Deep in the skin have red pigmentation - what is the best way to clear this? (photos)

It's been treated several times by yag laser 1064. It's gotten better through such treatments but the treatments always result in my skin blistering very badly and in some cases leading to scarring. When the doctors use the laser on the lowest setting it doesn't treat the redness. At higher settings it get's the redness to clear but causes the blistering and scarring. I really appreciate any advice or ideas on another form of treatment
