I would like to inquire about a consultation regarding acne treatment. What is the recommended number of sessions?

Lately, I have been experiencing frequent breakouts, and once acne appears, it doesn't subside easily, so I am considering acne treatment. In the past, it would naturally get better over time, but lately, the marks linger and recurring in the same areas, so I am reaching the limits of managing it on my own.

I am looking into acne treatment, but I am wondering if I need to get a diagnosis first to determine which procedure is suitable for my skin condition. I would also like to know if improvement is possible with extraction alone, or if combining it with lasers or other treatments yields better results.

And the part I am most curious about is the recommended number of sessions. I would like to know how many sessions you generally recommend for beginners. I assume it varies depending on skin condition, but on average, how many sessions are needed to expect noticeable changes, and how often should I visit?

I am also curious if there are any special precautions I need to take in daily life, such as washing my face, applying makeup, or exercising, while receiving acne treatment. I would also like to know if I can apply makeup immediately after treatment, and how I should manage sun protection and moisturization.
