hi it does depend just how bad it is could be from 1 day to 5 days. there are just to many factors to go into but either aloe vera jel and even olive oil will help but just keep it going on it will hurt you till it calms down. but they say getting burnt is a good way of keeping skin cancer at bay but this depends just who you believe. but if its really bad either see your doctor and an er for help. hope this helps you. good luck
