We hope you love our recommendations! Some may have been sent as samples, but all were independently selected by our editors. Just FYI, BuzzFeed collects a share of sales and/or other compensation from the links on this page.
1. A "flossing toothbrush" with two layers of bristles — regular firm bristles, and longer ones that are ten times thinner to clean deep in between your teeth and gums to mimic flossing. Reviewers love how deep the clean feels, and also how soft it is on sensitive teeth!
Mouthwatchers is a small business established by Ronald Plotka, DDS, that specializes in antimicrobial toothbrushes designed to get deeper cleans even patients with "great" dental hygiene might miss with traditional brush and floss routines.
I personally bought this a few months ago and love it! I use an electric toothbrush usually, but I feel like I'm getting a much more satisfying clean from these?? Especially because I tend to get yellow stains between my teeth no matter *how* much I floss, and these bristles seem to actually target that a lot more effectively. I've switched to using this in the morning and the electric one at night and definitely see a difference in that area in particular.
Promising review: "This was another one of my TikTok purchases! I was skeptical but my kids hate flossing their teeth so thought this might help in between making them floss. They work amazing! My kids said they could see and feel a different on the first use and I agree! They are definitely with a try! I would suggest not pushing too hard, those tiny bristles really get in there and if you push too hard you nights be sore like I was. It felt like after going to a dental cleaning." —Amy N.

2. COSRX Snail Mucin 96% Power Repairing Essence, a lightweight hydrating face serum designed for *all* skin types reviewers swear by for healing acne scars, fading dark spots, and smoothing fine lines. Users with sensitive skin especially appreciate how gentle it is compared to competitors, and a lot of them mentioned seeing results within the first few uses!
I use this on my skin and definitely have noticed results! While it didn't help kick my stubborn pre-period hormonal acne, it has done *wonders* with reducing redness on my face, particularly around my nose, and in dealing with my pores. Since I started using it, my primer and foundation goes on a whole lot smoother, and I'm struggling a whole lot less to cover my pores. After using it a few weeks, I read the advice of one reviewer to put this on when your face is slightly moist from washing, rub it in, let it dry, and then put your moisturizer on top of it — I've found that it's what got me the best results!
Promising review: "I caved to the TikTok hype and now I am obsessed, lol! I have extremely sensitive skin but this was the first product that I didn’t have to go through a 'getting used to' phase." —Shelby
Get it from Amazon for $12.49.
3. The internet-famous Revlon oil-absorbing volcanic face roller you simply swipe over your face like a magic wand that makes excess oil disappear — super convenient and *way* less wasteful than using blotting strips and time wasting than fancy powders that need a ton of blending work.
Promising review: "First off, if you have extremely oily skin, this. is. it. I was so tired of getting blotting powder/wipes. It felt wasteful and always left residue on my face. I saw this on TikTok and NEEDED it. It was backordered but then I got an email saying it was in stock and I was SO excited. Not only is it affordable, but it's washable, which helps you save money and be less wasteful." —Kelsey B.
Get it from Amazon for $12.89.
4. A lil' polar bear hydrating eye stick for some sweet, sweet relief when you wake up with puffy, aching eyes. This formula is blended with Iceland glacial water to help tighten skin and tackle dark circles so you look and feel more ~refreshed~.
Promising review: "I have always had serious dark circles and bags under my eyes and this has really changed this for me. The results are incredible. The puffiness is gone. The dark circles are hardly noticeable. My sensitive skin has not broken out. I never write reviews, but this was so good that I had to write a review. This actually works." —Ben
Get it from Amazon for $9.99.
5. A set of DEET-free handy mosquito-repelling bracelets you'll definitely want to invest in this summer — these use essential oils, including citronella, to help stop those teensy vampires in their tracks.
Check out a TikTok of the mosquito-repelling bracelets in action.
Cliganic is a small business that specializes in all-natural personal care products.
Promising review: "I moved last year from Southern California to North Carolina. Bugs of all types have always been attracted to me but the amount of bites I got last summer was WILD. Someone gave me one of these types of bracelets to use one day and it seemed to work SOOOOOO I decided to buy myself an arsenal to prepare for this summer. I read the reviews and about 99% of them had great results. I've only used this bracelet twice but both times I was outside and un-touched. Delivery was very quick so that was a plus. I'm not fond of the smell, I'm hyper sensitive to smells, but I'd rather have the odor than being chewed alive." —Tracey Agopian
Get a ten-pack from Amazon for $9.99.
6. Brazilian Bum Bum Cream, a cult-favorite moisturizing body lotion infused with caffeine, guarana extract, and coconut oil to simultaneously tighten *and* smooth skin. Reviewers are also obsessed with the soothing "sunshine" smell (with some replacing their perfume with it altogether!).
Promising review: "Like so many, I was brainwashed by TikTok into buying this rather expensive lotion...then I bought one for my mom and one for my sister and five more for myself as they became harder to find. My favorite thing about it is the smell. Lightly tropical/coconutty but nothing overwhelming. Every time I wear it people say, 'What are you WEARING?' like I have some amazing perfume on. Besides that, it really is a great moisturizer. I’m not usually a sucker for marketing but this was so worth it." —Kristen
Get it from Amazon for $22.
7. A ridiculously charming octopus-shaped blackhead remover you can use to gently scrub as part of your skin routine or in the shower to remove excess sebum to exfoliates pores and pull out blackheads, whiteheads, and other miscellaneous gunk from the day that you'd rather evict.
Promising review: "I saw this on TikTok, it works great so far." —MarMarManuel
*Another* promising review: "After just two days of use, this adorable little octopus has done wonders for me, smells great too. Here's how I used it: I wore down the stick just a little to where the texture from the salt is visible, scrubbed around on my face so there was plenty of product, then I used my fingers to gently massage all the gunk away. Rinse, pat dry, and enjoy the softness. Highly recommended for people with sensitive skin like myself." —LuckLocust
Get it from Amazon for $12.50.
8. A painless, mint-flavored teeth-whitening pen reviewers swear by as an alternative to pricey professional treatments and strips. This gets results from the very first use, lightening up years' worth of stains from coffee, tea, wine, or just, you know, existing as a human with teeth.
Promising review: "I have to say, I was skeptical about this product from all the TikTok hype about it but after trying it out, it really does work. I’ve used whitening strips before but those usually hurt my sensitive teeth and I hate the taste of some of the other gels on the market but this one was super easy and didn’t hurt my teeth at all and didn’t taste much different than my regular toothpaste, since I got the mint-flavored one. I used it for a few weeks before my brother’s wedding and it worked like a charm. I noticed visible results in only a couple of days and was able to keep using it until I reached my desired shade of white. 10/10 would recommend for anyone with sensitive teeth and tastes!" —Victoria Bravo
Get a two-pack from Amazon for $15.95 (clip the $4 off coupon on the product page for this price).
9. A facial ice roller you can stash in the fridge or freezer to help with all *kinds* of miscellaneous summer annoyances, like sunburns, overheating, and heat-induced migraines.
Promising review: "I was skeptical about this product. I wasn't sure how it was much different than rolling any other frozen thing on your body. I'm beyond pleasantly surprised. I've used it for sinus pain, migraines, swollen neck glands, under-eye circles/bags, inflamed acne, TMJ pain, etc. Not to mention, when I used it on my face, it leaves my skin feeling tight and wakes me up in the mornings. It also stays cold for forever but never sweats or leaves water behind. It's like magic. I also bought one for my mom who suffers from nerve damage in her arms and legs. I think it'll really help when she has bad pain days." —Jessica McRee
"Another TikTok find. I love this product. Helps with redness and inflammation. I used it after I put serums on my face, then after I put my eye cream and face lotion on. Has helped with inflammation of pimples and decrease pore visibility!" —Makenzie
Get it from Amazon for $16.14+ (clip the 15% off coupon for this price; available in eight colors).
10. A delightful little tool called the Bug Bite Thing that suctions on all kinds of bug bites to reduce swelling, itchiness, and redness.
Bug Bite Thing is a family-owned small business established in 2017 that specializes in bug bite relief products.
This works on mosquitoes, bees, wasps, biting flies, sea lice, and more (although TBH, if this list of bugs gets any longer I may just stay indoors forever!!).
Promising review: "I bought this because I saw it on TikTok, and have been having issues with mosquito bites. Used it a few times to relieve itchiness and I am convinced it works! Have been recommending it to my family and friends. Read the directions and follow them carefully. Don't use this on your face or neck, or other sensitive areas. Don't do a lot of suction, just a little bit. And do it a few times if needed. Great invention!" —Joe
Get it from Amazon for $9.95 (available in three colors).
11. A bottle of Elizavecca Hair Treatment, an Olaplex-like repairing mask infused with collagen ingredients and protein extracts that will help restore hair health and reduce shedding. All you gotta do is apply it on wet hair after a shampoo, wait five minutes, and rinse it out.
This is designed to work on all hair types, with reviewers with 2b–4c curls mentioning it worked for them!
Promising review: "I have tried everything on the market to fix my damaged, bleached hair that keeps breaking off. I stumbled across this hair treatment on TikTok. I had never heard of it before but decided to give it a try. I used it for the first time yesterday and I couldn't believe how amazing it made my hair feel and look. It's sooo soft, shiny, bouncy and nourished. My bleached rat's nest now looks and feels like hair again. Even my boyfriend noticed a huge difference in my hair. I’m going to buy a lot more of this product. I’ve been really frustrated about my hair for years now because of all the damage. Now I can finally relax and enjoy my new hair." —Eline

Get a bottle from Amazon for $7.29.
12. A stick of Body Glide anti-chafing balm you can apply between your thighs or under your bra to avoid all that skin irritation in ~hot spots~ you get in the summer.
I swear by this to the point where if I can't find it in the morning of a run, I just won't go out, LOLOL. My boobs chafe SO BADLY under my sports bra bands, no matter what kind I'm wearing, but putting on a tiny bit of this before I leave works like a charm. Absolutely no more friction and no more going "OW OW OW" in the shower because my literal boob wounds were stinging.
Promising review: "This was a TikTok buy and it was worth it. Highly recommend it. It does the work. Long lasting and not sticky at all." —EBATL
Get it from Amazon for $8.99.
13. Peach Slices Acne Spot Dots, a hydrocolloid sticker that you can apply straight onto a zit to flatten it, reduce redness, and even suck the gunk out of individual trouble spots overnight. Personally *love* to see a problem magically disappear while I'm snoozing.
Peach & Lily is a skincare brand founded by celebrity esthetician Alicia Yoon that specializes in toxin-free, vegan beauty products made with recyclable packaging. The company plants a tree with each order, and a portion of its proceeds have gone to to Restore NYC since 2016.
Check out a TikTok of the acne spot dots in action.
Promising review: "This brand is so affordable and works just the same as the more expensive brands. I go through them so quickly so this is a plus! I’m generally a picker at my zits, but if I can get to one of these dots in time I save my face a lot of irritation and pain. I wear them at night and sometimes during the day, only takes about two to get rid of those pesky whiteheads, sometimes more for a big zit. They really suck everything out." —Savannah Wilson
Get a pack of 30 from Amazon for $4.88.
14. A pair of popular cushioned "recovery" sandals perfect for anyone who is craving all the cute spring fashion with a side of ridiculous comfort. (And pain relief!) Not only are these super adorable, but reviewers with pain from plantar fasciitis, bunions, spondylilothesis, and other chronic conditions absolutely swear by them, with a ton saying they're like walking on ~clouds~.
Promising review: "Total comfort and instant relief from plantar fasciitis. I will order more." —mrs flores
"I have ordered several pairs trying to find the one that lives up to its hype, well this one is it. Super cushy, fits true to size — I ordered the mauvish pink colored one and love it. I will be ordering a black pair. I have a heel spur and planters fasciitis so regular flip-flops bother me after wearing several hours, these do not. Very pleased with this purchase and highly recommend." —leah
Get it from Amazon for $24.99+ (available in women's sizes 5–12 and 21 colors).
15. Juno & Co.'s Clean 10 Cleansing Balm, a game-changing makeup remover made with a blend of pearl barley and vitamin E that reviewers adore for getting that ✨ CLEAN clean✨ feeling — it's designed to leave zero residue or oiliness, *plus* brighten skin and reduce hyperpigmentation and dark spots.
Juno & Co. is a small business specializing in personal care and skincare products.
Promising review: "I LOVE THIS PRODUCT!!!! I found it on TikTok and OMG!! It works so well. I don't have to sit there and rub the crap out of my eyelashes to get the waterproof mascara off. I will admit, it doesn't take 100% of the makeup off but about 95% of my makeup comes off. It is not water-resistant, as emulsifying it with water helps take the makeup off. I have not found a better makeup remover, and yes that includes Micellar Water (which also works well but leaves my skin feeling oily). With this cleansing balm my face feels hydrated and smooth. LOVE LOVE LOVE IT!!!!!!!! 1000/10 would recommend!!!" —Deetje Frederick
Get it from Amazon for $14.99.
16. A stainless-steel tongue scraper that a lot of reviewers bought to prevent bad breath, but ended up loving even *more* because it made their mouth feel so squeaky clean (and, in a lot of cases, made their taste buds experience flavor a lot more intensely!).
DrTung's is a US-based small business that specializes in oral care products.
Promising review: "On the list of things TikTok made me buy ... You guys!!!! I don’t know why I waited so long to use one of these, but here I am, AMAZED!! I recommend it. True game-changer!" —Aliyah Lofton
Get it from Amazon for $8.49.

Promising review: "So, I purchased this product after seeing it on TikTok. This spray works VERY well with not sensitive skin. For me, I have not experienced ANY breakouts, nor have I experienced any rashes. Overall, it's AMAZING, and I use on the daily." —GoodLife7
Get it from Amazon for $6.65+ (available in five sizes).
18. A portable handheld fan that's also a flashlight that's *also* a power bank for phones, all of which to say is that this tiny gadget is officially working overtime. Travelers especially love all three of these deeply convenient functions!!
Check out a TikTok of the portable fan in action.
Promising review: "Our vacation planner suggested getting something like this for when you're waiting in line at an amusement park when the sun is out. Best advice ever. I used this when we were at Disney this past year. It's lightweight and doesn't weigh you down. The fan has adjustable speeds and includes a phone charger via USB A port and a flashlight function. Love that it folds up nice and small, great fan that I'd recommend to anyone!" —Andrew
Get it from Amazon for $19.99 (available in four colors).
19. A truly multi-talented set of cooling towels you can use to beat the heat — all you have to do is wet these, and they get chilly, perfect for draping on your head, neck, or other overheated areas. Once the chill runs out, you can wet them again to get it back!
Promising review: "I saw these recommended on a TikTok for disabled people who can't regulate their temperature in the heat, and omg, was it worth buying them. You just add cold water, and it's like an ice pack without the burning of the ice. They worked great for cooling my arm after the Covid shot! Excited to use them all summer!" —Muirgen Neal
Get a set of four for $19.99+ (available in 12 color combos).
20. A set of satin pillowcases that not only have a cooling effect but are soft on your skin and create less friction for your hair so it won't get as tangled while you sleep.
21. A set of itty-bitty dermaplaning razors you can use to take care of those lil' unibrow hairs that keep dodging your tweezers or work whatever face fuzzies you might want to take care of in a gentle way.
This tool also helps soften skin by gently exfoliating as you use it!
Promising review: "I saw these on TikTok and was skeptical, but they work so well. I use them for any facial peach fuzz and to shape my eyebrows, and they're perfect." —Megan Kopicko
Get a set of three from Amazon for $5.94.
22. A set of exfoliating gloves for the bath or shower you can use to ~deep clean~ all over your body, letting you get extra specific about the exfoliation pressure because you're using your own hands to do it. These also come in three different textures — light, moderate, and heavy — so you can get one to best match your skin sensitivity.
Evridwear is a small business specializing in gloves for work, personal care, and weather use.
Promising review: "This is one of my favorite purchases. Not gonna lie, TikTok made me buy this. So I buy it, and I’m still a little nervous because it’s literally a glove. But nah, I used it with liquid body soap, and I’ve never felt so clean in my whole life. I got out of the shower feeling like a freshly birthed baby. My skin had never felt so clean, and I questioned how I went 32 years without this." —Brittney
Get a pair from Amazon for $8.99 (available in three textures, various colors, and as sets of two or three).
23. A set of sunscreen reminder stickers — these UV stickers have SPF recognition and will change colors to let you know both when your SPF is working, and then again when it's time to slather more sunscreen on. Each sticker is water-resistant and works for up to twelve hours. NOT TODAY, SUN!!!
Check out a TikTok of the sunscreen stickers in action.
Promising review: "After yet another bad sunburn, even though I'm trying VERY HARD to keep sunscreen on, I bought these. The first use was at Disneyland on a 90-degree zero-cloud day. This helped so much! I kept an eye (as did my friends) on the dot so we all knew when to reapply sunscreen, and not one of us got burned. I also used these on a weeklong hiking adventure in Utah, which was also in the 90s with an extreme UV index. None of us got burned, so all in all, this is one of the best inventions!" —Catherine Shock
Get a 16-count from Amazon for $15.99.
24. A sleek time-marked water bottle that says "hydration, but make it chic." Reviewers love this bottle not just for the chic frosted, minimalist look but because it's super lightweight, leakproof, and motivational re: keeping yourself fully watered.
Promising review: "Saw it on TikTok and thought it would be a great bottle for work. It is very sleek and lightweight enough to carry when you have other items in your hand. I love the modern look, and it cleans very easily! The time increments motivate me, ordering again for myself and gifts. Fast delivery and very nice packaging." —Rosa
Get it from Amazon for $19.99 (available in three colors and two sizes).
25. Or a sleek flat travel water bottle designed to fit neatly into bags and backpacks without disrupting the ~rectangular flow~ of your books and laptop. It's super lightweight, too, making it ideal for travel and people who are out and about all day.
Promising review: "TikTok made me buy this water bottle, and I’ve never been more pleased with a purchase. It was delivered exactly as expected, even better. The size is perfect for inside a purse, book bag, or suitcase. I ordered the gray, and it's so understated. Beyond satisfied with this TikTok purchase." —Christina Carson
Get it from Amazon for $24.99 (available in six styles).
26. A bottle of Drop It, a natural wine sulfate and tannin remover that works its magic on your glass in just 20 seconds — instead of reaching for more expensive wines with fewer sulfates, you can enjoy a reasonably-priced summer rosé knowing you've spared yourself the infamous post-wine headache or allergic reactions.
It's also much more cost-effective and environmentally friendly than wine wands or other competitors — a single bottle of this can treat up to 55 glasses of wine, as opposed to wands that can only do a few glasses each before they get tossed. Drop It recommends 1–2 drops for each glass of white wine, 2–3 for a glass of red, and 7–9 if you're treating the whole bottle at once. Once it's in the glass, swirl it lightly for 20 seconds, and you should be raring to go!
Promising review: "I ordered this product after seeing it on TikTok with further investigation. And I must say it does work. I love sweet wine but will always get a headache the next morning (one glass). After using, I did not have one the next morning 😊." —Theresa B.
Get it from Amazon for $13.99.
27. A gentle bubbly clay mask designed to help remove blackheads and minimize the appearance of pores, but most importantly, to let you cosplay as a happy lil' cloud.
Check out a TikTok of the foaming mask in action.
Promising review: "I love this stuff! I received some as a gift and then purchased it for my daughter from Amazon. It feels like a clay mask going on, and then it starts bubbling and turns to a thinner substance when it's done. I feel like it is very gentle on my face. My skin feels amazing after I wash it off. It feels like I used moisturizer, even though I did not. I hear these masks are very popular in Japan." —L. Shea
Get it from Amazon for $9.15 (available in packs of one, two, and three).
28. A firming eye cream made with vitamin C, vitamin E, rosehip seed oil, and hibiscus flower extract to brighten and firm that sensitive skin around your eyes and neck, not just on a day-to-day basis, but a long-term one, too.
29. Tower 28's SunnyDays Tinted Sunscreen Foundation is perfect for anyone looking for no-fuss, lightweight, protective coverage — this rocks some SPF 30, is easily buildable, and reviewers with sensitive and acne-prone skin *swear* by it.
Tower 28 is a vegan, cruelty-free small business that specializes in products for sensitive skin.
Promising review: "Needed a new tinted moisturizer and heard great things about this via TikTok. I got the shade PCH and it blends in so nicely into my skin. My typical shade is Fenty 290 or 10/11 but I am pretty pale so PCH is perfect! Not orange! " —KWally21
Get it from Sephora for $32 (available in 14 shades).
30. A spray bottle of SoCozy Curl Spray Leave-In Conditioner, which is beloved by kids and adults alike — this lightweight formula is designed to spray in your hair before bedtime to prevent bed head frizziness and tangles by restoring and detangling curls, but a lot of reviewers use it to define their curls as part of their morning haircare routines, too!
Check out a TikTok of the curl spray in action. This is designed to work on all hair types, with reviewers with 2a–4c curls swearing by it!
Promising review: "Amazing!! I had NO idea that my frizzy-haired little girl had beautiful curls. I went down an Instagram rabbit hole and saw a similar girl show how her frizz was curls. I ordered this!! My mind has been blown!! This has changed our lives. It smells so good! It is easy to use and air dry before my daughter woke up with terrible bedhead that looked like this! Now it is gorgeous soft curls. We will definitely buy again and tell everyone about this product!!" —Amazon Customer

Promising review: "This stuff is magic. I am not kidding you, this is my first Amazon review ever. Just a few weeks ago my nails were brittle and peeling, I always had my nails done and they were pretty much destroyed… then I saw this on TikTok and decided to give it a try and I legitimately have never had healthier nails in my life! If you’re thinking about buying this… buy it!" —Jocelyn Nackley
Get it from Amazon for $9.90 (available in four sizes).

Promising review: "I fell for a TikTok star’s recommendation, and am happy I did. This is the most I’ve ever spent on a moisturizer, but I will never go back! This stuff is amazing. It keeps your skin hydrated. It’s thick but doesn’t feel like it once you put it on. Worth it!" —Shealen
Get it from Amazon for $21.99.
33. A jar of Aztec healing clay masks that essentially suck the gunk out of your pores like a vacuum, and will also help reduce the redness and ache of acne lickety-split.
People in the reviews also sing its praises for reducing the size of their pores! Many advise mixing the mask with apple cider vinegar for best results.
Promising review: "This does exactly what you have seen on TikToks and reviews! My skin is so soft and clean after each mask. I use this to treat skin that I shave, and the shave is smoother and closer. I will always keep this as a part of my regimen." —Joanne W.
Get it from Amazon for $14.95.
34. A battery-operated flexible rotating fan so versatile it's about to become your warm weather BFF — reviewers attach it to strollers, car seats, treadmills, tents, or even just plop it on their work desks for an extra breeze. It even comes with a built-in light for extra visibility at night!
Promising review: "I used this fan when I went to the beach with my 7-week-old son! I attached it to his stroller, and he stayed cool the whole time he was outside. Since returning, we use it in the car, for stroller rides, and I even use it when I’m hot in the house! The bendable legs make it easy to attach to any surface or allow it to stand on a flat surface. All around best purchase I have made this summer! Will be purchasing another!" —Jessica
"A good purchase. I would repurchase this! The best thing to ever go viral on TikTok. Even in freezing weather, my little one sweats in his car seat, and he becomes the crankiest pants ever.

Promising review: "So happy I saw this on TikTok! I was skeptical about the product because I am a very heavy sweater. There has been no deodorant that has helped this problem, but these Sweat Block wipes have literally been the best thing I've found that has made the quality of my life so much better!" —Amazon Customer
