How should I take care of my acne-prone skin?

I have been struggling with acne for a long time. I thought it only happened during puberty, but even now that I am an adult, it keeps popping up. It causes me a lot of stress because as soon as one clears up, another one appears in a different spot. In particular, the red, inflamed acne leaves marks, making my skin look increasingly messy, which is lowering my self-confidence. I usually wash my face thoroughly and use acne-specific skincare products, but I haven't seen as much effect as I expected.

I am considering getting dermatological treatments, but there are so many types that I am not sure which one is right for me. I am wondering if getting just extractions is sufficient, or if I need to combine them with treatments like lasers, scaling, Aqua Peel, or PDT for better results. Also, since my skin tends to be sensitive, I would like to know the extent of redness or side effects after the procedure, and how many sessions are required to expect noticeable changes.

I would also like to hear from those who have actually undergone acne treatments about which procedure they were most satisfied with and how the results were compared to the cost. Please recommend any treatments that help reduce acne while also preventing scars and marks.
