Dermatologist recommendations for adult acne treatment

I frequently get pimples even when it's not my menstrual period.

I'm worried because it's painful and the face is very visible in my eyes.

Just sticking on an acne patch doesn't necessarily mean it'll work.

I went to the dermatologist before.

It costs a lot, and it only gets better during treatment, but if I don't go to the hospital, it comes back againㅜㅜ

Please recommend a good dermatologist in the Gwangju area.
