1. A pack of sweat-wicking bra liners made from cotton and bamboo to absorb the dreaded under-boob sweat that appears when it's hotter than all heck outside. Reviewers confirm the liners are comfortable, don't smell, and provide sweet, sweet relief!
Plus, they're machine washable!
Promising review: "I bought these for a vacation in Florida. I sweat A LOT. It's just the way I'm made. Humidity and heat are miserable for me. Boob sweat rings on my shirts are common and embarrassing. These liners were AMAZING! So comfortable. I didn't even notice them except to notice the lack of embarrassing rings and dripping sweat. Make sure to measure to get the right size." — Kindle Customer

2. A portable car vacuum, a must-have for anyone who is the designated driver of their friend group but usually just ends up apologizing for the mess and saying, "I swear it's not always like this." Now your car will be clean and ready for a five-star rating. This vacuum is only 2.4 lbs, comes with three different-sized attachments, and plugs into your vehicle's 12-V Aux outlet.
Promising review: "LOVE this little vacuum! The long cord works great for my full-size SUV. The extension hose and attachments work great together to get in all the tight places. Filter is a breeze to clean, especially with the small cleaning brush. Mine came with a tote bag that I can store it in and place in the back for easy access which allows me to use it while simply killing time here and there while waiting on kids to finish their activities or during my lunch hour. 5-10 min a week is all I need to keep the Tahoe looking good inside. Never embarrassed to give rides to others. I'm always getting compliments on how clean it is. This handy device really does make it that simple!" —Deanna
Get it from Amazon for $33.99+ (available in three colors).

3. A bottle of signature Fur Oil ready to tackle many of the skin issues you've been covering with long pants and sweaters. Reviewers say it can help clear pores, minimize ingrown hairs and bumps, and even reduce razor burn. You can use it ALLL over your body (yes, even your pubic hair) so you're ready to slip on your bathing suit at a moment's notice.
Promising reviews: "I am prone to ingrown hairs. I have VERY coarse pubic hair and every time I shave, I get razor bumps and ingrown hairs as the hair starts to grow back. Very embarrassing. This has led me to lean more toward trimming than shaving. I decided to try to shave one more time — well, I used Nair and removed my pubic hair from my genital area. I used fur oil every day morning and night after the removal, and even as the hair grows back and beyond. I would also exfoliate the area about two to three times a week with a coffee scrub that I got on here. The hair has started to grow back with zero bumps or ingrown hairs. It has actually been over a month and still no issues. This has never happened to me before. I have not removed hair down there and have not had ingrown hairs and hair bumps. This is a new experience for me, and I am loving it. I have even removed hair again since then and still no problems. My only complaint is the size of the bottle, and the smell is so-so. It is a very small bottle for the price. I will continue to use this combination of products, though, because I know it works. I am satisfied." —In the know
"Recommended to me by my waxer. I was a little hesitant at first because it's pretty expensive, but I haven't had a single ingrown hair since using this oil. I am diligent on application of the oil, and it's been great. It lasts — I've been using it for about two months, and there's still a ton in the bottle." —Megan Harmeyer
Get it from Amazon for $26+ (available in two sizes).
4. A Carpe antiperspirant hand lotion for anyone who deals with sweaty hands that are only made worse when you're nervous and have to shake somebody's hand. Simply use a pea-sized amount to reduce the sweaty and clammy feeling.
Promising review: "I’ve suffered with sweaty hands for all of my life. It’s an issue that has caused me embarrassment and anxiety where there should be neither. I’ve only just started using this lotion, but I can tell it’s making a difference. It definitely has a distinct drying effect and makes my hands feel smooth." —Gary
Get it from Amazon for $19.95.
5. A stain- and odor-eliminating spray that provides a quick one-two punch to not only remove the spots but also smells that may have ended up in your carpet from your furry friends. It lifts away dirt and grime while releasing enzymes to break down the odors.
Promising review: "When it comes to tackling tough pet stains and odors, this product is my go-to. The Rocco & Roxie Stain & Odor Eliminator has truly been a lifesaver in my home. With its powerful enzymatic formula, it effortlessly eliminates even the strongest of odors, leaving my carpets smelling fresh and clean. I can't tell you how many times this product has saved me from embarrassing pet accidents. The best part? It's super easy to use! Just a quick spray and the stains and odors magically disappear. The only thing I would love to see improved is the spray nozzle. While it gets the job done, a better nozzle would make the application even more convenient. But overall, I can confidently say that this product is a game-changer for any pet owner. —Sarah C.

Promising review: "My nails and the skin around my nails looked a dry, scaly mess. I also had painful cuts and hang nails. I was embarrassed to show my hands. After some research, I purchased solar oil. After using about 5X’s my nails look so healthy! I’m shocked! It has not even been an entire week of me using and my nails and cuticles look amazing. I did not expect this oil to hel my nail, I thought it was just for cuticles. To my surprise, my nails also look moisturized and healthy. Will purchase again!" —C. Price

7. An earwax removal kit you'll be talking your friends' ears off about because of how clean it will leave you feeling.
Promising review: "I've had excessive wax problems for over 20 years. The first time I had to deal with it I went to the doctor, and I remember it being EXTREMELY unpleasant and pretty embarrassing for a woman in her 20's. I vowed never again! Recently my ears have been plugged again, and a nurse told me to use this product first, and then come back and see them. Today after work, I decided to dedicate my evening to my right ear. I had used a different product a few months ago with no results so I was extremely skeptical. I placed about 6-10 drops into my ear, tilted my head & waited for about 15 minutes. Flushed with the bulb — nothing. Used 8-10 more drops and waited another 20 minutes. I could hear the "popping" sound in my ear and knew it was the wax breaking up. I was hopeful! Rinsed again with the bulb — a tiny bit of wax appeared. I was still clogged though & starting to lose hope. Used a few more drops and waited another 10 minutes. This time the popping and cracking was really loud. I knew it was working, but I couldn't flush the damn stuff out! After reading Amazon reviews about how to flush your ear I went in again. After positioning the bulb and squeezing as hard and fast as I could, I heard a 'pop' and a little tearing sound and suddenly I could hear everything! I grabbed some tissues to help gently guide the wax out and OH MY GOD it was gross and amazing all at the same time. I haven't heard this well in 20 years!!!
This product really DOES work as well as the reviews claim. As other reviews have mentioned the secret is patience & being diligent and forceful with the irrigation bulb. Uncomfortable for a little while, but well worth the results. I will never be without this product again!" —Kindle Customer
Get it from Amazon for $8.12.
8. A pack of unscented antiperspirant wipes said to keep sweatiness at bay for up to seven days!! Yes, you read that right. Just apply to any area where you sweat a lot before bed, let it air dry for five minutes, wash the treated area in the morning, and then go on living your best life.
Oh — and just an FYI you should "patch test" this on a small area of your skin to make sure you don't get any type of reaction.
Promising review: "I've had really bad hyperhidrosis since I was 12 (especially my armpits) and could never find anything that helps. After like 4 days of using these my pits are finally dry! I've been using them for about 2 years now. Even if I don't use them for a few days, my pits are still dry. I can finally wear fitted shirts without feeling embarrassed of my pit stains. Love these! I will say they do kind of dry out your skin but it's worth it to me." —Amazon Customer
Get a 10-pack from Amazon for $19.99 (each box lasts two months).
9. Or a pack of underarm sweat pads if your sweat is centrally located in your armpits. Place one of these pads between your skin and your shirt, and it will help absorb both perspiration and odor.
Promising review: "This underarm antiperspirant pad is very useful. I belong to the kind of physique that sweats a lot, and I sweat a lot, which is very embarrassing. After using this pad, the symptoms of sweating have been significantly reduced, and I will not sweat a lot. It is a very good antiperspirant pad." —Eleanore bradley

I’m glad I finally found something that has helped! I use this in combination with the body lotion! Which has helped a lot too! Definitely try it out! The bumps have mostly dried up and new skin has healed over, took at least one to two months to see results!" —Amanda
Get it from Amazon for $13.99.
11. A pumice cleaning stone you swish around the bowl to help remove all the rust, mineral deposits, and stains inside your toilet you thought were stuck there for good. Now, you won't have to tell your guests that the front bathroom toilet is "broken" when really you don't want them to see the state of it.
Use gentle back-and-forth motions to remove stains and deposits from inside the toilet bowl, and voila!
Promising review: "I have very hard water that leaves hard water buildup and nasty stains. It’s embarrassing to have guests over because the toilets are so gross! I have tried so many products and cleaning solutions — from natural essential oils to harsh chemicals so strong I was lightheaded for the rest of the day. I had many failed experiments and one that was semi-successful. The before picture [above] of the toilet was after five sessions of an hour plus scrubbing with the semi-successful option (you can see where the ring is fainter to the left). Well, I tried out this pumice stone after reading about it in a BuzzFeed article, and honestly, the hype is real! It does take some elbow grease, but the after picture is from only 20 minutes of scrubbing, light enough that I didn’t break a sweat! The stone does get used up, but I think this one should last me a couple of years at least. So if you have embarrassing toilets, try this!" —Stephanie Ray
Get it from Amazon for $13.99 (also available in a two- and four-pack).

I’ve tried things here and there but nothing battled it as hard as this product. In just 3 months of using it once a day during my shower, it went away. If you're on the fence about which one to buy, do know this one works." —Jacqueline

Promising review: "When I say that my feet stuck to the sheets and I was embarrassed to wear sandals and get pedicures because of how bad my feet were, I know I needed to find something to help! I’ve tried foot wraps, I’ve tried gel callus remover, pumice stones, etc. This product completely fixed my feet on the first try. I was blown away by the amount of build-up it took off. And my feet feel like a newborn. They are so soft, and I cannot stop touching them! BUY IT, you will not regret it!" —Keisha Mae

16. A mold and mildew remover to easily remove the gross buildup in your shower and make it look as good as the day you moved in (or maybe even better). All you have to do is apply it, let it sit, and then rinse. Yep, that's it.
Promising review: "You guys. I’m embarrassed to even show you this. The grout around our tub was DISGUSTING. It was never caulked right and it got gross very quickly. I would scrub. The cleaning lady would scrub. It would get worse. Well, I came across this in a BuzzFeed list, and this stuff made me curious. I don’t know why it doesn’t have 10,000 good reviews. Seriously. All I did was squeeze it on and walk away. I let it sit overnight. Check this out. Buy it. Like today." —KarynB

Promising review: "I had left nail polish on my toes all winter. When I took the polish off my nails looked horrifying. Chalky white build-up, looked like they were going to break apart. I did a deep clean and applied 2-3x a day for a week. I then did another deep clean and filed off the top layer of my nails. They look almost back to normal. I wish I had a before picture. I was so embarrassed by how they looked. Very pleased with how they look now. They look healthy and ready for an upcoming vacation." —Lauren
Get it from Amazon for $16.03.

"I highly recommend this product. The instructions were super easy to follow, and it worked perfectly! I was a little nervous to pull the sticks out once the two minutes were up; however, it didn't even hurt. I expected it to hurt momentarily and my eyes to water, but neither was true! If you wanna get rid of them pesky nose hairs...snag this product!!!" —Julie J.

19. A volcanic stone face roller that'll remove all the oil and shine that appears on your face when you're out living your life. Reviewers like this option better than oil-blotting sheets because the ball pops out and can be washed, making it a reusable and more sustainable option.
Promising review: "This has transformed my makeup routine! My skin is so horribly oily, every day I was dabbing it, rinsing it off, or wiping the oil off with a tissue. It was so embarrassing to me. Now, I just go over my T-Zone with this roller, and my face stays dry all day; no more shine! Don’t hesitate to purchase this roller, it’s absolutely wonderful, and gets the job done!" —GLENDA GERDES

Promising review: "I received this product a little less than a week ago. I was hesitant to purchase at first due to the price, but after reading so many positive reviews and the before and after pictures people were posting, I had to try it. I was very surprised by the scent — smells just like rubbing alcohol. Very easy to apply and dries quickly. Does leave a slight residue. After just one day, I saw a difference! The bumps on my legs that had been causing years of embarrassment were gone. GONE! I am very pleased with this product. Wish it wasn't so expensive for how big the bottle is, but it really is worth it. *Don't forget to put lotion on after it dries, because it did dry my skin out the time I forgot to." —Amazon Customer

I love that now as soon as a white head shows up I just pop one of these on at night, and the next morning it’s looking amazing. I also have worn them during the day in front of people and it is subtle enough for me to not feel embarrassed wearing it. Thank you to the geniuses that came up with this technology!" —M

Promising review: "I used to be in sports all through middle and high school, and it really messed up my left foot overall especially my big toe. I was always embarrassed by my big toe during the summer that I’d put a Band-Aid over it to make it seem like it was injured. Finding someone to fix your toe is expensive, and I don’t have that kind of money at the moment. Started doing research on ways to do so and this one was the best way. Found this product with all the things one needs — applied it as directed, and it does take some practice but once attached it should not move. Your toes will hurt for a day. Like a dense pain. Not sharp. I saw a difference in about 2 weeks. I’m a month in on the most severe toe and no more ingrown toe nail!" —Sandra L.

Promising review: "It took two days. Only two days. The shoes I've had for work for almost a decade, full of funk, sweat, and vague scents of past sprays that didn't work (lavender-scented foot odor is not a solution), I looked for something better. I found these, got them, and put them in my shoes. I noticed a change after the first day. After day 2, it was completely odor-free. Couple this with some peppermint foot/shoe spray, and these 9-year-old shoes aren't an embarrassment anymore. Amazing product. I'm getting more." —Justin Bielak

I am able to hold my pee longer, which means I can actually make it to the bathroom without dribbling on myself. The best part is that just a few short weeks into the program you will have results you can feel. I think every woman who has ever had kids should try this, out.

30. Medicated, waterproof wart remover pads you apply like a bandage. It'll work to help remove that oh-so-annoying wart so you can get back to more important things in your life, such as playing fetch with your dog.
Promising review: "More than six years with a large, sometimes painful plantar wart on the bottom of my foot. The doctor tried freezing. I tried apple cider vinegar, aspirin, freezing at home, over and over again...nothing worked. Never showing the bottom of my feet, refusing to get a pedicure with the girls, and so, so embarrassed...It felt like I was doomed to have it for forever; it was resistant to everything. Literally six years of fighting it and on a whim tried these because of the good reviews. ONE APPLICATION. I wore the bandage overnight. I didn’t think it did anything, but a few days later the wart just came off. I know it’s silly to be so emotional over a stupid wart, but I’m telling you, I nearly cried. I’ve never been so happy with a product in my life. Highly, highly recommend giving these a try if you’ve got stubborn plantar warts." —Liz Dube

And if that doesn't convince you, maybe the before-and-after pic below will do the trick. 🤢
Promising review: "Take all my money! This tool is beyond amazing. I don't go anywhere without it! I used to think using a toothbrush to clean my tongue was good enough, but my husband gently pointed out that I needed more help. Ever since starting with this scraper, my mouth hasn't smelled at all. I use it regularly (about once every day, depending on what I've eaten) and it's saved my life. I'm not embarrassed or self-conscious when I'm talking to people up close. It's especially great for removing dairy products that stay on your tongue forever. I will never go without this tongue scraper." —Jennifer

Promising review: "Sometimes you eat something that is too rich on an empty stomach and wham — the pain, the bloating, the weird weird noises start. And then if you have this, within minutes it helps relieve the gas, bloating, and discomfort. Taking this is nothing to be ashamed about; it happens to everyone whether they like to admit it or not.
