Summarize this article in one sentence.
If taking a bath in regular tap water isn’t helping reduce the itchy symptoms of your eczema, try adding Epsom salts to the water. You can also try adding Himalayan salt instead of Epsom. Add a generous amount of salt—about 1⁄2 cup (120 mL). Then, take a 30-minute bath. Then dip down in the bath so that your face is underwater. This will allow salt onto your facial eczema.  Or, if you dislike the feeling of your face being underwater, try splashing a few generous handfuls of salty bath water on your face. If salt doesn’t help, try adding 10 drops of an essential bath oil like lavender or chamomile. Tea tree oil is a great natural way to reduce symptoms of burning or itching sensations. While tea tree oil won’t treat or remove the eczema itself, it can provide temporary relief from discomfort.  You can purchase vials of tea tree oil from most natural foods stores or the organic section in large supermarkets. Tea tree oil is sometimes sold in a spritz bottle, making it easy to apply to a patch of skin. Vitamin E can also provide relief from the uncomfortable symptoms of mild eczema. Visit a natural foods store, and look for vitamin E that contains natural D-alpha tocopherol. Dab a small amount of the oil on your finger, and smear it over the part of your face with eczema. Do not apply synthetic vitamin E oil to your face, as it may contain ingredients which worsen the condition of your eczema.

Summary:
Add salt to your bath water and soak your face. Apply tea tree oil to your eczema. Apply vitamin E oil to the facial eczema.
