Beauty deals are among the few Amazon Prime Day sales that are great nearly across the board. Whereas some tech products are only on sale because they're old, or the deals are the same you can find year-round, the beauty deals we've spotted are almost always on new and trendy products or classics we wouldn't want to go without. We do test a lot of tech professionally, but we apply that same testing protocol to the beauty products we use in our everyday lives. Here are some deals on our tried-and-tested favorites.Make sure to check our list of the Absolute Best Prime Day deals for more verified discounts on the gear we recommend.Best Beauty Device DealsRemington Shine Therapy Hair Straightener for $28 ($6 off)Photograph: Kat MerckRemingtonShine Therapy Flat IronThis is the best budget hair straightener I have ever tested, performing as well on my 3a curly hair as flat irons five times the price. This Prime Day deal is not the most dramatic discount, but you won’t find a better straightener for under 30 bucks. The 1-inch plates heat up to 410 degrees Fahrenheit in just 34 seconds, smoothing even the most recalcitrant frizz and leaving hair shiny and healthy-looking. —Kat MerckItalia Diffon Supreme Ionic XL for $135 ($34 off)Photograph: Louryn StrampeBellissimaItalia Diffon Supreme Ionic XLI love this lightweight, user-friendly diffuser and reach for it multiple times per week. It's especially good for curly hair. It isn't the fastest diffuser I've ever used, but it's gentle on my tresses and lets me dry them without feeling guilty. Goodness knows I put my hair through the wringer already, but I don't feel like I'm adding to the damage when I use this on wash days. —Louryn StrampePhilips Norelco Multigroom for $65 ($25 off)Photograph: Matthew KorfhagePhilipsNorelco Multigroom 7000, MG7790Reviewer Matthew Korfhage says the Philips Norelco Multigroom is the best deal in beard trimmers. It’s a versatile tool that is not only quiet but also operates at high RPM, delivering a close cut without any nicks when used guardless. The attachments, including the convenient nose hair trimmer, are simple to swap, and the impressive five-hour battery life means you won’t have to worry about recharging during short travels. The only minor inconvenience is that it doesn’t come with a storage case for all the guards—but that’s nothing a ziplock bag can’t fix. —Boutayna ChokranePhilips Sonicare 4100 Electric Toothbrush for $40 ($10 off)Courtesy of PhilipsPhilipsSonicare 4100 Electric ToothbrushThe Philips Sonicare 4100 is my top choice for a midrange electric toothbrush, delivering a gentler sonic cleaning experience that beats standard oscillating models. Its compact brush head is ideal for those with narrower mouths, ensuring every molar is reached. Key features include a pressure sensor that reduces vibrations when you brush too hard, a two-minute auto-shut-off timer, and two intensity settings (low and high). With its BrushSync technology, it tracks your brushing time and reminds you when it’s time to replace the brush head. Plus, a single charge lasts about two weeks. —Boutayna ChokraneCanopy Filter Showerhead for $100 ($50 off)Photograph: Matthew KorfhageCanopyFiltered ShowerheadReviewer Matthew Korfhage is our resident showerhead tester. According to him, Canopy is one of the few shower filters he has tested that effectively removes nearly all chlorine and chlorine compounds from water. The filter needs to be replaced approximately every three months. With this discount, it’s almost like you’re getting an extra filter for free. —Boutayna ChokraneIRestore Elite for $1,709 ($890 off)Photograph: Julia ForbesPhotograph: Julia ForbesPhotograph: Julia ForbesiRestoreElite Laser Growth Hair SystemThe iRestore Elite is one of our top red light therapy devices for promoting hair growth. This FDA-cleared helmet combines 300 lasers with 200 LED lights, providing full scalp coverage and enabling hands-free treatments. Its three wavelengths—625, 655, and 680 nanometers—are within the optimal range. The rechargeable battery is reliable, offering up to two weeks of use on a single charge. Note: The typical price for the iRestore Elite is between $1,799 and $1,899, so this offer isn't actually a huge discount, but it’s still cheaper than a trip to Turkey. —Boutayna ChokraneSolawave 4-in-1 Radiant Renewal Wand for $110 ($59 off)Photograph: Nena FarrellSolawave4-in-1 Radiant Renewal WandSolawave’s 4-in-1 Skincare Wand is a TikTok bestseller and our favorite red light therapy device for treating facial spots. It has 16 mini LEDs that emit a single wavelength of 630 nanometers, which helps reduce puffiness, fade wrinkles, and soothe the skin. Plus, it offers vibration and warmth therapy for a relaxing experience. Three of our WIRED testers have reported positive results, noting improvements in skin tightening. —Boutayna ChokraneTherabody TheraFace Depuffing Wand for $130 ($40 off)Courtesy of TherabodyTherabodyTheraFace Depuffing WandThe TheraFace Depuffing Wand is a must-have ice roller that doesn’t melt and stays cold. It offers both hot and cold therapy to help reduce puffiness, improve circulation, and enhance the absorption of skincare products. The curved precision tip is designed to fit the contours of your face, and it features three preset temperature levels that remain consistent during a six-minute session. It’s one of my favorite travel gadgets since it’s compact and TSA-friendly. —Boutayna ChokraneGHD Chronos Max for $259 ($120 off)Photograph: Kat MerckGHDChronos MaxThis is a legitimately great deal on GHD’s most high-tech hair straightener. It only has one heat setting, 365 degrees Fahrenheit, which it maintains through sensors that measure the 1.75-inch plates 250 times a second. It’s not for everyone—it did not work wonders on my 3a curly hair when I tested it—but if your goal in using heat tools is to prevent damage, this is one of the best options out there. It also comes in a smaller, 1-inch-plate version for $14 less. I think it’s worth getting the larger plates to get the job done faster, but the 1-inch plates are easier to maneuver. —Kat MerckBest Skincare and Haircare DealsVacation Classic SPF 50 Sunscreen Lotion for $36 ($12 off)Photograph: Louryn StrampeVacationClassic SPF 50 Sunscreen LotionI love this giant jug of SPF 50 sunscreen. It smells like the beach, it applies evenly without leaving a white cast all over my biracial olive skin, and it absorbs quickly. I put it to the test at the beach on Memorial Day with a very fresh stomach tattoo and managed to avoid a burn. (This is not advisable behavior, but don't ever say we don't try products out before we recommend them.) —Louryn StrampeOlaplexNo. 4 Bond Maintenance ShampooSeveral Reviews team members swear by Olaplex, so I'm buying the Wash & Shine kit while it's at it's lowest price.LaneigeLip Sleeping MaskThis is actually the lowest price we've seen for this viral lip balm, which goes on sale often and lasts seemingly forever.Color Wow Dream Coat Supernatural Spray for $20 ($10 off)Photograph: Kat MerckColor WowDream Coat Supernatural SprayThis viral heat-protectant spray is a Prime Day sale staple. It’s one of the rare products that works for all types of hair, from fine and easily tangled to thick and curly, as it’s lightweight and effective without leaving heavy residue. It must be used on wet hair only and needs a blow-dryer to “activate,” but it does a great job at keeping styles sleek and less frizzy in the face of wind and/or humidity. —Kat MerckBest Makeup and Fragrance DealsClinique Black Honey Almost Lipstick for $18 ($7 off)CliniqueAlmost Lipstick Tinted Lip Balm (Black Honey)This iconic tinted lip balm looks great on every skin tone. It's been popular for decades and will probably outlast every beauty trend for the rest of time. It's moisturizing, and the blue undertones mean that your teeth will look whiter, too. I won't be the only product reviewer stocking up on this today, especially at this price. —Louryn StrampeVacationBody MistLouryn's signature scent smells like banana, coconut, and a little bit of chlorine—summer in a bottle.PhlurFragrance Discovery SetKat likes this for travel because there is a TSA-allowable scent for every mood, event, and activity, and they're not too heavy and not too light.Power up with unlimited access to WIRED.
