I always keep Cetaphil face wash in the fridge. ANY time someone gets a burn, they get a tepid shower, then slathered up with the cold Cetaphil "soap" leave it on like a lotion then put baby powder over it if its going to be covered by clothing. Wake up the next morning with a NICE tan, no more burn no more pain.
I SWEAR by this stuff, and so does anyone that lives around me that complains of a sunburn. lol
