If you have some potatoes and a blender at home you can make a natural sunburn treatment.
Take a potato and slice it up or grate it and place it in a blender and blend the potatoes until they become liquid and you may have to add some water to make the potatoes more liquid.
After you turn the potatoes into a liquid you can take some cotton balls and soak them in the potatoes liquid then just apply the potato paste onto your sunburns.
You can also just lay slices of potatoes on your sunburns as well which will help sooth and treat the sunburn.
You can also soak a washcloth or compress in some cold milk and apply the compress or washcloth to your sunburn.
Cold milk is a good natural way of getting rid of sunburn.
