While on vacation one summer I got a REALLY bad sunburn, included were those awful blisters. Later I was swimming in the ocean and the blisters disappeared. Carefully wet the blisters with cool water and sprinkle an ample amount of regular table salt to it and let it dry. You may want to rub the salt on the blister a little if you can stand it. Let the dry salt stand on your skin for 30 min. to an hour depending on the size of the blister. This has worked well for me in the past.
My father was a fire fighter and this is his cure. If a sunburn has blistered, take a bath with Tide Laundry detergent. The pain should go away as well as the blisters.
apply vitamin E cream to affected area and take vitamin E supplements. This will not cure the sunburn but it will help reduce itching and will speed healing
This will work for sunburns or any other kind of burn...apply regular yellow mustard to the burn. Once it dries, wash it off and this will prevent it from blistering. It really does work. I have trusted in this remedy since I was a teenager.
Do not use baby oil or any lotions with lanolin when you are in the sun.
Apply some sandalwood paste to affected areas.
Apply aloe vera gel before and after you are in the sun to prevent and minimize sunburn.
For sun tanning, use lotion with PABA to minimize sunburn risk while still tanning the skin.
For facial sunburn, apply whole wheat flour mixed with milk, olive oil, or barley flour, honey, and raw egg white paste.
Apply cold aloe vera gel, apple cider vinegar, or plantain to help heal sunburn.
