How long does an acne treatment cycle usually take?

My skin, which I thought would get better after becoming an adult, continues to break out periodically, so I have finally decided to get proper treatment. I think squeezing or touching my pimples on my own is leaving marks, so I am looking into proper acne treatment. I am curious about the typical treatment schedule. I would like to hear opinions from those with experience on whether I need to go consistently once a week or if it varies depending on my condition. I would also like to know in advance roughly how much the cost of acne treatment can be. While it will vary depending on skin type and the severity of the breakouts, please feel free to share any general guidelines or care tips you may have!
