Post inflammatory erythema or red acne scars? (Photos)

I believed what i am having is post inflammatory erythema which stays for years. It can get redder in colder or hotter temperatures. Which laser can i do to get to normal skin appearance? I did two sublative rejuvenation and it didnt show much improvement. This picture was taken 1 month post 1st treatment. Post 2nd treatment looks worst. Is V-beam the only choice u have? I live in dunedin new zealand where there is no v beam at all. The only alternative i found are IPL or VPL. Can these do much good?
