They’re unsightly, hard to erase, and a telltale sign of weight gain or loss. But why are some women more prone to stretch marks than others?
Research shows that women with stretch marks have a pronounced deficiency of total DNA and protein in the skin, and they are slower to repair stretch-dependent skin injuries; hence the formation of stretch marks. When the skin is over-stretched at a particular area, the fibers in the elastic middle layer of the skin tear, causing stretch marks to develop.
It’s hard to find heredity, but regardless of your genetic makeup, stretch marks may be preventable. Your best bet? In times of weight fluctuation, keep skin hydrated with intensive moisturizers.
