Mine did, 30 years ago. Totally different "rosacea," though, in my opinion (the only one that counts if I'm the one suffering). Was diagnosed with "rosacea" in my early 30's that i had never dealt with previously. Splotchy face and forehead particularly when hot, sweaty and/or working, or having a drink, beer, etc.

Went to my doctor...he sent me to dermatologist where I was prescribed an expensive metronidizole cream and was told I'd need it the rest of my life. It didn't help at all. Didn't go back to the dermatologist.

Researched online about rosacea and found a doctor in Australia who'd been doing studies on rosacea and he had theories on there maybe being a connection between h. pylori bacteria and rosacea. He had been testing certain combinations of antibiotics to be taken along with strong antacid.

I convinced my DO, after presenting him with much info I had printed out from the Australian site, to prescribe me the two antibiotics and the prescription antacid that were recommended by the Australian doctor/researcher. After completing that course, I had no improvement.

The Australian doctor/researcher had alternative combinations of antibiotics to try so I told my DO that I wanted to try again. He refused, saying, "what you don't know can be dangerous." I suggested back to him that what he doesn't know can be dangerous as well and I insisted that I wanted him to prescribe me the alternative combination. He again refused and I left never to return to that DO.

I found a new primary doctor and explained everything to him about what had been done and what I wanted to do. He agreed. I went through the alternative antibiotics course and I have not had "rosacea" again since...about 30 ago years, now.

I've been putting "rosacea" in quotes because I believe it can be one thing for one person but something totally different for the next person, and, I also believe, as I believed 30 years ago, that the doctors really don't know all the causes of what they put in their catch-all "rosacea" diagnosis. There are countless bacteria that doctors don't know a damn thing about. Yes h.pylori was the focus of the Australian doctor/researcher's study, however, that doesn't mean there aren't countless other bacteria being effected, either ridding some and/or boosting others, by the antibiotic combos he suggested, or, by the copious antibiotics thrown at me in my life before my "rosacea."

Looking back, after living through this covid bs, it seems a distinct possibility that ivermectin may have been all I would have needed to end my case of "rosacea."

Mine did.
