Old White Indented Stretch Mark Laser?

Its hard to give you a definitive answer without seeing you in person and knowing what the lesion looks like. I would recommend you see a board certified dermatologist who has expertise in lasers. Most laser experts have both types of technology and will select the one most suited for the patients. If you get into a situation where people only have one or the other type of laser, they sometimes tend to overuse that laser. Good luck.
