Miranda Kerr Reveals Her Simple -- and Inexpensive! -- Way to Prevent Stretch Marks

Model Miranda Kerr has the resources and cash to keep her skin in tip-top shape, but she says keeping her skin soft, supple -- and stretch mark-free -- during her pregnancy is just as attainable for any woman.

"Actually, I used the rosehip oil throughout my entire pregnancy and I don't have a single stretch mark -- I had a ten-pound baby!" she tells Into the Gloss in a new interview. "It's really nourishing and full of antioxidants and essential fatty acids."

This isn't the first time we've heard of this remedy -- and proponents of rosehip oil claim that rubbing copious amounts into the skin on a daily basis will keep all stretch marks at bay.

Does it work for every woman? Not necessarily: The American Academy of Dermatology says that 90 percent of women experience stretch marks during the sixth and seventh months of pregnancy.

Many doctors believe that stretch marks are at least partly due to genetics, but you can decrease the chances that you'll get them with a few prevention methods.

Eat a Healthy Diet

A well-balanced diet can keep your organs -- including your skin -- healthy during pregnancy. The Cleveland Clinic says that eating a diet full of zinc-rich foods (like nuts and fish) can help keep stretch marks at bay. Foods high in protein and vitamins A, C and D help, too.

Apply Lotions with Vitamin E

A study of 100 pregnant women published in The Cochrane Database of Systematic Reviews in 2000 found that those who applied alpha tocopherol, a form of vitamin E, reported fewer instances of stretch marks than those who didn't apply it.

What didn't work? Cocoa butter. A 2008 study of 175 women found no difference in those who applied the cream and those who used a placebo.

Avoid Caffeine As Much as Possible

Well-hydrated, healthy skin is less likely to develop stretch marks, according to the Cleveland Clinic. The reason: It's more pliable than dry skin, meaning it won't tear as easily.

And if you can't give up your tea, soda or coffee? Just make sure you balance it out with plenty of water.
