No one can deny that at 44, Pharrell Williams looks so much younger than his age.

People noted that the "Happy" singer looks younger than most of his contemporaries. In a recent interview, the singer revealed what helps him look young.

"I exfoliate like a madman," Williams told Dazed. "When you exfoliate and you drink a lot of water, that does good for you. To me, the key is just exfoliating, like a monster. There's a lot of dead skin. All the time. Like a narcissistic madman."

When it comes to fashion, Williams believes that it is an "indicative of who you are and what you're feeling." The singer dresses up according to how he feels, where he is going or on the weather. For him, fashion and style are the same. "When people are like, 'I don't really have any style, I don't dress up,' you kind of are. That's what your clothes are saying."

Aside from exfoliating, Williams also practices gratitude. For him, one has to learn to appreciate every little thing that comes his way. "All of the variables that are in your life, they don't have to be there. You've gotta give things to something bigger than you," the "Freedom" singer explained.
