Much in the way you wouldn't leave the house without brushing your teeth, these women slather on sunscreen every morning, without fail, even if they're simply en route to the office. And, no, a BB cream with SPF 15 doesn't count.
Even if their day cream and foundation have SPF protection, they still layer on a dedicated sunscreen (We love Dermalogica Pure Light SPF 50, $62 for its quick absorbency and matte finish).
When outdoors for extended periods of time, our perfect-skinned women are just as diligent about reapplication -- every two hours as recommended. One of our favorite ways to reapply without messing up makeup: using a mineral sunscreen powder that we can dust on. Try: Colorescience Sunforgettable SPF 30 Mineral Powder Sun Protection, $50.
Why you should try it: "Every day, rain or shine, it's important to use an SPF 30 sunscreen with broad spectrum protection," says Jaliman. She says there have been twin studies that show that the twin who wore sunscreen looked 10-20 years younger than the twin who did not wear sunscreen.
Jaliman prefers physical sunscreens with a high concentration of zinc oxide, because they're soothing to the skin and don't cause irritation. If you're going to be sweating outside, choose a water-resistant formula that's good for at least 80 minutes.
Many are diligent about adding a layer of antioxidants under their SPF to further prevent free radical damage (a favorite: SkinCeuticals CE Ferulic). Dawn uses them diligently under her sunscreen, even when going for a run (as a New Yorker, she's exposed to a lot of pollution -- read more about the effects of pollution on your skin here).
Why you should try it: Antioxidants combat free-radical damage from cigarette smoke, pollution, UV rays and stress, explains Jaliman. But how, exactly, do free radicals mess with your skin? They damage collagen and elastin tissue, resulting in -- you guessed it -- wrinkles, she says.

The Habit: They're Meticulous About Washing Their Face
While the makeup routines of our interviewees varied, they all have one thing in common: They remove every speck of it every single night.
To wash away every last trace of dirt, pollution and makeup from the day, do as the flawlessly skinned (and Japanese) do, and double cleanse. Carol, 24, always uses an oil cleanser to remove her makeup before washing with her regular cleanser to get her face squeaky-clean and ensure no pore-clogging makeup is left. Bonus points if you use a sonic cleansing brush, like the classic Clarisonic, a product many respondees are fans of.
Why you should try it: Remember those pesky free radicals? If you don't thoroughly wash your face at night, not only are you leaving oil-clogging makeup behind, you're also leaving wrinkle-causing pollution all over your face. In the short term, going to bed without washing your face can lead to breakouts and uneven skin tone; in the long term, it leads to free radical damage (AKA wrinkles and dullness).

The Habit: They Do Their Downward Dogs
You don't need to hit the gym every single day, but you do need to exercise consistently. Our women with perfect skin did all kinds of activities, from going on runs every other day to doing cardio and core strengthening exercises twice a week.
A study at McMaster University in Ontario found that after age 40, men and women who exercised frequently (think: three hours of moderate exercise a week) had skin that was closer to that of 20- and 30-year olds -- even if they were older than 65.
As for post-workout skin care: Dawn uses and acid-based cleanser if she's worked up a sweat with sunscreen on to head off breakouts, while Kristen, a 41-year-old from the Bay Area, always gets her cleansing in within an hour of sweating. Moral of the story? Don't let your sweat sit too long on your face, or say hello to acne.
Why you should try it: Exercise isn't just good for your body and mind. In fact, Jaliman says it is very important to the health of your skin because it increases the blood supply and flow to your skin, bringing it nutrients and making it healthier and glowier. Time to start actually using your Equinox membership.

The Habit: They Don't Drink Diet Coke
The women we interviewed definitely weren't guzzling soft drinks or ordering take-out every night. While they admitted to the occasional indulgence (chocolate and wine were common), for the most part these women noshed on whole foods like fish, veggies, fruits and nuts.
New York-based makeup artist Joey noticed a serious turnaround in her skin after she did a major diet overhaul, and has a smoothie every morning consisting of several leafy greens, flax oil, chia seeds, lemon, blueberries and, occasionally, protein powder. They also skip processed foods, and limit added sugar. A common thread among the women was that they nourished their body with healthy lifestyle choices, which allows them to have low-maintenance skin care routines that complement their lifestyles.
Why you should try it: Turns out, you really are what you eat (We know -- shocking, right?). Fruits and veggies are essential to glowy skin because they are high in radiance-boosting antioxidants called carotenoids. "It has been show that [antioxidants] increase the glow to the skin and improves the color of the skin," says Jaliman -- making you look healthier and younger. She recommends pairing green and orange produce with plenty of healthy fats, like avocado (of which several of our responders eat at least once a day), which increases your body's absorption of carotenoids.
We all know her: The woman who has the kind of amazing, perfect skin (seriously, where are her wrinkles?) that makes you wonder if she's resorted to witchcraft, or just has a really good dermatologist. Turns out, her face is full of secrets -- and we're here to spill them. We chatted with women of all ages who have the glowy skin of our dreams to see what steps keep their skin flawless.
"So many times I say to a patient, 'You have such beautiful skin,' and they'll say, 'Well, my grandmother at age 90 had no wrinkles,'" says Debra Jaliman, MD. "But that doesn't mean if you were dealt a bad hand in the genetics department that you can't overcome it."
Here, the eight steps women with perfect skin always do -- try them and say hello to radiant skin.
