How do I find "acne scar specialists"?

I read a lot online about how people said they should've went to an acne scar specialist instead of dermatologist earlier. However, I searched "acne scar specialist near me" but I can't really tell if a place is a general dermatology clinic that offers acne scar services or an actual acne scar specialist. Is there a certification or website that I can use?

Edit: based out of Howard County area in Maryland
