In an Instagram post comparing two photos of herself from one year ago and one month ago, Munn, 35, shares her anti-aging secrets.
"Ask anyone who knows me and they'll tell you I love research," the actress writes in the post on Tuesday. "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."
Munn – who undoubtedly looks younger in the photo from this year – then went on to share four beauty tips that "really helped the texture and shape of my face."
"1. I lost 12 pounds this past year while training for Xmen," she says. "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. Working out is also great for your skin because it increases blood flow to your face which helps rejuvenate."
The Ride Along 2 star also credits reshaping her brows for her refreshed look.
"I do my own brows and always thought they were supposed to have a high arch. Then a facialist pointed out to me that I was shaping my brows into a frown," she reveals. "So 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."

Munn's final skin tip is not as traditional: "Japanese potatoes that are high in Hyaluronic Acid help keep wrinkles away," she says. "There are Hyaluronic Acid pills and vitamins but I think that the best way to get it into your system is by eating them in foods that naturally have them."
And Munn isn't about to stop there. She's still researching and looking for ways to prevent neck wrinkles.
"I think it has to do with tension and acupuncture might be the answer," she says. "When I find out more, I'll let you know."
