My acne keeps recurring. Can a procedure resolve this?

After getting PicoFraxel, my acne marks seem to be improving little by little, but the problem is that new acne keeps popping up.

I wash my face thoroughly, cut down on greasy foods, and try to take care of myself, but it keeps breaking out periodically. It seems to get worse when I'm stressed, and I'm frustrated because I can't figure out the root cause. I'm also wondering if it's possible to get a consultation or tests at a dermatology clinic to identify the actual cause of the acne.

I would also like to know if there is a way to reduce the recurrence itself through a procedure. I saw a post saying that Potenza is effective not only for acne scars but also for preventing recurrence, so if anyone has actually found it helpful, I would appreciate it if you could share your experience.
