I have a question about how to get rid of adult acne.

I've had chronic adult acne for years, and it's so bad I hate looking in the mirror.

Inflammatory acne occurs repeatedly, mainly around the chin and mouth, and once it occurs, it does not go away easily and if touched incorrectly, it often ends up leaving scars or dark pigmentation.
I've heard that irregular lifestyle habits, stress, and hormonal influences are the causes.

I would like to request information on how to get rid of adult acne and how to treat it.
As I am considering the procedure, I am curious about the following three things:
I would appreciate it if you could provide me with some information.

1. I would like to know what treatment is effective for treating adult acne and how to get rid of acne.

2. I'm curious about how long acne treatment should take, and how long the results should last after the acne subsides. This will be an important reference point when deciding on a treatment.

3. Information on returning to daily life (most important): Will there be any noticeable external signs, such as bruising or redness, after the procedure? In other words, I'm most curious about whether I can return to my daily life (such as going to work) immediately after the procedure.
