We all know we feel better with a little sun, but what if you could replicate that healthy glow year-round? According to NewBeauty readers (and a bunch of celebrities), Clarins Double Serum ($140) is the secret to radiant, flawless skin.
In a recent survey of more than 400 NewBeauty readers,* we asked them to name their holy-grail skin-care product. One reader didn’t hesitate: “It’s been a staple in my routine forever,” she shared of the Clarins Double Serum. “It makes me feel like I’m using a self-tanner and just keeps my skin looking flawless.”
That radiant, just-back-from-vacation glow is exactly what fans love about Clarins Double Serum, including Brooks Nader, who called it “the best” and praised the luminous finish. Even Kourtney Kardashian is a fan, famously using it from head to toe. “You know that I’m obsessed with this Double Serum,” she said in a video. “I know it’s a treat but my body deserves it.”

Launched 36 years ago, the formula itself is a powerhouse. It’s a dual-phase serum inspired by skin’s natural water and oil balance, designed to target both chronological aging and environmental stressors. With ingredients like turmeric, organic harungana extract and peptides, it works to visibly firm, smooth and plump the skin while boosting radiance and minimizing pores. The only thing better? Proven results.
In clinical studies, users saw results in as little as seven days—including improved texture, reduced wrinkles and a stronger moisture barrier. And with just one drop, it’s easy to see why this serum has earned its cult status.
