BO DEREK, 57
If ever there was a perfect 10, it was the blonde-haired, blue-eyed 23-year-old who captured moviegoers' attention cavorting in a swimsuit and cornrows (and sparking a global hair trend!) in the 1979 Dudley Moore rom-com, 10. In June 2014, the now 57-year-old attended the Taormina Film Fest with longtime love, John Corbett (Parenthood), and she looked as fresh-faced as ever. But aging doesn't worry her. "I look at my [facial] lines," she told Hello! magazine in 2008, "and I think, 'Well, shoot! They're marks of a lot of fun.'"

ASHLEY JUDD, 45
A year after splitting from race-car driver husband Dario Franchitti, the actress proves she wears the single life well. Though she plays a selfless mom in Divergent, Judd is more the glamorous, plunging-neckline type at the movie's March 18, 2014, L.A. premiere. More than a decade after starring in successful films like Double Jeopardy, Divine Secrets of the Ya-Ya Sisterhood and De-Lovely, this beauty is de-lovlier than ever. In 2012 she slammed critics who speculated that her "puffy face" was the result of plastic surgery – a claim she sharply denied in a Daily Beast essay. "I ask especially how we can leverage strong female-to-female alliances to confront and change that there is no winning here as women. It doesn't actually matter if we are aging naturally, or resorting to surgical assistance. We experience brutal criticism," she wrote.

ELIZABETH HURLEY, 48
Did someone just turn back the clock to 1997? Because Hurley's brunette waves and blue eyes are as striking as ever in October 2013, more than 15 years since she became a household name thanks to her tumultuous relationship with Hugh Grant and sexy siren roles in Austin Powers: International Man of Mystery and Bedazzled. In the nearly two decades since, Hurley welcomed son Damian in 2002 and got engaged to Australian cricketer Shane Wane in 2011, but her newfound family life hasn't kept her from maintaing her sultry self-image, which she played up during her salacious Gossip Girl guest stint on the show's fifth season.

GINA GERSHON, 51
"There's always someone younger and hungrier coming down the stairs after you," Gershon's predatory stripper Cristal Connors famously said in 1995's Showgirls. But we doubt anyone can take her place – nearly 20 years later, the actress looks as sexy as ever. She's continually been on the radar, having popped up on TV series like HBO's How to Make It in America, but it looks like Gershon (pictured at right in October 2013) is poised to truly take the spotlight once again. With her recent TV movie House of Versace in which she played the legendary Donatella, and stylish cameos at fashion shows and celebrity weddings, all eyes are on Gershon – and her fabulous figure.

KERI RUSSELL, 37
Going from curly to straight is the only noticeable difference in the former Felicity star, who in 1998 made waves as the show's titular curly-haired ingenue. When the series wrapped four seasons later, Russell appeared in movies such as 2007's Waitress, before making a return to TV in 2013, earning praise as a spy-next-door undercover KGB agent in The Americans. As for keeping her Felicity-era glow, the mom of two, seen at right at the August 2013 premiere of her film Austenland, credits a nerdy workout video she does in her closet, plus a healthy attitude. "I'm not a complainer about age. I think my girlfriends all look so much better now than they did 15 years ago," she tells Women’s Health.

DAISY FUENTES, 46
Has she found the "fuente" of youth? The always fashionable former MTV veejay (seen left in 1994 and right in 2013) was omnipresent during the channel’s heyday, from hosting House of Style to releasing her own fitness video. Credit her unchanging beauty to the power of positivity: Fuentes, who currently hosts the Telemundo singing competiton La Voz Kids, says part of her routine is to "end the day on a really positive note. As I wash everything off I try to wash everything out of my mind as well. It really helps, you get a relaxing, restful sleep and you’re in a positive frame [of] mind."

ANDIE MACDOWELL, 55
The former L'Oréal Paris model found success in a decade-long string of '90s movies, including Green Card, Groundhog Day and Four Weddings and a Funeral. Still rocking the same stunning looks, slim figure and lush locks, MacDowell (seen at right in July 2013) now stars on the Hallmark Channel drama Cedar Cove. The model mama credits her agelessness to staying stress-free. "And even if I am really worried about something, I can go to a yoga class and release it," she tells PEOPLE. "So I feel the most gorgeous after I've taken a yoga class or after riding horses."

MINNIE DRIVER, 43
She may have played an ugly duckling in her big-screen debut as Benny in 1995's Circle of Friends, but Driver keeps getting more lovely every year. Since cementing her movie-star status with an Oscar nomination for 1997's Good Will Hunting (and famously dating costar Matt Damon), she's been a continual force on the red carpet. With the release of her August 2013 film I Give It a Year (seen at right at the premiere), dare we say the British beauty looks better than ever.

BROOKE SHIELDS, 48
The hair's a little straighter and she's got a few laugh lines, but Shields hasn't lost any of the wholesome gorgeousness she possessed in 1982 (left), when she was a teen superstar thanks to films like The Blue Lagoon and Endless Love. Now playing a middle-aged mom in the June 2013 comedy The Hot Flashes, Shields keeps things simple, beauty-wise: "Clean, tone, keep yourself moisturized," she tells Health magazine. "The rest is internal: Protect yourself from the sun and drink water." Good genes (and good jeans – remember her controversial 1981 Calvin Klein ads?) undoubtedly also help.

DARYL HANNAH, 52
In 1984, Hannah brought her blue-eyed blonde beauty to the big screen as a naive mermaid opposite Tom Hanks in the comedy Splash; more hits followed and by 1987 (left) she was a bona fide star. More than 25 years later, the actress and environmental activist, who stars with Brooke Shields in June 2013's The Hot Flashes, has retained her beach-beauty looks in part by reading labels and avoiding anything containing possible carcinogens: "I use a pure cacao (raw chocolate) oil on my body and hair, and [an] olive-oil-based salve on my face, plus a vegan biodegradable soap," she explains. And, let's assume, she still relies on lots of water.

WINONA RYDER, 41
How does she do it? The actress (seen far left in 1989) still has the same youthful looks that made her a Gen X darling in movies like Heathers and Beetlejuice. According to her makeup artist Kim Collea, all it takes is a trip to the grocery store. "It sounds boring, but the girl eats a lot of salads," Collea says of Ryder, who is back on the big screen in the May 2013 film The Iceman. "And you know those giant Big Gulps cups that most people fill with soda? She’s got hers filled with water."

HEATHER GRAHAM, 43
The hot blonde was just 21 when she starred opposite John Travolta in 1991's Shout and has hardly aged a day since. Her Dorian Gray secret? "I try to get 11 or 12 hours of sleep a night," says Graham, pictured at right at the April 2013 At Any Price L.A. premiere. "It sounds excessive but that's really what I need. It does the trick."

GABRIELLE UNION, 40
Getting older? Bring it on – especially when you look as fresh-faced as Union, who hasn't lost a bit of her youthful glow since 1998. The actress, named one of PEOPLE's 2013 World's Most Beautiful, credits her age-resistant appearance to drinking a gallon of water a day and going without makeup. Her other secret? "I stay young by dating younger!"
14 of 17
CARMEN ELECTRA, 41
Her hair and dress may be different, but Electra, seen right in May 2013, looks virtually unchanged since 1997, thanks to a disciplined regimen of moisturizing and removing her makeup at night. It also doesn't hurt that life's been good to her: "When you're happy," she says, "it shows through your eyes and brightens up everything."

JENNY MCCARTHY, 40
Just 21 when Playboy named her 1994's Playmate of the Year, McCarthy bared all again in 2012 to mark her 40th birthday. That takes guts and an amazing body, which McCarthy (pictured at right in April 2013) has in spades. But the host of The View also lives as purely as possible, she told Shape, and sticks to a diet full of fish, egg whites, fruits and vegetables. She also credits "Botox, working out and spray tanning" as part of her beauty regimen. Clearly, it's working!

GARCELLE BEAUVAIS, 46
It was impossible not to notice the Haitian-born Beauvais's exceptional looks when she worked the small screen on '90s shows like The Jamie Foxx Show and NYPD Blue. A decade later, the White House Down actress (pictured at right in April 2013) still has the natural beauty of a woman half her age. Her biggest beauty tip can be summed up in one word: "Moisturize!"

ALYSSA MILANO, 40
Someone's found the Fountain of Youth! The petite brunette (seen far left in 1989 and at right in February 2013) and new mom still has the youthful exuberance and dewy skin that marked her TV years as a costar of the long-running sitcom Who's the Boss? She shows off her still-amazing looks on the new ABC series Mistresses.
