Are there any side effects from acne treatment?

I have had acne-prone skin since childhood, so even after becoming an adult, I am still struggling with small pimples.

During my teenage years, I used to travel all the way to Seoul from the countryside to get peeling treatments and pop acne to remove scars, but the treatments only provided temporary relief. Acne kept popping up, scars formed, and my pores widened.

Then I became an adult, but my skin didn't improve and was left with only acne scars.

I want to try the acne treatment again, but now I am worried about the pain and side effects.

I remember my pores getting wider after an acne treatment.

I am curious to know what acne treatments everyone received and what results they saw. I am also curious about whether there were any side effects and the cost. I want to live with smooth, clear skin with no visible pores.
