Just make sure to use sunscreen with this since it can make you a bit more sensitive to the sun.

Promising review: "This has been a game changer for my skincare routine. Dealing with scars and uneven skin tone used to be a struggle, but this magical elixir has truly transformed my skin. Its lightweight texture feels like a treat upon application, and the quick absorption means no sticky or greasy aftermath. I've noticed a remarkable difference in the appearance of my scars and stretch marks, and my skin feels more hydrated and radiant overall." —Kate

PSA: There's a chance that the included Velcro-like adhesive can become dirt-traps when the filters are removed. Also, some reviewers wrote that the adhesive peeled the finish off of their fan during removal. If you’re scared of that happening, you can install these filters with Command strips instead!

Promising review: "I wasn't sure what to expect when purchasing these, but now they are a staple in every room of our house. Within three days, the air smelled more crisp and was easier to breathe in our home. So simple and effective!" —Haylee Marez

Promising reviews: "I have never seen my sink so clean! It removed the limescale with a regular washcloth and a little scrubbing." —Cndrla

"I need this in bulk!! I have tried so many cleaning solutions to get out hard cooking stains on my stove top, and nothing worked! This stuff took it right out without a problem!!" —Micaela Gunderson

Promising review: "So I decided to put these to the ultimate test for 4th of July underneath my white, semi-sheer swimsuit. I wore them out in the Florida heat in the ocean all day, and they did not budge or peel off. I thought for sure these would take skin off by the time I got home because I just couldn't believe they stayed on the entire day (humidity is real). I was able to remove them with ease. I washed them with warm water and soap and let them dry, and the next day, they were super sticky, like they were brand new out of the package again. Buying these forever." —Marisa

Promising review: "If you use St. Tropez tan products or any fake tanner, do yourself a favor and try this. This stuff is AWESOME. It dries quickly, lasts longer, does NOT make your skin stinky, applies evenly, and you get a fair amount of product!! Other tanners I’ve used become VERY noticeable when they start fading. Gross hand lines, patchy white spots, etc., but not this stuff. The best one-hour tan I have ever used!" —Review Writer 

Get it from Amazon for $10.49+ (available in seven shades as well as a mist and rinse-free style).

Promising review: "I have a long-haired cat, and when spring hits, there is a ton of hair left on my rug and couch for a couple of months. I tried sticky strips, but they did not do a great job. I ordered this tool and was blown away by how great it worked. It not only picked up the hair and stored it, but it also kept on working until all the hair was gone from my couch. I love it, and I am very pleased with [how easy it is] to clean it up and throw the hair away. I give this a 5-star rating." —gcommon

Caffeine can brighten skin and temporarily minimize the appearance of stretch marks and cellulite if that’s something you’re looking for in a product. Read more about the skincare benefits of caffeine at the Cleveland Clinic.

Promising review: "I am surprised when a product really does what it says, and this cream tightened skin as promised and somehow smoothed out some light cellulite on my legs. I keep looking at the backs of my hands, being surprised at how smooth and tight the skin looks and feels. At 48, I don't have much in the way of wrinkles or loose skin, but I can see a difference on the backs of my hands at times, even with all the kinds of treatments over the years. This cream zapped that in one treatment!" —Kindle Customer

Promising review: "I have been using this mascara for years, and it has never disappointed me. From the moment I received it, I fell in love with the results it delivers. This mascara makes my lashes look thick, full, and voluminous, giving them that perfect fluttery effect. What I love most is its consistency; it stays on all day without flaking or smudging, even in hot and humid weather. I can trust that my lashes will look flawless from morning 'til night. What's even better is that this mascara is extremely affordable, making it a steal for the quality it offers. I've tried many high-end mascaras, but none have matched up to the performance and value of this one. Overall, I highly recommend this mascara to anyone looking for long-lasting, voluminous lashes without breaking the bank. It's my go-to choice, and I can't imagine using anything else!" —xstArrx

BuzzFeed editor Kayla Boyd wrote an in-depth Essence Lash Princess mascara review.

Promising review: "Very satisfied. I tried everything to remove the black mold with no success. This product actually worked to remove the black mold. I applied the gel to the mold and left it to sit overnight. I was amazed the mold wiped off with a rag." —Robin S. Johns

Promising review: "Wow! Bought this little steamer and am really impressed. I did one go on my brothers' couches, and [there's a] difference. It could use one more go to get to the 'looking like brand new,' but this is amazing!!! When you watch the video in the product description, there is something oddly satisfying about watching the dirty water get suctioned in after spraying the surface you are cleaning, but I must admit I didn't believe it would work that well. Well, it does!! Just like advertised! I am so impressed. If you are considering this cleaner, get it; you will not be disappointed." —edina bajraktarevic

Get it from Amazon for $99.99 (available in two colors).

Promising review: "I’m pretty sure there is magic in these. I have spent so many hours scrubbing at different spots on my area rugs (compliments of my dog's sensitive stomach), and there are still spots that just won’t come clean. You literally lay these down, step on them for a few seconds, and walk away. I generally leave it for 24 hours, but I’m not sure if that’s really necessary. The next day, you can see the stain on the pad, and the rug is spotless." —MM

Promising review: "I have tried IGK, Living Proof, Not Your Mother's, Amika, and so many others, but THIS LASTS THE LONGEST! I am impressed by this product. Don't listen to the haters because I have severely fine and oily hair, and this product allows me to last for one week without washing, and it gives me volume without the toxicity of spray dry shampoo." —473X

Get it from Amazon for $18 (available in three shades).

Promising review: "I’ve used this product for about two months now. I try to remember to apply at least twice a day. Not only is my skin clearer, but the overall texture is much smoother and softer. I highly recommend giving this lotion a try." —Amazon Customer

Promising review: "I get corns on the bottom of my foot. This has been going on for 30 years. I’ve tried all the pads sold in drug stores. None of those are anywhere as good as this brand. They stick to the skin very well, and the medication really works on the corns and the thickened skin around them. Well worth it." —Al Symbal

Promising review: "My go-to cleansing oil. It melts makeup and SPF quickly and without much effort. I like using it more as a skin cleanser than a makeup remover just because it has helped my skin glow by making my skin texture better and getting rid of blackheads!" —Ravishankar Rao

Promising review: "I had no idea that cleaning a Keurig was a thing. I bought these because I saw them on TikTok, believe it or not. I wanted to give it a go because my Keurig isn’t that old, and I didn’t think it would do anything. IT WORKS SO WELL! My Keurig wasn’t as nasty as some I’ve seen, luckily. I would highly recommend. Keeps everything running correctly and clean." —Lauren

Promising review: "Best foot callus remover I have ever used! I read a lot of the reviews before purchasing this product. Most callus removers I have purchased in the past were not very effective. So, I was encouraged by the reviews. I saw that a lot of reviewers mentioned being very careful not to leave it on longer than three or four minutes. My feet were the softest they had ever been. Love love love." —Cheri whisker

Promising reviews: "Works great for my curly hair. My go-to product." —Audrey Figueiredo

"This stuff is wonderful. The smell, the de-tangling ability it has, plus I love how soft my hair is. My curls aren't stiff. And on the days I want a little more hold or crispness, I just mix some of my firmer hold mousse in with this. I wish I had known bout this product sooner. Thanks, TikTok." —Angelia Taggarrt

Promising review: "I had a horrible gray ring in the bottom of my shower that was impossible to remove. I tried the Dawn Dish Soap method (with a lot of scrubbing) and toilet bowl cleaner to try to remove the soap scum. My next step was to tear out and replace the shower pan and tile. I figured this was my last chance. I ordered the Wet and Forget Shower Spray, really coated the shower walls and floor pan, and walked away. I CANNOT begin to tell you how happy I was to rinse down the walls sometime later and watch all that crud roll right down the drain!! This is the best product I have ever used in my life!! Works great and no toxic fumes!!" —Amazon Customer

This formula is designed for all hair types.

Promising review: "This product has a light but really lovely scent. I absolutely love it! My almost-waist-length hair was seriously damaged by my last hairstylist. I've tried everything to make my hair shinier and more manageable, with less frizz. I've been through countless deep conditioning treatments with little results...until I found this! As a point of reference, I'm in my early 50s, so I have far from 'virgin' hair. If mine looks this great, that says a lot! My only wish? That it came in a bigger tube/bottle!" —C. Fordham

Fellow BuzzFeed writer Jenae Sitzes is a fan of these sponges:

"I picked up this color removal sponge from Amazon after hearing about this hack on TikTok and can testify that it actually works SO well. I'm *so* bad about cleaning my brushes (I know...shameful), and this makes it super easy to clean a brush in a matter of seconds. So, even if I'm trying to do a *slightly* more elaborate eyeshadow look for the day, this makes the process of switching colors as quick and painless as possible. Also, it's *super* lightweight, and I've already tossed it in my bag and brought it on vacation with me. This is one of those products I won't be traveling without in the future if I plan on doing eyeshadow at any point — and it means you only need to pack one or two eyeshadow brushes!"

Promising review: "This product makes it even easier for me to be lazy when it comes to cleaning my brushes. It also allows me to use the same brush for a makeup look since I can swish away a previous shadow and move on to the next. Great buy. Super easy to wash." —Azaleah Bumpus-Barnett

This medium-coverage concealer can be applied with your fingers or a brush.

BuzzFeed writer Heather Braga loves this beauty product:

"I've personally tested this out, and it has become an essential part of my daily routine. As a mom of two, I gotta just say I am TIRED. So tired that I'm not sure what my face even looks like without bags under my eyes — that is, unless I've got the Catrice "Instant Awake" on. A little really goes a long way and has great coverage. I wore it throughout my sister's wedding weekend in Aruba and, despite the heat, it stayed perfectly in place. An incredible product for an even more incredible price... 10/10 from me."

Promising review: "I believe I was born with dark circles under my eyes, and I have spent the last 50+ years looking for something that will cover my dark circles. I’ve spent a lot more money on products that do a lot less. And I was very hesitant to buy something so inexpensive as I thought it would not work. I was surprised to find my circles a lot lighter, and my eyes are looking much more alert and younger. I’m very pleased with this product!" —Lafinrsm

Get it from Amazon for $6 (available in four tones).

Promising review: "I use these about once every other week or so. I have seen drastic improvements in my skin. After one use, my skin was not nearly as dry and flaky. My face seemed a lot more supple and plump as well. After continued use, I have noticed the fine lines on my forehead are less noticeable, and the overall texture of my skin is smoother compared to bumpy-looking. I also noticed I don't look as tired even though I'm exhausted, lol. My uneven skin tone has improved, and my face has brightened somewhat. I live and work in the city, and I think you can tell by my skin's appearance, but after using these, my skin looks fresh and soft and has a nice glow to it even after one use. I will continue to keep these masks stocked in my vanity." —Rachel

Promising review: "I have a 19-year-old primary bathroom toilet that had accumulated some nasty stains over time, and regular toilet brushes and cleaning products just would not remove them. I decided to try this pumice stone, and it worked like a charm! Given the nature and severity of the stains, it required some elbow grease. But 10 minutes later, I have a new-looking bowl, and I see no signs of scratching." —Happy Retiree

Promising review: "I tried EVERYTHING! I tried tree tea oil and various other products for years. Nothing worked. The reviews were so great on this that I decided to try to cure it one more time. But when you have had a condition for 35 years, you aren't too hopeful! I followed the suggestions of some of the reviewers and cut my toenails (I only had it on my big toes) everywhere that the fungus was present, even below the quick. I started applying this gel, which is super easy to use. I swear to you that I noticed a difference after one application." —WIAPilot 

Promising review: "I’m big, so my inner thighs have always been darker than the other parts of my legs. I’ve tried other products for it, but nothing has worked. I HAVE BEEN USING THIS SOAP FOR THREE DAYS AND OMG!!!! My inner thighs are SMOOTHER, and they are ALMOST THE SAME COLOR AS THE OTHER PARTS OF MY LEGS. I'M SO SO SO HAPPY!!!! I hate that I didn’t take a before picture, but trust me!!!! BUY IT!!!! My face also looks brighter and fresher, agghhh!!" —Daphney

Promising review: "This is my daily go-to. It provides the perfect dewy glow to the skin without the glittery look that some other tinted moisturizers have. I don't wear a lot of makeup, so there are days I throw on my sunscreen moisturizer and put this right on top. It provides a beautiful, moist-looking shine, but no real coverage, though, so if you're trying to hide blemishes or skin discoloration, you'll still need to use a concealer or foundation base underneath. For a more made-up look, I will use my regular liquid foundation first and put this on top. It's literally perfection. I will always have this in my makeup bag." —Jsweep

Promising review: "These are simply awesome! Such a small thing can make such a big difference. At night, when I opened my eyes, I was flooded by little dots of light intruding into my space from all my electronics: the TV and cable receiver, the modem, the routers, the electric blanket control switch, the microwave, the smoke alarms, cell phones, etc. And it doesn’t take much to interfere with a good night's sleep. These will mute and soften those bright lights so they don’t bother you anymore. Thanks for a great 'little size, big results' product!" —Ziapetlady

BuzzFeed Shopping contributor Jasmin Sandal says, "My hair is the ~perfect~ combo of wavy, curly, and frizzy, and this drugstore product has been a holy grail of mine for some time. I've found that it's the only formula that will give me soft, naturally curly waves come the a.m., and since I'm generally a nighttime hair washer, I have the perfect excuse to avoid blasting my hair with heat. Before hitting the pillow, I like to run my fingers through my towel-dried hair with a pea-sized amount of this, flip my mane over, and then give the ends a good scrunch. In the morn, my hair appears shiny with defined, wavy curls — we're not talking HD — but they have a nice, soft definition to them that doesn't require much styling."

Promising review: "I've been using this for a while, and a lot of people ask what I use for my curls. I highly recommend. For reference, I have average/thin hair with 3a-style curls. This curl cream doesn't make my curls look greasy and doesn't weigh down my hair." —M.R.

Promising review: "I recently lost my edges due to low iron and braiding. I wanted to try something to grow my hair back. Within two months, I noticed a change in my edges. My hairline is fuller. This is a MUST-buy. My edges were very thin and braiding them made it worse. But using this changed my hairline life." —Missy

Promising review: "This product is so amazing for when your skin feels like it’s burning or it’s irritated. It has such a calming factor to it, and I really like the 'saltwater' scent." —kealsc

Get it from Amazon for $12+ (available in three sizes and a bundle) or Sephora for $12+ (available in three sizes).

Promising review: "Reliable for irritated summer skin. I get hives on my chest, neck, and inner elbow. I have been using this soap for years off and on. When I don’t use it, the hives come back. The soap keeps it in check. I gave a bar to my husband, who has a different issue, since this soap is good for all sorts of skin problems. It’s good for keeping down body odor, too." —KarenS

Promising review: "This is my favorite go-to eyeliner! Wings have always been part of my signature style, but over the years, I’ve developed tremors, and it became harder to draw them on. This was my savior! The stamps are so easy to use, and you know your wings are even without checking, which is a major confidence booster! This liner stays in place through everything, too! I’m talking water, sweat, crying, and even food mishaps. I’ll never use another brand again!" —Jessica

Get it from Amazon for $17.99 (available in three sizes).

Promising review: "Wow! Wow! Wow! This is now a must-have in our kitchen! It’s been used to clean our water bottles for sports, water bottles with straws, dental retainers, pickling jars to get that lingering smell out of mason jars, stainless steel pots that were discolored, coffee-stained cups, and also some China that had some gunk on them. What else can it be used for? We’ll keep searching!" —M.E.

Promising review: "This stuff works! I'd never had a wart in my life! At first, I thought it was a small callus, but as months went by, it got larger. I started to google and realized I had a plantar wart on my thumb! So I got the Freeze Off and thought, 'This has to work!' Nope! I tried the Freeze Off three times, and nothing! I then realized the same thing was happening on my other thumb, a small callus, but I knew that the wart had spread! Now I was desperate to get rid of them and knew I had waited too long! I bought the invisible strips, and they removed my small wart in four days and my big wart in eight!! I couldn’t believe it. I left strips on for two days, then pulled back the dead skin with a cuticle clipper and reapplied! My bigger wart was a little tougher to remove, and I had irritated my skin trying to cut it out, so I left it alone for a few days before reapplying a strip, and by the second 48-hour treatment, it was gone! I thought my skin would be damaged, but it looks like nothing was ever there!" —Audrey N.

Have coilier hair? Try this paddle brush instead!

Promising reviews: "I've had my eye on a Dyson Airwrap, but given the cost, I figured I'd try this while I save up. This thing is fantastic. I have waist-length hair that's naturally straight but gets frizzy when damp. I've had salon blowouts that have left my hair looking great, but I simply can't manage a round brush without it getting tangled in my hair. This device has been a game changer. It works best if you air dry for a while before you use it, then use it to finish your style. My hair miraculously doesn't get snarled in it, and it leaves my hair looking like I've had it professionally styled. I love it, and I'm no longer interested in blowing $500 on a Dyson. Highly recommend!" —Ilsa

Promising review: "I suppose it's my hearty German peasant ancestry, but I've always been a hairy girl. Plucking the more egregious of the thick black hairs is required at least two to three times a week. I'd been eying these razors for a while and finally took the plunge. I could not believe how easy and quick it was. After a couple of swipes down my cheek, I noticed that it was done. I thought it was going to take a lot more skill and time. So much easier than tweezers and depilatories!! Wow." —Tara D.

Promising review: "I did a lot of research to find a non-chemical leather conditioner for my couch. I applied it to a full-sized leather sofa as well as a large leather chair with an ottoman. I only needed to use a little bit, and they were shiny and smooth and looked brand new! Clean your leather first, then use a little bit of this with a lint-free cloth, and it will turn out beautifully. My couches were dry and silky smooth in about five minutes. Amazing conditioner! I HIGHLY recommend Leather Honey!!" —ASD1

Promising review: "If I could give this product more than 5 stars, then I would!! My husband has suffered from extreme dandruff/Psoriasis for years to the point that he would pick constantly at his scalp. I would be able to visually see large sores and peeling skin chunks constantly, no matter what shampoo/treatment he would use. I found this product by chance and told my husband about it, who was willing to give it a chance (he’d more than given up on finding a solution to his problem at this point). After two shampoos he said that he absolutely noticed a difference and did not feel that he had to scratch his scalp. His sores healed within a week, and now he has a clean, itch- and flake-free scalp! This stuff worked absolute wonders for us, and I would recommend it to anyone with slight dandruff issues to extreme psoriasis conditions!" —Tabitha C.

Promising review: "This thing is excellent. I just 'repaired' two cashmere sweaters and one modal-blend jersey top to like-new condition. The waste compartment fills up quickly and will start clogging the blades if not emptied frequently. I will share one trick I found for emptying the area around the blades. Remove the waste compartment and hold the unit vertically over a garbage can while turning the defuzzer on. Blades will spin, and the rest of the pills will fall out. Enjoy." —Fine Print Reader
