First, take some aspirin or ibuprofen. Their anti-inflammatory properties will help reduce the pain and swelling. Next, try taking a cool bath with baking soda or oatmeal added in to help soothe your skin. You can also add baking soda or oatmeal to a cold compress and apply it to your skin to help take away some of the redness and pain.
If a bath sounds too painful, try applying some aloe vera to the burned areas. Aloe vera is great natural remedy for taking away the sting and reducing redness caused by sunburns.
Finally, dont forget to drink plenty of water and moisturize your skin regularly until the sunburn is healed. When your skin is burned by the sun it becomes dehydrated, which can cause the healing process to take longer. By drinking water and applying cooling moisturizer, you help to replenish your skin back to its natural state faster.
