Treatment options: Fractional laser resurfacing, in which a laser damages tiny columns of skin, creating hundreds of microscopic wounds to boost collagen production, has been shown to help the body heal stretch marks.
In one recent study, doctors harvested patients' fibroblasts, multiplied them in the lab, and reinjected them in high quantities into areas affected by stretch marks. There was moderate to significant reduction in the visibility of the marks.
In another study, a IPL laser, used in combination with Thermage (a radiofrequency collagen booster), showed "good to very good" improvement in almost 90% of patients.
Surgical treatments: The tummy tuck, a surgery that removes excess skin in the stomach area, often also takes away stretch marks caused by pregnancy or rapid weight loss.
