Are there any programs that can help manage adult acne and pigmentation?

Even during my teenage years, I didn't know what acne was.

When I turned 30, my skin started to change.

Since then, I've been getting a lot of acne and pimples under my chin.

If you keep touching it, it will become scarred and pigmented.

I'm wondering if there are any treatments that can help manage adult acne.

I'm also curious about lasers that can manage pigmentation.

Price and number of treatments

I would also like to know the treatment period, etc.

Now that I have adult acne, it really is ㅠㅠ It gets worse when I have my period

I want to go back to the past

What kind of laser treatment would be good for pigmentation caused by adult acne?

Thank you for your reply
