Has anyone experienced the effectiveness of acne treatment?

My skin condition has been deteriorating rapidly lately, and I am very worried because breakouts keep popping up. I feel like home care alone has reached its limit, so I am looking into professional dermatological care. I have become interested because many people around me have recommended acne treatment.

For those who have actually received acne treatment, I am curious to know how many sessions it usually took to see noticeable results. I would also like to know the level of irritation or pain during the procedure and how the follow-up treatment schedule is typically set.

For those of you who have personally received acne treatment, could you please share your satisfaction level, honest reviews, and aftercare tips?
