Joel Kim Booster, who told us he has acne-prone combination skin, says this ended his search for a nondrying everyday cleanser. “It’s easy enough that I can use it multiple times a day without worrying about stripping my skin. It is a great all-purpose sort of cleanser for me,” he says. “I’ve been sort of searching for a good cleanser for the better part of the last decade, and this one is the best one that I’ve found.”

Two celebrities — Naomi Watts and Imaan Hammam — have said how moisturizing this Eucerin lotion is. Watts says it’s the one thing that’s helped her badly cracked feet, while Hammam uses it to soothe her scaly winter legs.

On the hair front, Laila Gohar told us she’s been using Olaplex’s No. 3 Hair Perfector for nearly a decade after a hairstylist introduced her to it. “Now I always keep one of those little bottles around,” she says. “It makes your hair smoother and softer. It looks healthier and less split-end-y.”

“I’ve been using this since I was 13 years old. My mother and my sister also use it,” Christina Ricci told us about this leave-in conditioner. She says it helps her combination straight and curly hair hold her desired shape and keeps her hair healthy.

And if you were ever wondering what Smokey Robinson’s signature scent was, it’s Calvin Klein Obsession. “I very seldom have used anything else. Oh, how do you describe a smell, honey? I have no idea. It just smells good on me, I hope,” the singer said.

Celebs weren’t immune to the Stanley hype. Paige DeSorbo, Campbell “Pookie” Puckett, Hannah Brown, and Nicola Peltz Beckham all included the water bottle on their lists of things they can’t live without. “It’s so funny — it’s such a basic-girl thing, but they’re great and fit in the cupholder,” says Brown. “I love being able to hold the handle. What’s not to love? There’s a reason everybody’s obsessed with them.”

Hydro Flask is another big hit, with Noah Beck counting himself as a fan. Right now, his is deeply discounted and just over $30.

And the humble Nalgene is also on sale. John Schaefer, who was at first skeptical about it, bought one for his daughter and quickly became a convert. “I was like, Oh, come on, $15 for a plastic bottle? Well, that is the same bottle I’m still drinking out of 16 years later,” he says. “These things are indestructible.”

It’s no surprise celebrities are as obsessed with the classic Levi’s 501s as we are. Most recently, Brianne Howey told us these are her everyday go-tos, since they’re “incredibly comfortable, flattering. It’s a good classic straight fit, and I love the slight stretch.” And back in 2019, Karen Walker said they’re the denim that lasts her a decade. “Every six months, I buy a pair of sneakers, but every ten years, I buy a pair of 501s.”

And Zooey Deschanel told us her preference is dark-wash straight-leg jeans. “There’s just not any better jeans than Levi’s … They’re not overpriced, they’re just good jeans, and I like that,” she says.

Self-described Calvin man Marlon Wayans told us these classic cotton tees are on his rider. “I perform in these T-shirts because they’re soft without being too soft, formfitting yet loose, and durable — and they soak up sweat so I’m not looking crazy onstage,” he says. “They’re perfect. I wear them on tour, at the gym, and as an undershirt.”

Joanna Goddard turned us onto these brieflike, flattering pairs of underwear. They’re a “really good fit,” she says. “I got a bunch in black, but there are also three different shades of blue in a package or three different shades of pink, so I got a couple of those too.”

Tim Heidecker and Wayans’s briefs of choice are these Calvin Kleins. “They fit well and keep me and my fellas cool. It’s nice, clean cotton,” says Wayans. And Heidecker says they’re the only pair he packs on tour or while traveling.

According to Ego Nwodim, multiple Saturday Night Live cast members use this to stave off colds during the winter months. (Just be sure to buy the tablets and not the capsules, Nwodim says.) “It’s incredibly effective … I have them in my dressing room. I have them at our pretape studio. I have them in my apartment. I have them in my house. I have them in my purse in a little pill case. I have them everywhere.”

If you have also picked up on doing morning pages recently (à la Julia Cameron’s The Artist’s Way), consider Chace Crawford’s notebook of choice. The classic lined Moleskine is a deep 33 percent off, bringing its price down to just $14.
