Researchers at 23andMe, a genetic testing service, compared the genes of over 34,000 men and women to their answers to a survey about stretch marks. This information helped pinpoint a genetic marker associated with the development of said marks. “This research could lead to better treatments,” says Joyce Tung, PhD, and author of the study published in the Journal of Investigative Dermatology. “But my other hope is that women will come to accept their stretch marks—it’s genetic, so there’s not a whole lot you can do.” Sorry to be the bearer of bad news, but it’s official: you can’t prevent ‘em. Need a new plan? Don’t beat yourself up over your next stretch mark, come to terms with the ones you have, and focus on things you can control, like treating your skin (and body) with acceptance.
