The 10 Beauty Products Our Readers Couldn’t Stop Buying in 2019

When we tested the Revlon One-Step Volumizer, we couldn't get enough — and now, our readers can't either. Thanks to a smart, easy-to-use design, it combines the power of a hair dryer and the ease of a round brush in one simple step to cut your hair drying time in half (seriously). It has nearly 17,000 reviews on Amazon and right now, it's 35% off and will arrive before the holidays.

All throughout 2019, readers couldn't get enough of the best eye cream our Beauty Lab has tested. It's a star in pretty much every arena: The formula increases skin firmness and hydration by nearly 20%, reduces wrinkles by 10%, fades dark circles, and depuffs eyes. 

For the pearliest whites, readers stocked up on the best teeth whitening strips on the market. After 20 days of use, our Beauty Lab scientists found that these strips whitened teeth two to four shades — in just three weeks' time. Right now, they're 34% off, plus and additional $10 off that. All the more reason to smile.

This Amazon reviewer-favorite is also our readers' pick for the best self tanner of 2019. With over 5,000 reviews and an average 4.3 star rating, reviewers love that it doesn't have that telltale self-tanner-smell, and that the thicker consistency makes for more even application and natural-looking results. "I have been using this product since the summer and it made me seamlessly retain that glowing look — no one noticed a difference," one person said. 

Yes, $400 is a lot to fork over for a hair dryer, but our Beauty Lab (and readers) say it's worth it for the best hair dryer on the market. In our tests, the Dyson Supersonic proved to have the fastest drying speed, strongest airflow, and the highest consumer satisfaction of any hair dryer we tested. "It got hair smoother, and in less time, than any hair dryer I've used," said one tester.

Year-round, readers couldn't get enough of this best natural sunscreen (yay!). With a powerful SPF 50, not only does it prevent sunburns, but it leaves a silky finish for a great base beneath makeup. "My skin looks really great, is not oily, doesn't smell like sunscreen, and is protected," raved one Amazon reviewer. 

For the best anti-aging skin care, look no further than this Neutrogena Good Housekeeping Seal-holder. According to both Lab and consumer tests, this SPF 30 formula hydrates and firms skin, smooths wrinkles, and absorbs quickly without irritating skin, despite being loaded with anti-aging retinol. It also has over 1,500 reviews on Amazon, so it's no wonder our readers love it so much, too.

A great vitamin C serum brightens skin and fades dark spots, and this one is packed with L-Ascorbic acid that's effective but won't irritate skin. "It firms and brightens skin, and leaves it supple and glowy," senior Beauty Lab chemist, Sabina Wizemann said. Added vitamin E nourishes the skin, and Ferulic acid stabilizes the serum for the best results possible. 

When we tested the best night creams, this clean formula blew away the competition, boosting hydration by over 40% in just six hours. Testers loved that the formula absorbed quickly and that a little goes a long way, so the pricey formula actually lasts. It's packed with Caudalie's star ingredient Resveratrol, which is derived from grapes and uses the same regenerating process that allows grape vines to live up to 100 years — just imagine what it can do for your skin.

The benefits of silk pillowcases go way beyond just beauty sleep. They're proven to have anti-aging qualities by preventing wrinkles and fine lines, and give you healthier hair by reducing bedhead, frizz, and breakage. Our readers can't stop buying this Good Housekeeping Seal holder: It's is the best silk pillowcase you can buy, and since it's backed by the Seal, if it's defective, we'll refund you out of our own pockets.
