Olivia Munn took to Instagram on Tuesday to explain in detail why her face looks younger after some fans started pointing out that her appearance has changed lately.

The 35-year-old actress shared two photos of herself side-by-side, comparing just how different she looks from one year ago and one month ago. Fans had been questioning her altered looks lately, and this might have been what triggered her to not only post the comparison photos but share her anti-aging secrets as well, according to Us Weekly. 

When she posted a photo of herself getting ready for the Sci Tech Awards last week, several fans began commenting how much younger she looked and even began to wonder if she's had any plastic surgery done.

"Ask anyone who knows me and they'll tell you I love research," Munn captioned the photo. "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."

She went on to explain that the first thing that helped was the fact that she lost 12 pounds while filming "X-Men," and that she has kept the weight off with regular workouts. "The weight loss leaned out my cheeks and jawline," she explained. "Working out is also great for your skin because it increases blood flow to your face which helps rejuvenate."

Her second tip is that she reshaped her eyebrows, which every girl knows can make a huge difference in someone's appearance. Since Munn does her own eyebrows, she decided to stop plucking them with such a high arch after a facialist pointed out that they looked like a frown. Now, she lets the top grow out and instead only plucks the bottom. "That gave my brows a more horizontal angle," she added. "And instantly brightened my eyes."

As you can see in the photo from a year ago, Munn used to have a lot of freckles and sun spots, so the third skin tip she's sharing is that she got rid of them thanks to Proactiv Mark Fading Pads. "Dark spots prevent your skin from reflecting light and gives you dull complexion," she explained. "I wipe my face with one every night and now my face has a more even tone and the large sports aren't as noticeable."

And for her fourth and final tip, Munn, once again, is swearing by potatoes. "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 wrote, telling followers to look up the "Connie Chung Yuzihara" video for more information. "There are Hyaluronic Acid pills and vitamins but I think the best way to get it in your system is by eating them in foods that naturally have them."

Munn doesn't plan to stop there, either, as she's still researching ways to prevent neck wrinkles and promises to let her fans and followers know as soon as she finds out more.

 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.
