I got two consultations for laser treatment from two different dermatologists in order to remove purple/red stretch marks which I got after weight loss. The first doctor recommended Candela VBeam Dye pulse laser: the second doctor recommended Icon 1540 Cynosure laser. Which laser among these two options is the best for purple/red stretch marks? The priority is to remove the purple from these marks as soon as possible, I want them to turn white faster. It has been 6 months. Thanks!
