Is it a dermatological condition?

Does anyone think that their fbo could be caused by a dermatological condition? I only ever considered it being a digestive issue because my hygiene is good and my body odor use to respond to normal washing. But it hasn't responded to diet changes or my ibs medication. I'm eating only oatmeal and almond yogurt, still no change. My stool tests are normal. I feel like it must be something else but I don't know any skin condition that could cause this. I'm going in person to work for the first time in a while because I'm hybrid now. I'm wrecked with anxiety, I'm so exhausted I'm considering a bleach bath. I probably won't but also like what could it hurt. My microbiome can't be get any worse.

Anyways anyone considering it being a skin condition? if so what could it be?
