The best way to soothe a sunburn, is to use aloe vera. Put it on your sunburn and see the results in a few days. Stay out of the sun and don't take hot showers. Take a cool shower and use ibuprofen for any swelling.
Aloe Vera plant. I am serious, my grandma always made sure she had an aloe vera plant. You just cut off one of the leaves, take a knife and peel the skin off. The inside is kind of slimy, rub it where ever you are sunburned, I used that and only that for every sunburn I ever had, and I have fair skin so I sunburned a lot!!!!
