Acne..., ampoule, is there a treatment method?

Ahhh~~

I am a working adult who has a hard time because of acne that continues even after becoming an adult.
Even with extrusion and basic management, it only lasts for a while, and after a few days, the inflammation comes back, so now I'm thinking about fundamental treatment.

I am curious whether the ampoules and treatments that many people use are effective in preventing acne recurrence.
In particular, to what extent are there treatments that directly control sebum glands or ampoules that help skin regeneration?
And I'm curious about how many times it takes for my skin to stabilize.

Please let me know if you have any post-procedure precautions, washing routines to prevent acne, or lifestyle tips.
I really want to get rid of these annoying acne.
