Hi COB. For red stretch marks, we would seek out a practice that uses pulse dye lasers. Pulsed dye lasers (V-Star, V-Beam) are used to close the small blood vessels that make the skin appear red, like the ones you have in the stretchmarks. 2-5 treatments in a series over a period of several months should help you resolve the issue relatively quickly.
See the before and after photos at the link below of a Los Angeles, CA, red stretch mark patient before and after these laser treatments. Good luck.
