Acne scar problem

I am a 25-year-old woman. I have been spending a lot of money on acne treatment, but now I am applying ointments from the pharmacy. Usually, I have difficulty healing because I need to write papers, and I feel pressure and anxiety from daily life. I also suffer from severe insomnia, and acne tends to appear mainly on my forehead. Since I need to undergo treatment temporarily for an event, I am looking into dermatological procedures. My budget is around 80,000 won per session. I want to find a dermatology clinic in Seoul that specializes in acne treatment. I live in Jung-gu.
