Olivia Munn gave fans some major insight into her beauty routine on Instagram Feb. 23, sharing why her face might look different. Among the reasons she lists? Potatoes!

The 35-year-old actress posted an informative caption underneath a side-by-side of her face last year compared to her face last month. There are obvious changes between the two photos, and the actress got candid and accounted for all of them.

To kick off her explanation, the "X-Men" star began with the reason behind the post, "Ask anyone who knows me and they'll tell you I love research. Convinced that there's got to be natural, healthy ways (ie not only the rich and connected can do it) to keep your skin from aging, I do lots of research."

She goes on to cite weight loss as the first explanation for the change, writing, "I lost 12 pounds this past year while training for Xmen. I kept it off by coming up w/an hour workout I do a few times a week. The weight loss leaned out my cheeks and jawline."

The next didn't involve losing weight, but this minor adjustment to the face made a big difference -- she reshaped her eyebrows. "I let the top of my brows grow in (which is never fun because it looks spotty for a few weeks) and then I plucked the bottom. That gave my brows a more horizontal angle and instantly brightened my eyes," Olivia shared.

The difference in the amount of freckles between the pictures is striking, and Olivia added that to her list as the third change, "Got rid of sunspots." While she confessed that she loved her freckles, she was plagued by dark spots that were dulling her complexion. For helping with that Olivia credited Proactiv Mark Fading Pads, sharing, "I wipe my face with one every night and now my face has a more even tone and the large spots aren't as noticeable."

Olivia's final reason is the most surprising -- and mind boggling. The gorgeous actress credited potatoes for helping her look younger, explaining, "I've talked about this before and I still stand by it: Japanese potatoes that are high in Hyaluronic Acid help keep wrinkles away." She advised fans to check out a video where Connie Chung reports on the miracle food, and gave the potatoes credit for providing a natural source of Hyaluronic Acid.
