DDP in Vancouver

Why does it cost twice as much as the USA ? One Dr quoted me $ 600 per session. Seems like the cheapest is $ 500, yet other countries are only paying $ 100 - 300 per session. Would have been worth it a year ago when our dollar was even, now....i am not sure if it's worth it since our dollar has gone down...anyhow..i am so happy i found this site. When i went to the two doctors who showed me before and after pictures, i didn't see much of a change. I felt that if i were to spend $ 2,500 for 5 sessions, my skin better be perfect. It also seems like the pictures of before are taken in different light than the after shot. i was told that i would have great skin in 3 sessions as i only have mild roseca, some freckles, some redness, and some blister like moles that never go away. I am considering only doing one treatment. From all the posts i read, most people either see results after one session, or don't see results. But hardly anyone gets burnt in one session. Should i bother ? it's around $ 500. Anyone from Vancouver, Canada that can reccommend someone who knows what they are doing ?
