First you need to apply something like aloe lotion or sunburn cream then wear something really loose so you don't rub the skin.

I am a natural red head I fight sun burn all the time these are the best things I have found Urea cream can get at a pharmacy will make your sunburn almost completely subside overnight, slightly hard to find and kind of expensive Cold cream - you may have to ask your mom/grandmother (older adult woman) about this but you can get it at the pharmacy or grocery store it was used as a makeup remover but its super moisturizing, and its super cheep Baby oil helps a ton use as your last resort though tends to stain sheets and clothes, if I go this rout I sleep on a towel in underwear The key is to get moisture to it as best as you can, avoid anything with Fragrance in it as it will irritate the burn
