I'm curious about the cost, effectiveness, and price of acne treatment.

I’ve suddenly had a lot of breakouts lately, so I’m considering getting acne treatment. My skin has broken out before, but this time it isn't subsiding easily, which is causing me a lot of stress. For those who have received acne treatment, was it actually effective? I’m also curious if there is a significant difference in treatment prices between different dermatology clinics. I’d like to know how many sessions are needed to see noticeable results. I’m looking into various options because I’m worried the cost might be higher than I expected. Are there any places or methods that are effective without being too expensive? If you could also share the prices, I’d like to use them as a reference when looking into further options. Thank you in advance for your answer.
