What's the Best Laser Treatment for Acne Scars and Large Pores?

I had one session of Fraxel a few weeks ago and had white patches all over my face afterwards. Also Dr. refused to do in between eyebrows and when I asked him why he said just didn’t. I have acne scarring and I’m afraid scars may become larger if I don’t continue to do something! The problem is, there are so many lasers and too many doctors selling their own products. How should I make that decision? Which laser best for making acne scars and pores smaller? My face was hardly red the next day, which made me believe the procedure was underdone. What is your opinion? I could also go back to using Retin-A the next day. Please give me some input for I have another appointment this Tuesday. I’m wary about the types of lasers and about this particular doctor. At $1,100.00 per session, I can’t afford to just waste it! Thank you for your time!
