The fountain of youth may not be an actual, physical thing, but that hasn't stopped anyone from trying to chase it — stars included. Although there is also nothing wrong with embracing your age, celebrating your wrinkles, and letting your hair turn a glorious shade of gray. Whether you want to try every new serum and treatment to turn back the hands of time, let yourself age naturally, or do something in the middle of those extremes, it is your choice to decide how you want to age.

Celebrities also fall in the range of these extremes with their anti-aging treatments. While some celebrities stay tight-lipped with the skincare routines and treatments that get them glowing, these 16 stars hold no reservations about letting us in on exactly what they do.

From #lifehacks to product recommendations, keep reading for the stars' best anti-aging advice.

Jennifer Lopez

Everyone in the world is after the multi-hyphenate's skincare routine because, well, have you seen that J.Lo glow? This is why she founded her skincare brand: JLo Beauty.

She previously told us that her secret is less is more. Well, that and olive oil. "My mom and aunts swear by olive oil to deliver a glow," she told us. "The hero ingredient in JLo Beauty is a modernized version of olive oil, called the Olive Complex. It's a combination of ingredients derived from extra-virgin olive oil, fermented oil, leaf extract, and squalane. It gives the skin this weightless, all-day hydration, antioxidant protection, and an ageless radiance. And it doesn't smell like salad dressing," she added with a laugh.

John Legend

The EGOT-winning musician steals a lot of his beauty secrets — and products — from his wife Chrissy Teigen. "We love SK-II — the moisturizer, the Pitera [Essence]," he previously told InStyle. "I think in general, that's probably a common story for couples, [especially hetero] couples; a lot of times the guy is getting tips from their girlfriend or their wife, and we're influenced heavily by their choices."

Lily Aldridge

The model told us that her secret to her flawless complexion is moisturizer and sheet masks. "Say I'm heading out for a date night: I start by moisturizing to prep my skin — sometimes I'll even throw on a face mask," she previously told InStyle, adding that the sheet masks aren't just for your face. "Toward the end of my third trimester with my son, when I was counting the seconds until giving birth, I'd put one sheet mask on my face and another on my bump and watch TV. My daughter thought it was so hilarious!"

Kelly Ripa

You may be wondering how the heck the morning talk show host stays so youthful and energetic. Her secret? "I feel like dancing keeps your mind and body young," Ripa, whose workouts are mostly dance-based, previously told InStyle. "I have to remind myself that I'm not 23 because I still feel like I am," she adds.

Penelope Cruz

According to Cruz, the best beauty advice she ever got came from her mother. "[She always said] to eat healthy and get a solid amount of rest. I remember her sounding like a broken record telling us to eat our veggies and go to sleep," she previously told InStyle. "She annoyed me, but now, as a mother, I hear myself saying the same things."

Jennifer Aniston

The reason Aniston hasn't aged a day since her time as Rachel Green? A healthy mixture of microcurrent facials, which she dubs "a little workout for your face," and the Clear and Brilliant Laser treatments. "It's a great refresher, and there's very little downtime," she told InStyle. "It won't make you look like a peeled tomato."

Additionally, she uses a light hand when applying makeup, and swears by Aveeno's SPF 60.

Halle Berry

For Halle Berry, the dewier her complexion, the better. "No matter what age you are, you always look a little better when your skin is a little dewy, not too powdery. I went through phases where all I wanted to do was be matte and powdered up, but then I found it wasn't the best look for me," she told InStyle. "Before I do my makeup, I spray my face with rosewater and let that sink in. It keeps my makeup looking very dewy, and I feel like it just makes me look more youthful, alive, and fresh."

Salma Hayek

Hayek's formula for perfect skin involves never going to bed with a full face on. "I've never gone to bed without washing my face. Never in my life," she told InStyle. "Even if I'm sick, tired — heck, even if I was drunk! I might forget to take off the dress, the shoes, and the jewelry, but not the makeup. It's second nature."

Sarah Jessica Parker

Parker, too, is an advocate for always going to bed with clean skin. "The thing I'm most diligent about is washing my face," she told InStyle. "I say to my husband, 'Oh, I'm so tired, Matthew! I don't want to wash my face.' He's like, 'Why do you need to?' He doesn't get it. I also always wear moisturizer and lip balm."

Chrissy Teigen

Teigen loves Shani Darden's Retinol Reform Resurface serum. "My aesthetician makes this product," Teigen told InStyle. "It smooths out fine lines. Every time I use it, I get compliments on my skin the next morning."

Olivia Wilde

Olivia Wilde swears by the True Botanicals Renew lineup. "My regimen is the Pre-Cleanse Oil, followed by the Hydrating Renew Cleanser," she tells InStyle. "I use the Vitamin C Booster a couple times a week, and I love the Nutrient Mist, but the Pure Radiance Oil was my gateway into the line. I slather it all over morning and night."

Jessica Alba

"My mother taught me to always wear sunscreen, and to treat my beauty products as an investment," she told InStyle. "She would cheap out on her clothes before she would ever skimp on her skincare or makeup. She'd say, 'Listen, this is your face. It's all you've got.'"

Linda Evangelista

The supermodel is a fan of the Erasa EXP-30 serum. "I've tried everything, from drugstore to high-end, but I really started to notice a difference after using this," she told InStyle. "My pores got smaller, and my skin tone evened out."
