I'd like to know the approximate cost and treatment time for acne treatment!

I am under a lot of stress lately because my adult acne has suddenly gotten much worse. I tried squeezing them out at home, but it seems like the scars are only getting darker, so I am planning to seek help from a professional dermatologist. Since guidance varies slightly from clinic to clinic, I am posting this question to get some general information beforehand.
I am curious about the approximate cost range for acne treatment at a dermatology clinic. Is there a significant price difference between receiving only extractions and undergoing combination treatments such as anti-inflammatory injections, scaling, Gold PTT, or sebaceous gland destruction lasers?
Also, since I cannot stay at the dermatology clinic for a long time due to work, I would like to know how long I should typically allow for acne treatment on weekdays.
As a working professional, I want to use my time and budget efficiently. I would appreciate advice from those with actual experience or expertise. Thank you!
