Mine isn't fungal, I think. I did have a period with a soapy taste on my lips and sebum that stinged the eyes, which made me belief that maybe a fungi was involved, but I don't have this any more, somehow, unless I use topical treatments. I used itraconazole for 3 months, so if there was a fungi infection, it should be gone, but the yellow crusts aren't.
It also doesn't seem to be bacterial, due to the oral and topical antibiotic treatments (unless it's resistant/mrsa) and the negative carrier/colonization swab tests. Also, based on the location (face only), also makes a staph infection less likely.
Demodex could explain it all, but I don't think I have much mites (even before Soolantra), unless they were all inside the pores, hidden from my microscope. But if mites could cause problems, then they could explain everything.
Not sure if Accutane could help, maybe via drying skin that could cause the mites to die out (if that is the cause), but when my skin is dry, it often gets worse (but could be temporary).
I still have my hopes on Soolantra. If it doesn't work, then maybe I'll add oral metrodinazole or oral ivermectin, like the other two did. If that doesn't work, then I want an expert to perform a full skin biopsy.
