How should I schedule my acne treatment?

My skin is usually fine, but on days when I'm not feeling well or haven't slept properly, I tend to suddenly get multiple breakouts on my chin or forehead. Once it gets worse, it takes a long time to calm down, and since new acne keeps popping up just as it starts to subside, I am looking into acne treatments.

However, I am wondering how often I should visit once I start acne treatment. I would like to know if treatment is required whenever acne flares up, or if I need to continue with the set schedule even after my skin has improved to reduce the risk of recurrence.

Due to my work schedule, it will be a bit difficult to visit every week, so I am wondering if there is a strict schedule I must adhere to to see the effects of the acne treatment. I would also like to inquire if the intervals between visits can be gradually increased as my skin condition improves, or conversely, if it is acceptable to visit earlier than scheduled if inflammation suddenly worsens. I am also curious if you determine the appropriate acne treatment method and frequency based on my skin condition during the initial consultation.
