Do I have a rash on my breast or are they glands of some kind?

Do I have a rash on my breast or are they glands of some kind? For a few months now, I’ve noticed this pink/red patch just outside of my areola. It doesn’t hurt or bother me in any way. I assumed it was glands. I added a photo of it to another doctor site just to see, and the dermatologist there seemed pretty confident that it was folliculitis and told me to get OTC cream or see my PCP for antibiotics. I’ve used the OTC stuff for 2 days now with no improvement.
