Use Tide powder. Enough to make the water feel slippery.A small mixing bowl size for the water. Mix it until the tide has dissolved. Then use a washcloth and don't ring it completely out and gently pat the the sunburn. Make sure your skin it really wet. Leave it on till till it sort of soaks in a little and then just lightly pat the sunburn with a very soft fluffy towel. Don't pull the skin. Just pat or blot. I swear this will work and it also takes the pain away. I oncd burned the palms of my hands trying to put a brush fire out. I tried to scoop up sand not knowing it was hot. Talk about pain. Try to sleep with your hands in a bowl of tide water. It is amazing. A very old little southern lady told me about this. It really works. Try and let me know what you think.
