Sunburns can be horrible. Take two ibuprofen as soon as possible, to help with the swelling. You make also use plain aspirin, it works just as well.
Step2
There are many homemade compresses, that you may make, to help relieve the burn. Witch hazel works well, just soak a rag in witch hazel, and apply to the burn. Skim milk is also good for a compress. Use one cup of skim milk to 3 cups of water, and toss in a few ice cubes. Again, soak a rag in the mix and apply to the skin. You may also want to sit in front of a fan, while you apply the compresses, for a little extra relief.
Step3
If you have a sunburn all over, you might want to soak in a bath instead. Use cool water, and add 2 cups of vinegar, or baking soda, this will also help to cool the burn. When done pat skin dry with a soft towel, and apply plenty of moisturizer. If the burn is bad, you may want to apply a local anesthetic, like solarcaine, for added relief.
