I've Interviewed 40+ Beauty Experts—They've Influenced Me to Buy These 30 Gems

Paris Hilton says this lightweight essence gives her a flawless "IRL filter" effect. Consider me sold.

"Lancôme's Juicy Tubes are everything," Hilton says of the nostalgic lip gloss. "I've been obsessed since the 2000s. They're super glossy, smell delicious, and give that perfect Y2K vibe that's totally iconic and still so hot today."

Hilton reaches for this multitasking face mask to get glammed up for the red carpet and to wind down for the night. "It always makes me feel like I just stepped out of my Sliving Spa," she tells me. "I even had it custom bedazzled in pink crystals, of course." Okay, I'm jealous!

I'm a sucker for a rich, glow-giving moisturizer, and this one is the crème de la crème, according to Hilton.

If there's one product that's been name-dropped more than any other on this series, it's the Summer Fridays Lip Balm. It's a favorite for a reason—the formula is simply unmatched.

"This is one of the quickest pick-me-ups on mornings when I need something fast and effective that makes me feel pulled together," Lauren Ireland says of this brow gel.

Looking for that effortless sun-kissed glow? This ultra-buttery cream blush is your answer. Ireland loves Soft Strawberry for a sheer wash of pink, and Hewitt uses Toasted Terracotta as a bronzer-blush hybrid. Pro tip: Use it with the Blush Brush ($28) for a seamless application.

Hewitt uses this jelly serum stick to instantly cool, refresh, and soothe her skin.

"I've tried so many LED masks, but this one is by far the best," Chriselle Lim says. "It's clinical grade, super powerful, and you only need three minutes a day to see results."

I'm not kidding when I say everyone I know is obsessed with this fragrance. Lim says it's the perfect day-to-night fragrance and layers beautifully with other scents.

I already love this lip liner, but if you're on the fence, take it from Lim: "It glides on like butter, feels hydrating, and pairs perfectly with lip tints or even just by itself," she says. "I've been using the shade Bend, and it's just chef's kiss!"

Lim calls this serum "Botox in a bottle." Enough said.

Overwhelmed with all the skincare tools out there? Honestly, same. Lim says this tool not only fits seamlessly into her busy routine but also makes her skin smooth and glowy with minimal effort.

Dermatologist Muneeb Shah, DO, says this potent blend of retinaldehyde, argireline, matrixyl, glycolic acid, lactic acid, and antioxidants is "like a fountain of youth." He suggests using it nightly to address all your major skin concerns.

This salicylic acid exfoliant is viral for a reason, according to Shah.

Using the same face towel or pillowcase is a common cause of acne, and Shah says using compostable cloths can make a huge difference in your routine if you're acne-prone (like me).

Mineral protection? Check. Dewy finish? Check. Dermatologist approved? Check.

"There's good data to show that bad water quality (high calcium), can cause the surfactants in your cleanser to become more harsh and irritating," Shah explains. "A water filter can make a huge difference to remove impurities that can damage the hair and skin."

"If I were to choose any one of my products to splurge on, this would be it," Rita Hazan tells me. "It's so hydrating and perfect for all hair types—but especially color-treated, dry, or damaged hair." (Ahem, me.)

This editor-loved fragrance is also Hazan's signature scent. It's an enchanting spicy floral scent with notes of tuberose, bergamot, and white musk.

We all have those pricey-but-worth-it products, and this is one of Hazan's. "La Mer has many types of face creams, but the original Moisturizing Cream is my go-to," she says. "My skin always feels firmer and looks healthier with consistent use of this cream.”

According to Hazan, this iconic bronzer is the perfect color: not too light and not too dark.

This famous lip plumper has sold out 12 times, and after seeing the before-and-afters, I understand why. "I designed this product to mimic the hydrating look of a syringe of filler," Lara Devgan, MD, says. "It's powered by mixed molecular weight hyaluronic acid, niacin, and ceramides." She suggests taking a before-and-after pic to see the results—just wait five minutes for the full effect.

"Discovering Santal 33 was a revelation," Devgan says, also noting that the sophisticated fragrance has become her olfactory signature.

Devgan loves this "liquid gold" body oil that's made with sustainably sourced ingredients.

If you want long, luscious lashes the natural way, reach for this celeb-loved eyelash serum.

The secret to Miranda Kerr's radiant skin? Noni oil, aka liquid gold. She applies a few drops every day for a hydrated, dewy glow.

"This blush gives the most natural flush," Kerr says. "It melts into the skin and gives that healthy, just-pinched glow."

We all need our beauty sleep, and Kerr has influenced me to add a silk eye mask to my nighttime routine. "The pure silk feels so luxurious and gentle on my skin, and it really helps block out light so I can fully unwind," she says. "It's the ultimate little luxury for better sleep and waking up refreshed."

Kerr knows all the best clean-beauty recs, and this lengthening mascara is one of her tops. Psst: It's also easy to remove, which we love.
