I have had perioral dermatitis since March 2013. I know that the root cause of it stemming from my digestive system. I've become allergic to almost all food. Leaky gut symptoms and so on. The POD comes and goes depending on how well I'm doing to with my digestion.
I have just started applying Hydrogen Peroxide to the bumps and I can say that within minutes, there is a difference. The bumps get smaller and less inflamed and the skin around them goes back to normal instead of being red. I use 3% from the supermarket. Is it a cure? I don't know. I have only had one application as described above. A cotton swab held on bump for a few minutes.
I am taking ACV internally and not externally because it just irritates my skin and smells bad.
I will be putting raw milk kefir onto the area later on in the day as a mask. Hopefully, I can report in a few days with some positive news.
