Asian Acne Scar Removal - What Works Best for Dark Skin?

I am looking for a treatment that's affordable. My pores are getting larger the older I get and I would like to prevent this from increasing. I have old acne scars and reccuring mild acne breakouts, which I believe is the combination of food and stress. I went back to the states, from Korea, for a one month vacation and was able to see the quick change in my skin return to an acne-free skin. I am a vegan and I excersize 3-4 times a week.

What treatment would work best for my acne scars?
