Cold sores, yellow teeth, and rosacea are just some of the things I've found solutions for — you can thank me later.

Promising reviews: "Best exfoliator out there. I've been using this product for about five years and nothing else compares to its ability to get rid of dead, flaky skin. Other kinds of physical scrubs are harsh and can damage your skin. I'm in my fifties, and I use Retin-A, which leaves your skin a bit dry and flaky. This product helps to remove that and leave a smooth surface as well as prepare the skin for treatments, moisturizers, etc... My teenage daughter, who has acne, uses it and loves it as well. The key is to put it on your clean, dry face and rub gently. If there isn't a lot of dead skin, not much will come off. If you have a lot, then the little white pills of dead skin will roll off. Magic!" —Diane H. 

"I am obsessed with this stuff!! I only use it about once a week, but it works wonders!! Starting to break out on your back? This stops it before it gets out of control! Ingrown hairs on the bikini line? This exfoliates the skin so they are gone before you know it!! And lastly, of course, I use this on my face... my skin never looks better!! This is a MUST-HAVE in your skincare arsenal and not just for your face!! I wish I could give it more stars!!" —Basil Meadows

Promising review: "This stuff is miraculous! It sprayed out just fine. I started rubbing my feet, and layers of dead skin just fell right off. I wiped the product off with a wet washcloth and then raked my nails gently over the area on my feet, and more layers of dead skin just fell right off. I'm 51, and my feet were looking awful. I can't afford to get pedicures very often, so I thought the price of this foot spray was doable. I may never get a pedicure again! I'm so glad I found this foot spray and decided to give it a try. If you have dead skin on your feet that you want to get rid of, this is the right stuff!" —JHossman

Get it from Amazon for $5.48 (also available as a two-pack).

Promising review: "I have extremely sensitive teeth from over-whitening in high school, but this product has been such a lifesaver! I am a daily black coffee and red wine [drinker], so my teeth have taken a toll as far as staining goes. Seriously, I was very hesitant about getting this because of how sensitive my teeth are, but I wish I got it sooner! This is such a great product!" —Mimi Doherty

Promising review: "I love this product and have noticed a huge difference when using it consistently. I am on the younger side and don’t have the worst under-eye bags, but on those occasional mornings when my eyes are puffy with somewhat visible dark circles, this product definitely does the trick! Honestly, I love all the Good Molecules products." —Hayden Smith 

Promising review: “I tried EVERYTHING! I tried tree tea oil for years and various different products. 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. I started applying this gel, which is super easy to use. I swear to you that I noticed a difference after one application.” —WIAPilot 

Get it from Amazon for $16.97+ (also available with a nail file).

It's fragrance-free, and you can apply it morning and night. 

Promising reviews: "This neck cream works!!!... I am in my 60s, I sleep on my side, and have been a sun worshiper my whole life. Thus, I have deep wrinkles and fine lines on my neck and chest. The Firm Intentions neck cream was rich and hydrating, but was quickly absorbed...After using the cream for around ten days, I was very happy to see the deep wrinkles and fine lines were smoother and my skin was plumper. The fine lines were way less noticeable! I cannot wait to see the results after a month. I definitely recommend!" —Kari H.

"Game changer! ...Love it and have only been using it for about a week and already see results! Will definitely repurchase!" —Carline Trevorrow

Promising review: "I could not get rid of the cellulite on my legs. I started using this product six weeks ago and can noticeably see a difference. I apply morning and evening, before bed for optimal results. It goes on smooth and has a creamy, non-sticky feel. The smell is dreamy, and even my husband has commented on the improvement. Make sure you apply in a circular motion for optimal coverage, absorption, and circulation." —Amazon Customer

Reviewers with thin or fine hair LOVE this hair treatment, and various hair types from 3b to 4c say that it helped their damaged hair. Even folks with dyed or bleached hair say it's safe to use. TL;DR: It works!

Promising review: "Like many others, I tried this as a replacement for Olaplex. Honestly, Olaplex never had a great effect on my hair and certainly wasn’t worth the price. This did an unreal job on my hair!! I was skeptical (tried a little bit first because I was petrified it would burn off my hair and I would end up bald!) but, lo and behold, it was magic! My hair is so strong, silky, and healthy-looking after just one use. Plus, you can’t beat the price! Have already ordered another box. I should also add that I have curly/wavy hair that’s been colored to a light brown. Buy it!!" —BB

Promising review: "This product saved my skin. I seldom write reviews, but I just had to review this product. I’ve been struggling with acne for YEARS. I have very acne-prone skin. I get a new pimple almost every day, and it seemed like there was never a time I didn’t have a pimple on my face. Acne leaves super dark blemishes/scars on my face. I’ve tried all different types of moisturizers and cleansers. Nothing worked. However, I bought this serum on a whim. OMGGGG. Guys. Literally, my face stopped flaring within three days. I was PIMPLE-FREE FOR MORE THAN 48 hours (a new record). Exactly two months later, the blemishes have faded DRASTICALLY, and I have no active breakouts. This hasn’t happened in years. I truly and honestly think it is due to this product. If you are hesitant, don’t be, BUY IT! It has also helped my under-eye bags (use one drop for both under-eyes; pat gently with fingers.)" —Brandon

Promising reviews: "It really is amazing! The reviews are true. This is the perfect trimmer for the whole body, bikini/Brazilian included! It worked so well on all the sensitive folds and skin. No nicks and a nice close trim! The facial trimmer attachment just finishes off the job to make it nice and smooth. Definitely my go-to hair removal system for the [bikini area]!" —Sandy E'Bell

"I have very sensitive skin (psoriasis), so typical razors hurt to use. This was the exact opposite, and it gives a perfect shave!" —TT

Get it from Amazon for $19.99+ (available in two styles and 12 colors).

Promising reviews: "I could kick myself for not trying this sooner! It is my new favorite lotion... After one night of using this, I woke up to smooth, soft, moisturized skin that wasn’t itchy at all. This lotion goes on and absorbs beautifully. It’s not too thin or thick, and the scent is sensational... It’s not greasy or slick and does not have a residue that pills or transfers." —TickTockAlice

"INCREDIBLE BEAUTY PRODUCT!! Works like magic! I am 66 years old, and after using this moisturizer for only four days, I have not needed to use foundation makeup. This Medix retinol cream is a serious game changer!" —Nancy C. Trussell

Get it from Amazon for $19.99 (also available in multipacks).

As far as skincare goes, this is stuff is basically pure gold in bar soap form. ✨ You can use it on your face, neck, and all over your body as needed.

Promising review: "10-star soap. Love, love, love this soap. I have KP, which is a skin condition that makes the back of your arms look rash-y and red. I've tried everything. Glycolic, salicylic, retinol, and more. Nothing has ever worked until this. It leaves your skin feeling so soft and has taken away a lot of the discoloration. So happy I found this." —Sanctuarytampa

Promising reviews: "Anyone with dark under-eye probs like myself needs to have a brightener! I used to spend $40 on Becca, but this one is better in my opinion!! It’s very pigmented and covers blue hues in the corners of my eyes. It can be worn alone, but I prefer it under my concealer. It blends incredibly well, it's very creamy, and easy to apply. It will probably last me six months — a little dab goes a long way. It’s extremely buildable, too. I am just so in love. I’m a sucker for saving money and this purchase just saved me over $30. I will recommend it to all my friends and family. Just BUY it!" —Caitlin Newcomb

"Bought this after seeing an influencer use it on TikTok. This works really well. I can instantly see a difference when I use it under my eyes. For the price, this is a win-win. I had never heard of this brand, but I will be using their products more often." —Kerry C

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

I've just bought my third bottle and can confirm that this stuff is the real deal. My skin has become SO much softer since using this serum, and I've even noticed a few dark spots diminishing. But seriously, with how plump and baby-soft my skin is after a single use, I was immediately sold!

Promising review: "This is the best product I’ve used on my face!!! RUN AND GET THIS! I have sensitive skin. Day four, I see a huge difference in my skin; it’s smooth, hydrated, and dark spots are disappearing. It’s magic in this bottle." —Tareika

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 to be very careful not to leave it on longer than three or four minutes. My feet were the softest they have ever been. Love love love." —Cheri whisker

Get it from Amazon for $9.99 (available in three scents).

Promising review: "I placed this order after seeing it everywhere on TikTok... and boy am I glad I tried it! I was initially skeptical of trying anything on my feet.. and let’s be honest, the peeling feet pictures are not for the weak :) .. but oddly extremely satisfying. I soaked my feet in the bag for an hour as instructed (super easy to use) ... two weeks later, BOOM baby soft feet...10/10 would recommend!! " —Alma Elias

Get two pairs from Amazon for $19.99 (available in four scents). 

Promising reviews: "AMAZING PRODUCT! I am amazed! I wash my face with Cetaphil gentle cleanser while in the shower, and immediately after getting out of the shower put BioOil on my skin. That is all I do. I do have a spot treatment from Neutrogena with 10% maximum-strength benzoyl peroxide for those SUPER STUBBORN pimples, but hardly use it since starting with BioOil. I will forever use this product and recommend when I can. I have olive-toned, freckled, medium to dry skin with oily nose and forehead, adult hormonal acne and hyperpigmentation. BioOil has given me a literal GLOW! I feel confident with my face again. I hardly leave reviews, but this product deserves it! Good luck on your healthy skin journey." —Amazon Customer

"Bio-Oil is the BEST skin product on the market. I use it twice a day, morning and before I go to bed. Small lines have disappeared. My skin is very smooth and seems to glow. A doctor recommended this to one of my friends who told me about it. I have bought several bottles as gifts. Be patient. It will take a few months for you to see notice the changes." –Amazon Customer

Promising review: "I wish I had found these sooner!! These cold sores were probably the worst I've had and wouldn't clear up or stop itching/hurting. I googled cold sore remedies, and these happened to pop up. After reading the reviews, I immediately ordered them. They came right on time, and I put them on before bed last night. It's been less than 36 hours, and these cold sores are already healing beautifully. I plan to order another pack or three, so I can keep one at home, one in my purse, and one in my locker at work so if I ever feel the warning tingle/itching of a new breakout, I can slap one of these bad boys on and get rid of it quickly! Highly recommend for my fellow cold sore sufferers." —Jessica Hill

Juno & Co. is a small business based in California.

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!!!!!!!! 1,000/10 would recommend!!!" —Deetje Frederick

P.S. These fizzing tablets work for Invisalign, retainers, dentures, night guards, and more.

Promising review: "I really loved this product. I am currently waiting for a new Invisalign set. My old Invisalign needed to be cleaned. I read the reviews and decided to purchase. OMG it worked! There was a fresh taste and they were clean. I wish I had found this product sooner. I did let them soak overnight only because I had been wearing them for the last four months. Nothing happened to Invisalign; there was no weakness or anything. Just very clean and fresh. If I could have given the product 10 stars, I would have." —Lisa R.

Promising review: "I used to pay a professional to dermaplane my face once a month to remove the peach fuzz, which makes me look older and makes the makeup application more cumbersome. I searched for years for a home product to use to save money and time. This is the closest I have been able to get to professional dermaplaning in the convenience of my home, on my time/schedule, and at a fraction of the price. Love it!" —SEM1969

Get a three-count from Amazon for $5.94 (also available in a pack of nine).

Promising review: "The power of the hair identifier's spray is unmatched. Once you spray in any direction that has hair, it automatically identifies the hair that needs to be removed. It is easily sprayed on and easily wiped off. No extra residue. Comes with four blades, and I say these blades are soft and gentle, yet they get the job done. Not sure why no one ever thought of coming up with a hair identifier spray. Great value and smells like baby powder. Great quality." —Karine

Rubbing alcohol-based products (like Tend Skin) can help prevent an infection of an ingrown, but can’t prevent an ingrown itself, according to Cleveland Clinic. 

Promising review: "After many years of razor burn on my face/neck, I finally broke down and bought this per a friend's recommendation. I have sensitive skin and had given up hope that anything could help. This totally changed my outlook on shaving. My neck especially would be the worst. I dab it on immediately after I rinse and dry, post-shave. It does burn a bit but that goes away pretty quickly. Totally worth it to not have razor burn/bumps anymore. I only apply it once after shaving even though the directions recommend repeat applications the following day. Go ahead and purchase, you won't be disappointed!" —bill nye

I have shades Ube Vanilla (a gorge sheer burgundy color), Dulce de Leche (a sheer nude that smells like caramel heaven), and SOS Vanilla (a classic clear), and they have quickly become purse essentials for me. So much so that when I lost one, I *quickly* ordered a replacement! These lippies make my lips sooo smooth and I love how the color shows on my darker skin tone. It really makes lip care easy to do on a daily basis — truly a game changer!

Tower 28 is an Asian woman-owned beauty brand founded by Amy Liu.

Promising review: "I love how hydrating and refreshing this LipSoftie is. It gives that pretty shine and all the lip love you need in a lip treatment. I am pretty much obsessed with how it feels. It doesn’t pill or feel heavy. It is very lightweight. I can’t get enough, and I’m pretty sure I need the whole collection now!" —Stacey K.

Promising review: "This stuff is absolutely amazing. I was one step away from going to the dermatologist. I had severe dandruff that was so bad I could shake my head, and it would come off. With just a few uses per week, I got rid of all my flakes. My scalp also stopped burning from dryness. My hair has never been healthier." —Moo Moo

BTW, people also love this for helping heal piercings. (Note: This product has newer packaging that you might receive instead of the older bottle shown above!)

Promising review: "This spray is amazing. I had a rash on my face and it disappeared after one use of this spray. I had a stye in my eye and the skin around the eye was irritated. This spray fixed not only the irritation but the stye went away as well. Any sort of blemish or acne is taken care of with this simple inexpensive spray. Great for after-sun care or workout redness. Everyone loves Tower 28's expensive SOS spray. The SOS spray contains hypochlorous acid, which is the exact same ingredient in the Briotech spray for much less money. It’s a miracle worker." —Squid466

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

Get a pack of 14 from Amazon for $7.08 (also available with invisible strips).

Promising review: "Unfortunately, I, like many, suffer from bad breath and have tried so many things to stop it. I read that sometimes it's the germs on your tongue that can cause it, so I [kept] trying to brush my tongue. Of course, we all know how that ends — gagging, watery eyes, and it still looks like that gross film is on your tongue. I finally decided that maybe it was time to get a tongue cleaner, and it had to be a stainless steel one because they are easier to clean and sterilize. This product is really easy to use, and I can get very far back on my tongue without activating my gag reflex. Also, it doesn't have the feeling like brushing with a toothbrush does. This cleaner just glides across my tongue, taking all the icky germs and bad breath with it. I love my nice new fresh breath and bolster of confidence!" —jordanb

Promising review: "I am so glad I gave this product a try, as it works amazingly well on my fine, oily hair. I have used just about every dry shampoo product on the market, and this is by far the best one yet. My hair looks beautiful, and I can now go nearly a week without washing (while still having absolutely gorgeous hair)! I used to have to wash my hair every other day when I was using my former favorite dry shampoo (and it made my scalp itch on day two). This product is definitely worth a try; it may soon be your favorite!" —Melanie Havert
