And the science totally backs her up.

Shailene Woodley has made it known she's all about that ~natural~ lifestyle. You're more likely to catch her raving about plants than injections or chemical beauty treatments, and her latest endorsement went to a natural treatment that's been around for ages: mud baths. She recently shared a photo on Instagram of herself taking a soak. (Check out these other celeb beauty treatments we totally want to try.)

She didn't mince words in her endorsement, captioning the photo "bathe in mud. do it. DO it." And while you might want to think before sunbathing your vagina, this time around you should definitely take her advice. Mud baths have multiple skin benefits. "Most mud baths are made of volcanic ash that can exfoliate the skin, sloughing off dead skin cells and leaving it much softer," says Lily Talakoub, M.D., of McLean Dermatology and Skincare Center. The minerals in the volcanic ash also help to balance out the skin's pH. If visiting a natural hot spring with mud isn't in the cards (P.S., here's where you can take a "hot spring" break vacation) you can also likely find these same volcanic ash mud treatments at your local spa. If you go the spa route, Dr. Talakoub suggests choosing a warm mud bath treatment over a cold one, since warm treatments have added anti-inflammatory benefits and increase circulation.

The benefits of mud baths aren't just skin deep, either. Unsurprisingly, soaking in warm mud is known for being especially therapeutic. One study found that taking mud baths helped to reduce the symptoms of patients with arthritis. Who knew?

There are also plenty of mud mask products designed to have the same pH-balancing and anti-inflammatory effects. Dr. Talakoub suggests Elemis Herbal Lavender Repair Mask ($50; or Garnier Clean + Pore Purifying 2-in-1 Clay Cleaner/Mask ($6;

TL;DR? Based on all the benefits and Woodley's enthusiasm, you should definitely give mud a try.
