few hours. My shoulders are looking like a tomato and feeling very painful. Any tips to help with the calm the redness and to sooth that sweet burning sensation? Aloe seems to help for a short time but I'm looking for different solutions. Thanks!
