Chemical pollutants can change your skin bacteria and increase your eczema risk

Silent Spring incarnation.

Greatest existing and future threat to health - rampant chemical tainting of our world.

The main cause of eczema is internal toxicity. One of the functions of the skin is to excrete waste. When the body can't easily remove non-self toxins like heavy metals or chemicals through the usual organs of elimination (liver, bowel, lungs etc) then waste products like dead tissue/cells build up. The body is always trying to maintain homeostasis and protect its main organs, so these waste products are pushed away and expressed through the skin. Clean up the internal terrain and the symptoms ease or even disappear.

The main cause of eczema is internal toxicity

No, it is not, there is no need nor value in a claim that tries to explain something already well understood and does it using impossible mechanisms and contradicting most of the evidence available. The same as the failed theory of aluminum related to Alzheimer's this is only a terribly bad idea that do not correspond at all by what we actually know about the disease. That is why no serious medical professional supports it.

Eczema is such an awful painful disease. I have known people with young children with severe eczema who had to redesign their homes into a dust-free one. Restrict visitors.

Yes it is according to the medical consensus.

Yes it is according to the medical consensus.

Yet you (as usual) are unable to prove this with any reference. There is no evidence that says the cause of eczema is "internal toxicity" that is a false belief, pretending is the medical consensus is just an attempt to mislead people and something usually done by people that tries to profit from those being mislead.
