For years, Pharrell Williams has defied time with his youthful appearance. His smooth, glowing skin has sparked entire internet discussions about how he just doesn’t age. The rapper, producer, musician and designer, who is now 51, has kept his little secret until now.

But we’ll find out. After Williams dropped Humanrace, his skincare line, in 2020, fans finally felt like he shared the key to the fountain of youth. But even after that, social media was still abuzz with comments praising and questioning the secret to his youthful glow.

“It’s not like we as a society should start asking Pharrell some questions. 48 years old??? It’s time to investigate,” said another user on X.

Some even joked that even though it’s still his birthday, he doesn’t age regardless of the passage of time.

“Happy birthday @Pharrell! He’s turning 47 but still looks 25,” Essence tweeted in 2020.

For years, people could only guess about his fountain of youth, but the rapper and fashion icon finally revealed how he maintains his ageless look. The secret comes down to something surprisingly simple: exfoliation.

Williams swears by regularly exfoliating his skin to remove dead skin cells, according to an interview with People magazine.

He has a more extensive routine that he says you can find online, but it also lets your inner child shine.

“It’s literally right here. That inner child, never silence it. Don’t ever (go): ‘Oh, I can’t do this anymore.’ No. That’s why you absolutely have to do it now,” he said. The people who want to put you in a box? They tried that with me too, and here we are.”
