I've gotten these flare-ups for years. My skin is flawless, and then it begins getting rough and flaky, always around my nose on the sides:  Images. It may get red after because anything at that point irritates it. The following day, the redness goes away, but the skin feels hard and flaky, and it can be itchy at times.

I don't think it's related to anything I use on my face bc I've had it for a few years and I don't really wear makeup there, it's rare. Lately I haven't used makeup yet it's flared up. I'm posting here bc I have gotten different diagnosis: A clinic Dr diagnosed me in years ago with Seborrheic Dermatitis who said it could be from my pup. Recently, an online physician diagnosed it as Perioral Dermatitis from the pics showing the redness. I was prescribed Metrogel 1%, Azelaic Acid cream 20% and Clindamycin 1% which may work yet may not be the best treatment if it's seb derm.

Does it look like Seborrheic Dermatits, Perioral Dermatitis, or something else?

Also, what's the best treatment to request for the RX?
