How many sessions should I usually expect to need for acne treatment when I start?

I'm the type of person who checks how many times I have to do something before I start anything lol
I found that my mental preparation changed completely depending on whether I did it once or twice and then stopped, or if I had to do it consistently for a few months.

Lately, my skin keeps fluctuating between getting better and worse, so I'm thinking about getting proper acne treatment. I feel like there's a limit to just using soothing products and being careful with cleansing at home.

However, when I looked up the recommended number of acne treatments, the information varied so much from person to person that it made me even more confused.

Some people say they definitely felt more comfortable after just a few sessions, while others say they went consistently for several months. Is it true that there is a big difference depending on skin condition?

I am curious if, during the initial consultation, you tend to assess your current skin condition and explain approximately how many acne treatment sessions would be suitable.

Rather than making a long-term plan from the start, I’d like to try it out once and continue if it’s good. Would it be okay to start that way?

Also, I was wondering if it is possible to receive treatments at regular intervals initially and then reduce the frequency once my skin stabilizes.

I would like to know if the same care is repeated every time, or if the necessary details change depending on the condition of the skin.

There are days when my skin is extremely sensitive, so rather than strictly completing the set number of sessions, I would prefer to adjust based on my condition that day.

For those of you who have received acne treatment five or more times, at which session did you feel a definite difference?

I'm also curious if there was a change from the first episode, or if you felt that the frequency of new uploads decreased after a certain amount had accumulated.

Also, once it has improved to some extent, I would like to know if it is okay to rest completely or if occasional maintenance is necessary.

My goal is to reduce the recurring pattern rather than having completely clear skin, so I am most curious about the realistic recommended frequency.

For those of you who have consistently received acne treatment, please share your experiences regarding how many sessions you actually took to be satisfied.
