Yes, I have used a Yag laser. It was a 1064 um cool glide yag laser. It was still in expermental try outs so yes it did scar. But I only did a testing area of seven zaps. Yag laser are more aggresive then Pulse Dye lasers but have been known to scar also. PDL do not. It really depends on your type of PWS, how it reacts to the laser, and the doctor and how he/she sets up the machine. I would suggest asking Dr. Nelson what his opinion is on the laser you are thinking about using. He is the Ask the PWS expert on the home page of this website. Make sure you know the exact kind of Yag laser you want to know about because there are more then one.
The Yag has a higher risk of scarring....but new devices are out...so good to find out from your doctor what options are available. The reason pulse dye is so popular is the lower risk of scarring with the cooling jets.
