Very small cysts continuing to appear on Ears. Can’t find cause!

I am 185 lb early 20’s male. I do not have acne, but I do have cysts that are appearing in my outer ears. It is ramping up and they are very small but it went from 1-2 to 5-6 between the left and right ear and I’m wondering if accutane or any other medicine out there could potentially help this issue. Previously I had a small one drained and they believed that it was potentially sebaceous but unsure.
