Eczema, Acidic Skin & Sunlight

Have you ever heard that sun exposure can help to treat eczema? A new study has found that yes, there is a co-relation.

There is a relationship between eczema, sunlight, and the natural acid in the skin.

Acid occurs naturally in our bodies, and a study has found that the acid helps to regulate the immune system. A lack of this natural acid in the skin could be triggering eczema according to a recent study at Edinburgh University. Using skin and blood samples, researches found that less naturally occurring cis-urocanic acid cells are likely to negatively impact the immune system and the skin, leading to inflammation.

Where does this acid come from? Some people find that their eczema improves when they expose their skin to sunlight. This makes sense, as most people’s skin produces this acid naturally in response to sun exposure.

How does this relate to you and your eczema or your child's eczema? Try getting 20 minutes of sun a few days a week.  After getting a small amount of sun watch and see if it improves your eczema or your child's eczema. The sun produces Vitamin D in your body. Consider taking Vitamin D.  Studies show Vitamin D can improve adult and child eczema. Talk to your pharmacist about proper dosing of Vitamin D, especially for your child's eczema.
