What is Cool Laser Resurfacing and how is it different from the rest?

Recently heard about this specific type of laser treatment, and hoping to get a breakdown on exactly what it is. What I mainly need addressed are these hideously large pores on my cheeks, next to that would be my slightly bumpy facial terrain and last, but certainly not least, scarring. I've already tried a chemical peel and microdermabrasion. They were nice but didn't really give me any results worth noting. Please help!
