Will acne treatments definitely be effective?

Strangely, my acne just won't go away even as I get older.

I always pop my acne at home, and maybe that's why I've gotten scars, so I'm wondering if I should go to a dermatologist.

Would receiving professional acne treatment be effective?

Also, once I start acne treatments, do I need to visit periodically?

I'm also really curious about the cost of acne treatment.

Is it possible to get acne treatments at a regular hospital?

Or I'm wondering if it would be better to get it done directly at a professional dermatology clinic!

I'm worried that the cost of acne treatments will vary too much from hospital to hospital.

Also, for those who received acne treatments, was it cleanly removed without any pitted pores or traces?
