Acne treatment effects

As acne keeps breaking out repeatedly, I have reached the limit of managing it on my own, so I am looking into acne treatments.

I am most curious about how effective acne treatment is.

There is a lot of information on the internet, but I am concerned because there aren't as many real-life experiences as I expected.

My skin is on the sensitive side, so I want to receive treatment that isn't too irritating. For those of you who have started acne treatment, when did you start seeing results?

I am curious if the redness or skin texture has also improved.

Since the methods vary from hospital to hospital, I am also struggling to decide what criteria to use when making a choice.

If you have received the treatment yourself, it would be very helpful for my decision if you could share whether you were satisfied with the results and what you experienced during the process.
