Hello! Until a doctor can answer your post, I can provide my own limited info, if you'd like.
Did he mention which laser type he would use? I know for a fact that with IPL, you need 4-6 treatments, and it does hurt a bit as they raise the power level. Even with a numbing cream, it kinda hurt, nothing horrible, just a snapping, like a rubberband. And honestly, it didn't do that much for me, rosacea-wise, except for the 1st and 3rd treatment. After those two, I looked great, for some reason. My skin was incredibly smooth everywhere else too, the non-rosacea areas. If I did have the money, I would give it another try, while avoiding triggers, being "good", using Metrogel and Oracea, and perhaps I would have different results. I might in the future go again, or maybe for the YAG. I haven't decided.
I think the YAG laser is painful, but I'm not sure how many treatments you would need, ie, if it's a small area would one suffice, or more? I have a freckle on my hand that the derm offered to blast with the YAG, and he said one time would work, although it would be quite painful. quote-unquote.
There are a few members who have had the YAG, all over I think, and they required multipe treatments.
