Helen Mirren uses this serum before every red carpet — it's $18, nearly 50% off

Dame Helen Mirren is definitely one of our personal icons. A superstar for over six decades, she's one of the most celebrated actresses in history — read: one Oscar, four Emmys and four BAFTAs — but on top of that, the 78-year-old combines her onscreen virtuosity with a cheeky, irreverent wit and timeless beauty. We're also obsessed with the skin-care tips she's given over the years. Whether for promoting the healthiness of hair, skin and nails or a cream that promises to bestow a lovely rosy glow, La Mirren is always up for turning us on to ace, affordable beauty products. The latest entry in that pantheon? L’Oréal Paris Revitalift 1.5% Pure Hyaluronic Acid Serum, her trusted pre-red carpet must-have and a product that, according to the brand, is the number-one selling serum in America. Best of all, this skin-loving salve is now nearly 50% off at $19, all the way down from its original price of $35.

Why is it a good deal? 💰

A-lister-approved skincare at a drugstore price? We love to see it! Along with Dame Helen, thousands of perfect reviews from customers confirm that not only is this serum a great product, but its Amazon price nearly as low as it goes. "This stuff did wonders for my skin," one reviewer said. "Absolutely always keep coming back to buy again. And it's cheaper than the store." Right now, you can grab a bottle for yourself for just $18, down from $35 — a near-50% markdown.

Why do I need this? 🤔

So how does Mirren herself utilize this hydrating little wonder? In a recent Cannes tell-all with The Telegraph, she said that while "I don't really have any [pre-red carpet] rituals per se, as I really trust the team to make sure I'm looking and feeling great ahead of the carpet," she does do one thing before her makeup artists get to work: She preps and moisturizes her skin using L’Oréal Paris Revitalift 1.5% Hyaluronic Acid Serum.

This top-rated bestseller is backed by dermatologists too. “[It] was clinically tested for both stability and effectiveness,” NYC dermatologist Joshua Zeichner tells Yahoo Lifestyle. He served on the external advisory panel of docs who had access to the development and research of the serum and validated L’Oréal’s claims.

What makes L’Oréal Paris Revitalift 1.5% Hyaluronic Acid serum such a skin-care standout? Its main ingredient. “Hyaluronic acid is a humectant ingredient that pulls in hydration to the skin to plump and moisturize,” explains Zeichner. “It acts like a sponge and can bind to 1,000 times its weight in water.” Zeichner calls the hydrating active ingredient the “ultimate multitasker in skincare,” adding that improved hydration results in the minimized appearance of fine lines and a boost of radiance. All it takes is a few drops in the morning and night, he says.

The best part is that the serum is suitable for all skin types. “It can be used across all skin types, even in those with sensitive skin,” he says, adding that those with dry or dull skin will reap those hydrating benefits as well.

What reviewers say 💬

This luxe liquid isn't just for big names — Amazon reviewers are big fans too, with over 33,000 five-star reviewers rave about the formula.

Pros 👍

“I feel I look five years younger,” one chimed in. “My complexion is incredible. Can't imagine going without this product ever again.”

“When I first started dating my boyfriend, he asked me, ‘What happened under your eye? Did you have an injury as a kid?’ NOPE. That was just a deep wrinkle,” a shopper recalled. “So I figured I needed to do something about it and thought I would try this. With just ONE use, the deep wrinkle under the eye was already significantly less visible. I am in love with this product. I've only been using it for a few days, but I can already see the difference in my appearance and the lines under and around my eyes. I highly recommend it to anyone!”

“It didn’t take long to tell this stuff works! I noticed changes in my skin texture after one use, and now it’s been about 10 days, and my skin is so smooth, soft, and even-toned,” another reviewer dished. “Can’t believe it. I don’t even feel the need to wear foundation.”

Cons 👎

FYI: This also includes retinol, which is not for everyone. "If you're sensitive to that, I'd recommend you move on to something else," a shopper advised.
