When is a person typically treated for acne?

I keep getting recurring acne, so I'm considering getting a treatment, but I'm not sure if my case qualifies.

I'm wondering if there are specific people or times recommended for acne treatment.

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 treatment isn't something just anyone can get, I want to know first if it's suitable for my skin condition before starting.

I'm worried that I might make the wrong choice and make things worse, so I'd like to know the criteria. I'd appreciate it if those with experience could share their recommendations.
