Olivia Munn knows her face has changed a lot in the last year, but she said it’s not because she had plastic surgery.

The 35-year-old actress posted a side-by-side photo on Instagram late Tuesday to clear things up after fans suspected she had gone under the knife. (RELATED: Olivia Munn Just Revealed Whether She’s Engaged To Aaron Rodgers)

“Ask anyone who knows me and they’ll tell you I love research,” Munn wrote. “Convinced that there’s got to be natural, healthy ways (i.e. not only the rich and connected can do it) to keep your skin from aging, I do lots of research.”

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. Who says guys are the only ones who can get better with age? We're gonna turn that myth around if we share what we learn with each other. So here are 4 skin tips I've learned just over this past year that really helped the texture and shape of my face. Left Pic: 1 year ago. Right Pic: Last month. 1. 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. Working out is also great for your skin because it increases blood flow to your face which helps rejuvenate. 2. Reshaped my brows. 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. 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. 3. Got rid of sunspots. I love my freckles. But over the past couple of years I've seen more come up and merge with other freckles to make large dark spots. Dark spots prevent your skin from reflecting light and gives you a dull complexion. So for the past year I've been diligently using @Proactiv Mark Fading Pads. 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. 4. I've talked about this before and I still stand by it: Japanese potatoes that are high in Hyaluronic Acid help keep wrinkles away. Look up this video: "Connie Chung Yuzihara" to learn all about it. There are Hyaluronic Acid pills and vitamins but I think that the best way to get it in your system is by eating them in foods that naturally have them. I'm still looking into what gets rid of the lines that develop around your neck. I think it has to do with tension and acupuncture might be the answer. When I find out more, I'll let you know.

Munn then said her jawline had slimmed up because she lost 12 pounds, said she reshaped her eyebrows, use facial pads that got rid of her sunspots and ate a lot of Japanese potatoes. (RELATED: Olivia Munn Is A Sword Slinging Bada** While Aaron Rodgers Kind Of Just Stands There)
