The celebrity made his acting debut as a teenager and once mentioned that, even then, he looked much younger than his actual age. Because of his looks, he has also been mistaken for Justin Timberlake. Besides his appearance, he battled depression during his early years, something that stayed with him as he grew older.

From soap operas to big-screen hits, his life has played out in public. Now in his 50s, he continues to impress with his youthful looks and honesty about mental health, parenting, and life in Hollywood.

That striking appearance, however, had its drawbacks — especially during his early years in the 1990s when he was still trying to find his footing. He once said:
“I moved to New York when I was 17, and I looked like I was 12. So, you know, I wasn’t getting in anywhere. I looked like a literal child when I was a teenager. I was just pretty slow in that regard.”

While his boyish appearance brought challenges in his personal life, it didn’t stop him from making bold choices in front of the camera.

He got his start on the soap opera “One Life to Live” (1968), where he played Billy Douglas, the first gay teen character on daytime television in the U.S. The storyline tackled hard issues, including the fear of coming out and dealing with hateful reactions from others.

After that, he took on more TV roles before moving into film, appearing in “White Squall” (1996), “Nowhere” (1997), “I Know What You Did Last Summer” (1997), and “Cruel Intentions” (1999). As his film career picked up speed, his personal life also changed — he married his “Cruel Intentions” co-star Reese Witherspoon in 1999, and they welcomed their first child later that year.

A few years later, the television star and the film producer expanded their family with the birth of their son, becoming a family of four.

The veteran actor later appeared in “Crash” (2005), “Flags of Our Fathers” (2006), and “Stop-Loss” (2008). After nine years, their marriage came to an end in 2008.

After their separation became public, media attention quickly turned his life upside down. At the height of the LA paparazzi craze, he found himself constantly followed. Hoping to escape the spotlight, he left the country to find some peace.

But quiet didn’t follow him. As soon as he arrived, strangers came up to him and asked, “‘Excuse me, are you Justin Timberlake?'” the celebrity recalled in an interview once.

Despite the constant attention, his focus remained on his family. Speaking about life after the split, he once said that co-parenting, especially around the holidays, can be delicate.

Still, the star and Witherspoon, who once said he looked much better than Timberlake, ensured they stayed on the same page for the sake of their children.

Even after parting ways, they found a rhythm that worked for their family. During one event in New York City, he explained how they manage Thanksgiving.

“As a divorced dad we trade off, so last year my kids and I went to my parents in Delaware, this year they will be with their mom and I am shooting a movie up in Toronto,” he shared. “I am going to fly down to Philly and just have a Thanksgiving with my parents and the kids get to be with Reese.”

The Delaware native described their approach to parenting with care, noting that divorced parents, like any parent, must learn not to put themselves first.

He emphasized the importance of letting the children have their own experience, rather than focusing on personal time, and shared that he and his former wife had managed that well.

The father of two also acknowledged that the Academy Award-winning actress maintained a healthy attitude toward how they handled things.

While their co-parenting arrangement remained steady, the actor behind it all, Ryan Phillippe, quietly faced battles that were far more personal. He once opened up about his longtime struggle:
“You know, depression has been a huge obstacle for me ever since I was a child. As you get older I think it decreases some, but I’m just innately kind of a sad person. I’m empathetic, and I take on the feelings of others and transpose myself into the position of others.”

Phillippe explained that humor, especially the dark kind, had always been part of him. He believed he was much funnier than people realized, pointing out that his humor leaned toward gallows humor. According to him, those who carry sadness or depression often develop a darker sense of humor.

The movie star noted that many of the greatest comedians he knew shared this trait — they were often depressed and carried a darkness within, yet had a unique ability to make others laugh, which also served as a form of healing for themselves.

That mix of honesty and humor has stayed with him throughout his career, even as time continues to move forward. Now more than 30 years into show business, Phillippe continues to work steadily.

When he turned 47, he joked about how his appearance hadn’t changed much, but he no longer felt like the fresh face he once was:
“I still think of myself as relatively young and I still look relatively young but I am not, clearly.”

Even as he continues working and embracing the passage of time with humor, his youthful appearance brings its own set of complications. Phillippe once pointed out in a separate interview that looking much younger than his age isn’t always a perk. “I still get carded,” he said in his 40s.

His youthful appearance has led to awkward moments, especially when he’s with his daughter, who was 15 then. Strangers have confused him for her older brother, a mix-up that makes her uncomfortable. “It creeps her out,” he admitted, noting that some of her friends have even teased her about including him in games like spin the bottle during their sleepovers.

The confusion around his age may bring laughs or awkward moments, but staying youthful isn’t something he leaves to chance. The “Shooter” star credits his lasting looks to family genes and consistent effort.

He once said his mother also “still looks young,” and explained that taking care of his body helps more than just his appearance. Phillippe believes that a healthy lifestyle can ease the challenges of getting older.

“If you eat right and exercise, it makes aging that much less disturbing, depressing and difficult,” he noted. Along with staying active and eating well, he relies on meditation to manage long-standing mood issues. And when it comes to looking after his skin, he never misses a step.

Sticking to his wellness habits clearly pays off, as his appearance continues to draw attention even at 50. In one Instagram post, Phillippe shared a mirror selfie that quickly caught the eye of his followers.
In the photo, the Hollywood star took a mirror selfie wearing a sleeveless white shirt, highlighting his toned arms and tattooed left arm. He pairs the look with sunglasses, bracelets, and a crossbody strap. His hair is tousled, and earbuds hang from his ears, giving off a relaxed, youthful vibe.
