Use withchazel or rubbing alcohol in a spray bottle or modern burn treatments the first day. Evaporation of the witchhazel or alcohol will help cool the area. BTDT before I figured out that my sunscreen needs to be either shade or spf 30+. Don't forget about reflected sunlight either. Worst burn I ever got was at Panama City. Water, white sand, white concrete & not a cloud in the sky. Already knew I burned easily & went indoors when I had barely started turning pink. Second degree burns & sun poisoning from bottom of shorts down.
