oh boy i know what to do! finally growing up as a pasty ass hoe in hawaii pays off, ive gotten AWFUL sunburns
basically you need to lay completely naked (i kno, i kno) on your bed/something soft like a towel and then have someone just. SLATHER you in aloe
and i mean like, fresh aloe if you can get your hands on it seems to work soooo much better
and basically just lay as still as possible
and when your skin is peeling itchy DO NOT scratch it and let it come off naturally and youll have a much better time and also prevent scarring (depedning on how bad the burn is, if youre getting a scar its probably bad enough to consult a doctor haha)
and also, sitting in the shower with cold water running over your shoulders/back tends to make it feel a lot better as well as putting ice/cold compresses on the worst areas

hope you feel better!

THAT'S ACTUALLY REALLY GOOD ADVICE Cause I am.. white as hell... I just used some Emu Oil?? it's some stuff I've used for burns since I was super little and does really well. MY bf got crazy bad sunburnt as well so honestly we could probably help each other haha

Australian confirming that emu oil is pretty alright; you're basically just keeping the skin soft and taking care of it to prevent it from being infected; the longer the burnt skin stays intact, the better.

Sunscreen is a good investment tho :3

THE CRAZY THING IS THAT I LIKE

DROWNED MYSELF IN SUNSCREEN

I don't know why it didn't work!! The sun was REALLY strong and we were on the river, so maybe it just wasn't good enough..

Check the SPF (sun protection factor) of your sunscreen, the age of it (10+ years doesn't work) and howw long you used it for. Generally you replace sunscreen every 3 hours down under, and it -will- wash away in water unless your sunscreen is water resistant; in that case, you still reapply sunscreen every hour if you're in the surf.

Get well soon :p
