Thanks for your inputs. Ultimate challenge, no asbestos, but probably some mold as the place was exposed to a broken window and roof a few years. Swallows lived in there, cleaning that out too, I am probably vaccinated against bird flu forever :)).
Concrete walls, 2-3 old layers of paint stripped off. House not used the last 3-4 decades. My soon to be office!

Then you have the modern toxins from chipboard (new floor)
spray paint and water soluble paint. Not the worst paint though, diffusion open paint, not latex.

So far only symptoms on face; a yoghurt mask helped the burning, thanks V.
Then some Colloidal Silver to keep it moist. Some gold too.
The challenge is to not supress the reaction, more help the body to handle it.
I will go back to my old homeopathy books, find the antidote for all these old toxins. Lead in particular.

Clay; I cant take it internally as it is too drying for me, but I have a good rhasshoul clay soap that is about the only thing I use on my face.
