F29 166 cm 65 kg , Tried multiple dermatologists, cystic acne keeps returning—should I see a gyno or endocrinologist?

I’ve been dealing with PCOS, and cystic acne is basically my only symptom. My periods are regular, and I don’t have body acne—everything shows up on my face, and it’s honestly been really hard to deal with.

I’ve consulted multiple dermatologists, and they usually prescribe isotretinoin. It works while I’m on it, but once I stop, the acne comes back again. I exercise regularly, walk, and maintain a decent diet. My weight has been increasing slightly, but nothing too concerning.

At this point, I’m confused about what to do next. Should I consult a gynecologist or an endocrinologist? Has anyone been in a similar situation? Any advice would really help.
