Hello. I’ve suffered with this as well. I constantly went to dermatologists just for them to say it’s acne. My case is different. I would have a patch on my face filled with demodex. Being tired of not getting any solution, I had to research myself. Once I realized what it could be, I started to look for treatments. I finally found a solution. METRIN %5 Permethrin Cream 30g/1oz Treatment of Scabies. I would would put a thin layer on my whole face and a slightly thick layer on the specific areas on my face where I had an infestation. I would do this every morning and night after my skin care routine. I knew it worked when my skin would be full of white like mucous material you described. I’m assuming they were the dead ones that were on my face. It takes a few weeks to see your face clear up but it’s worth it. If it wasn’t for this cream, I would be confined into my home from shame.
