Which laser is best for my condition?

I had pretty severe acne bout year or two ago. I was on accutane and that cleared up the acne but now i have acne scars that look red. My face from time to time turns red from flushing and stays lightish red. nothing too severe like bright red or anything. Basically i was wondering exactly which laser would emit the redness? Pulsed dye laser, or the IPL laser? I was recommended IPL by one derm and PDL by another. Please any help?
