Pharrell Williams appears to have barely aged since he first broke through in the early 1990s. His ageless looks are so renowned they’ve become a meme on social media.

Now the 44-year-old artist has revealed how he does it in an interview with Dazed magazine & the answer rather pedestrian: Exfoliation & hydration.

Pharrell explained has an extensive exfoliation regime & compared the routine that of a “narcissistic madman”.

He said: “I exfoliate like a madman. When you exfoliate & 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.”

The Happy songwriter did also reveal more of his skincare secrets in an interview four years ago & how he’s taken cues from supermodel Naomi Campbell.

He said: “My dermatologist, Dr. Elena Jones, gave me the Glytone Self-Foaming Cleanser, which I wash off with cold water to close my pores. I follow that with a Clearing Toner & Moisturizer, also from my dermatologist.

“You have to take care of your skin. Years & years & years ago, Naomi Campbell pulled me aside & said, ‘Listen, this is what you have to do—you have to go to a dermatologist; you can’t keep using drugstore products.’ Well, you can, but with the store products you have to be really diligent.”

So the secret to not aging for almost three decades is hydrating & exfoliating as well as having a dermatologist & prescribed specialist products.
