Let’s face it: As we get older, our breasts don’t sit up as nicely as they did when we were in our 20s. You can blame their loss of elasticity and the pull of gravity. But many things factor into when and how much sagging you’ll experience, including your genes.
“The strength and integrity of your breast tissue are primarily coded in your DNA, which comes from your parents,” says Ryan Neinstein, MD, a plastic surgeon in New York City. So looking to your mom may give you a clue of what to expect.
Significant weight changes, whether gain or loss, can also contribute. So can smoking and other habits that lead to loss of elasticity in the skin, such as sun damage.
