The ageless star also tells the glossy that she surprisingly still has some of the clothes she rocked on Friends days in her closet, even though it's been two decades since she first hopped onto the scene as the beloved Rachel Green in the popular '90s comedy series.
"I have certain things I have yet to throw away from my days on Friends," she reveals. "My red squared-toe loafers might actually be making a comeback, that's awesome. See, it's coming back -- I knew it. I also have those nice high-waisted jeans. I'm so glad I didn't throw any of those out. I loved the '90s."
While she was a big fan of that decade, she has much different feelings about the '80s. When asked what she regrets most from that time period, her answer was quite hilarious: "The entire decade!"
"There was a period where I cut my hair really, really short," she recalls. "It was long on top, short on the sides. I think right above the ears -- about an inch above -- I shaved my head, and that was kind of a really bad look. It was like a faux kind of chicken sh*t Mohawk."
"Sometimes you learn the hard way," she adds. "The amount of makeup I piled onto my skin and the wonderful hair colors and cuts that my hair went through -- I don't look back fondly on some of those choices. But I do laugh at them!"
Over the years, Aniston's discovered that everything just gets "simpler."
"Less is more, less makeup, less fuss, and just more natural, which I kind of prefer," she says. "My skin-care treatment is very simple. I've found that anytime I try to do some kind of fancy hair or makeup routine or skin-care routine, it gets more complicated."
So, what products does she credit for her smooth, glowing skin?
"We need to be really good and mindful of what we eat and how we take care of our skin," she advises. "Getting a good night's sleep is extremely important, as is hydrating with water, water, water. It's so important to getting that extra glow."
It makes total sense that she swears by these products. She is the face of the brand, after all!
And it looks like her husband, Justin Theroux, is just as fascinated with Aniston's beauty as the rest of us are, judging from the gorgeous snap he posted of his breathtaking girl gazing out of a window in Paris in February.
