Does anyone know about 313nm light to help eczema?

I was reading that a possible way to help reduce eczema is using specifically 313nm light.

Does anyone know any details about this possible phototherapy?

Thanks David

There's a free article here which gives some background to it David - https://www.tandfonline.com/doi/full/10.1080/1744666X.2020.1672537

Thank you Jonathan.

However that article seems to focus on immunosuppression for psoriasis. It did link to this article, which I hadn't read yet

https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.14891

 

Which indicates dosage. The main thoughts I was previously reading was about local vitamin D increase. But then why not just rub in a vitamin D drop? It fat soluble and would easily cross into the skin.

The antibacterial thoughts make some sense on local accessible skin or antiinflamitory thoughts.

 

I don't know the cause and was surprised 313 or 308nm could be a treatment. As I can administer that

But I don't have a dosage meter. But I may not as wouldn't want to cause other skin damage or problems.

 

So still curious about this.

Narrow Band UVB photherapy has been around for some time.

 

Here is a link to a supplier and more info.

David, in the paper I sent the authors say that while psoriasis and AD (atopic dermatitis) are clinically different, they both have activated T-cell infiltration into the skin. The UVB has an immunosuppressive effect for both. Dermatologists use the term 'eczema' and atopic dermatitis interchangeably.

Thanks John and Jonathan.

I don't really trust my Dermatologist, as I think he was limited in thinking what it could be before seeing the subject.

Now that I look closely I am seeing punctuate red in the general cheek rash. So there might be some Staphylococcus aureus infection.

We have decided to try 2.5% hydrocortisone. Which looks to be helpful.

I might just try 313nm light, if that doesn't clear it.
