At what stage do people usually get acne treatments?

I keep getting recurring acne, so I'm considering getting a treatment, but I'm not sure if my case applies. I'm wondering if there are specific people recommended for this procedure or if there is a particular time for it.

I would like to know if this treatment is better suited for people with a lot of inflammatory acne, or if it is also effective for comedonal acne. Since acne treatments aren't something just anyone can get, I want to know first if it is right for my skin condition before I start.

I'm worried that I might make the wrong choice and worsen the situation, so I'd like to know the criteria. I would appreciate it if those with experience could share their recommendation standards.
