Olivia Munn Swears By This Food For Anti-Aging

There are about twice as many celebrity skincare tricks as there are celebrities out there. Heck, Kourtney Kardashian even features new beauty items every month on her Poosh website. It's overwhelming to say the least. While there's definitely nothing new about hearing how celebrities get glowing skin, Olivia Munn's skincare hack is a whole lot different than the rest (via Showbiz Cheat Sheet). Actually, it's tastier too. 

Celebrities spend an incredible amount of money on their skincare items. It's investing in yourself and there's definitely no shame in that. It just does make it easy for the rest of the world to keep up. But Munn is not giving out her favorite brand or telling people about a new fitness routine that she's on board with. This time, she's telling us her grocery list.

It turns out that there's one food item that has as many skin benefits as your nightly serum. Oh, and they're less than $5 on Instacart. Here's everything you need to know so you can add the item to your grocery list and skincare routine all at the same time.

Go ahead and put your credit card away, because Olivia Munn's beauty secret is simple and will take you right back to the basics. According to Showbiz Cheat Sheet, Munn eats Japanese potatoes as a part of her skincare routine. Yes, you read that corectly.

The actress says that the potatoes have a secret ingredient that you might recognize as a staple skin ingredient — hyaluronic acid. "I've talked about this before and I still stand by it," Munn says. "Japanese potatoes that are high in hyaluronic acid help keep wrinkles away." That's the exact same ingredient that you likely already have in your skincare routine.

Hyaluronic acid occurs naturally in the body and is mean to keep the tissues of your skin lubricated and hydrated, according to Healthline. Because it's a naturally occurring ingredient, it's also found in the Japanese potatoes. The big catch is that you're ingesting it, instead of rubbing it on your skin.

Don't think that you're going to be munching on french fries every morning and night though. The Japanese potato has a much different flavor than your typical russet or sweet potato. The type of potato that Olivia Munn munches on is sweeter than your typical potato and tastes more like a roasted chestnut than a french fry (via Just One Cookbook).

Actually, it's so sweet that Munn eats the potato as a dessert. "I'll take one sweet potato, slice it into one-inch-thick slices, and then dust it with olive oil and cinnamon, put it in the oven, and do that as dessert. I'll eat those as often as I can — a couple every day." That might not be your traditional skincare routine, but there's nothing wrong with a nightly snack in the name of better skin.

According to Well+Good, baking the potatoes and sprinkling them with cinnamon is actually a really common way to eat the potato. The publication also suggests whipping them into a type of mashed sweet potatoes or baking them into bread. No matter how you cook it, you're still getting the added bonus of hyaluronic acid. 

Of course, just like any other skincare product, simply adding these potatoes into your daily meals isn't a fool-proof way to better skin. While nutrition does play a role in healthy skin, you'll also want to make sure that you're hydrating as well (via Premiere Health). Jennifer Levine, New York-based plastic surgeon, tells Us Magazine that while adding Japanese potatoes into your diet is good, it's not a quick fix. 

"The health benefits of consuming these potatoes could be great, but their effect on antiaging would be very small at best. Ingesting the acid would cause it to break down in the digestive system, and it wouldn't get to areas such as the face in high enough quantities to cause a real difference," Levine tells the publication. "There are no negative effects to someone's appearance, but no one should expect to see [dramatic] results."

Of all the different skincare tips out there, this is by far one of the most delicious.
