What kind of trouble treatment are there?

hello.

I'm contacting you because I had acne on my face and although it has subsided, there are still a lot of scars left.
These are mostly dark pigmentation(?) caused by touching the skin incorrectly after a pimple appears.
I'm worried because it doesn't fade as much as I thought it would even after time passes.

Even if some of them fall off, they come up again and again in the troubled area,,, so I think the color becomes darker.

Currently, I am managing my scars with basic moisturizing and UV protection ointment.
I'm considering getting treatment because I feel like self-care alone has its limitations.

In the case of these trouble marks

• What types of treatments can help?

• What are some treatments that are relatively less invasive for the skin?

• The price is also affordable

I want to know.
Please reply. Thank you.
