Tomato juice is highly beneficial for treating sunburn blisters. Take one forth cup of tomato juice or tomato paste and mix it with one and a half cup of buttermilk. Apply this mixture on the affected skin area and wash it off with cold water after half an hour. This will alleviate the constant burning sensation and will also ensure faster healing. Another option is to add two cups of tomato juice to your bath water and allow your body to soak in it for ten to fifteen minutes. Alternatively you can mix one mashed tomato with some crushed ice and then gently apply it all over the affected skin area to get immediate relief from the pain.
