Amazon Prime Day runs from July 8 to 11, and it’s a feeding frenzy for beauty steals, so I’m here to help you spend your money semi-responsibly. I’ve combed through countless hot tools, dental devices, and skin care gadgets to find the best Prime Day beauty deals. We’ve tested everything here and would vouch for these products even without a markdown. (This is WIRED, after all.) I’ll be updating this list daily as more deals go live, so keep checking back.

If you’re shopping for other gadgets and gizmos, check out our Best Prime Day Deals roundup or our Prime Day liveblog.

WIRED Featured Deals

A Cheap Red Light Therapy Mask

An honorable mention in our guide to the Best Red Light Face Masks, this soft LED mask packs 630-nm and 830-nm light to support collagen production and treat signs of aging. Unlike some other models, this mask looks actually looks pretty cute while you wear it. It’s super popular because of its already affordable price, and it’s made even cheaper with the extra $100+ discount.

A Powerful Dyson Hair Dryer

This is a pared-down Dyson hair dryer. It just has one attachment, but offers the same fast drying and protects against heat damage. The machine measures air temperature over 40 times a second, regulating the heat to make sure it never gets too hot, and like Dyson’s vacuums, it has a powerful motor that spins at up to 110,000 rpm to fast-dry hair without the damaging heat.

A Hair Dryer for Sensitive Scalps

If you have a sensitive scalp like me, the Shark SpeedStyle Pro Flex is worth the investment. Shark’s Scalp Shield feature monitors heat 1,000 times a second to ensure it never exceeds 230 degrees Fahrenheit. It comes with four versatile attachments à la Dyson, and it’s surprisingly light (1.57 pounds). Plus, it folds up for easy travel or storage. I’ve tested the Dyson Airwrap, and this gets you there for way less cash.

The Best Blow-Dry Brush

Featured in our guide to the Best Blow-Dry Brushes, the Drybar Double Shot has three heat levels, reaching 275 degrees Fahrenheit at the top end, but it manages to not leave hair feeling fried. When testing, we got great hair results just using Drybar’s simpler settings compared to brushes with more options. The Double Shot made our reviewer’s hair nice and smooth while giving it volume, and managed to give less frizz than other models.

A Budget Blow-Dry Brush

We’ve tested a lot of blow-dry brushes, but the Revlon One-Step Volumizer Plus (8/10, WIRED Recommends) wins on value. It dries and styles at once, with a slimmer, 2-inch oval barrel that’s detachable and easier to handle than the original. The ceramic titanium tourmaline coating cuts down on heat damage, and four settings (plus a cool shot) give you all the control you need. At $46 (down from $70), it’s a steal.

Our Favorite Budget Hair Straightener

As seen in our Best Hair Straighteners guide, Conair’s Infinity Pro is the best hair straightener you’re likely to find for under 20 bucks. It not only heats all the way up to 455 degrees Fahrenheit, the little dial on the side offers a mind-boggling 30 set temperature points, so you can be sure to find the one that works for your hair.

A Water Flosser

I’m a devout flosser, and while this Waterpik isn’t a replacement for string floss, it’s a killer addition to my dental care routine. The rotating nozzle and three pressure settings blast gunk from places threads can’t reach. One fill gives you 45 seconds of powerful spray, which is all I need. It’s compact, waterproof, and cordless. It charges fast in just four hours and comes with a travel bag and tip case. Ideal for tight counters and travel. My gums have never been happier.

A Sonic Toothbrush

I’ve tested a lot of sonic electric toothbrushes, but I keep circling back to the Philips Sonicare 4100. It’s gentler on gums than oscillating brushes, dead simple to use, and packed with features that matter. You get a pressure sensor, a two-minute timer, two intensity modes, and a two-week battery life. It even reminds you when it’s time to change the brush head. At $40 for Prime Day (down from $50), it’s the one I’d grab.

A Beard Trimmer

This is one of the most versatile beard trimmers thanks to the dozen or so attachments in the box. They’re easy to swap, but you can also use the trimmer without the guard for the closest shave, and it doesn’t nick or pull. You can use it plugged or unplugged (we rarely had to plug it in), and it’s completely waterproof.

An Affordable Soothing Balm

I love this lip mask. It’s featured in our guides of the Best TikTok Gifts and Best Lip Balms. A little goes a very long way—I’ve had my current jar for three years—and the formula is thick, but melts down quickly. This luscious treatment is flavored and scented, but not tinted. It’s soothing on dry lips (and even cuticles in a pinch) thanks to ingredients like coconut oil and shea butter. It also doesn’t get much cheaper than this. —Louryn Strampe

Snail Mucin For You Skin

If you’re interested in the benefits of snail mucin, the Cosrx Advanced Snail 96 Mucin Power Essence is a must-try. Packed with an impressive 96 percent snail secretion filtrate, this serum delivers hydration and works wonders in repairing your skin, all while being free from added fragrances. Regularly priced at $17, it’s now available for nearly half off during Prime Day—an opportunity to stock up on this cult-favorite slime.

A Cheaper Dyson Airwrap

The T3 Aire 360 (9/10, WIRED Recommends) matches the Dyson Airwrap in power and aesthetics but at a price that feels way more justified. It comes with fewer ceramic attachments than its competitors, but with two curling barrels, a concentrator, and an oval brush, it’s more than enough for a salon-worthy blowout. The rose-pink finish is adorable, and it stashes easily in a drawer. WIRED reviewer Nena Farrell’s one complaint about the tool was the cost, but with this deal? No notes.

The Best Curling Iron For Long Hair

We’ve dubbed the Bio Ionic Long Barrel Styler the best curling iron for (wait for it) long hair. The 8-inch ceramic barrel wraps large sections quickly and tames frizz while you style. It heats up to 430 degrees Fahrenheit, and the sculpted cool-touch grip makes styling feel ergonomic. Plus, it’s dual voltage, so you can pack it for international travels.

A Viral Curling Iron

This curling iron went viral last year for how it easily creates both waves and perfect little ringlets. Simply clamp your hair, press the button, watch as it wraps your hair around the wand, and let it go to reveal a corkscrew curl. Try it yourself, it’s half off right now.
