I have had some type of skin reaction on my right upper lip area. This has been going on for many weeks now. I went to see my dermatologist and he recommended I apply a mix of mometasone furoate and ketoconazole cream because the area is red and seems inflamed but is also flaky (possibly from a yeast infection). I have been using this for 1 week now and have seen some improvement. My concern is that I think some spots are not flaky and only inflamed so I don't know if a mix could have any negative effects on those areas such as increased redness. Does anyone have experience mixing these?
