I would like to know the price and duration of one acne scar treatment session.

I am looking into acne scar removal procedures, and I found that there are more types of treatments than I expected, with quite a significant price difference. I am most curious about the cost per session and how long the procedure takes. What is a typical budget for acne scar treatments? I am very busy these days and don't have much time, so I would like to know if the procedure itself is relatively short or if it takes longer if anesthesia is included. Since the price and duration might vary depending on the depth and location of the scars, I am also curious to hear the experiences of those who have actually undergone the treatment. I am concerned about whether I can go out or resume daily activities immediately after the procedure, so it would be very helpful if you could also tell me about the level of swelling and pain. I would also appreciate it if you could share the extent of scar improvement and how many sessions you have received.
