If you spend much time on Instagram, there’s a good chance you’ve noticed some celebrities promoting the HiSmile Teeth Whitening Kit. Kylie Jenner is the most famous of the celebrity endorsers, and she swears by it. When a celebrity endorses a beauty product, you can’t help but take notice, so we decided to check it out. Find out in this HiSmile product review what we discovered by using its kit and more info about other products in its catalog.
What Is HiSmile?
HiSmile is a brand of whitening products founded by two Australians in 2014. The founders built the company from the ground up and quickly turned a profit by selling various teeth whitening products.
The HiSmile PAP+ Teeth Whitening Kit is the most popular offering of the brand and the main reason for its success. It is a do-it-yourself tooth whitening kit that you can use in the comfort of your own home. The kit consists of six applications, and each application takes ten minutes. The company promises the teeth will be up to eight shades whiter after following the protocol.
However, the brand expanded its catalog with other products also meant to whiten your teeth, like toothpastes and mouthwashes formulated by the Hismile Research Centre and clinically proven to be effective, quick, and safe.
How Does HiSmile PAP+ Teeth Whitening Kit™ Work?
As we have mentioned before, the PAP+ Teeth Whitening Kit is a DIY whitening kit that consists of six applications called whitening pods and a LED light mouthguard meant to whiten your teeth when combined and used for 10 minutes.
But, does HiSmile work? Well, the product has always been a great success for the brand, but its team decided to improve the formula to get better results. After years of research and development, they created an expert-level formula used by customers worldwide and by dentists. This new formula consists of these three powerful ingredients:

- Hydroxyapatite (Nano): The nano-synthetic hydroxyapatite possesses remineralizing effects that gradually replace minerals into the protective layer of enamel.
- Phthalimidoperoxycaproicacid: The name PAP+ stands for this ingredient's name because it's the most crucial ingredient of this new formula. The PAP is an organic peroxy acid that has the ability to activate the oxidation reaction to start the whitening process effectively.
- Potassium Citrate: It has a dual-action purpose as it helps relieve pre-existing sensitivity and provides long-term protection from external stimuli that cause discomfort.
This new formula works quicker and better than the previous one because the PAP+ is meant to oxidize tooth stains without releasing harmful molecules known as free radicals, which can harm the enamel and cause tooth sensitivity. In other words, when you whiten your teeth with the new PAP+ formula, there’s no erosion or damage to the enamel to get whiten teeth, and the outer layers of the tooth remain intact and protected. The PAP+ targets tooth stains internally and externally without compromising your dental health, causing no irritation or sensitivity and the LED helps accelerate the whitening process (that’s why you only need to wear the mouthguard for only 10 minutes).
The brand has been deeply involved in this formula, and that’s why it was also clinically trialed and tested by dentists to ensure that it worked perfectly and didn’t cause any adverse effects. Moreover, it’s vegan-friendly, peroxide-free with no SLS, alcohol, parabens, or PEG.

How to Use the HiSmile Teeth Whitening Kit
One of the first questions that come to mind before purchasing a product is if it’s going to be easy or difficult to so: how to use HiSmile?
We can tell that is very straightforward by taking a quick look at the Hismile instructions, but you will need to follow a series of simple steps. It is essential to follow all the steps exactly to achieve optimal results.
- Step 1: Brush your teeth gently for 2 minutes so you don't hurt your gums. This will remove bacteria that could impede the whitening process. Make sure you rinse your mouth out thoroughly after brushing, so there is not any toothpaste left.
- Step 2: Make sure the batteries are in the LED light and attach it to the mouth tray.
- Step 3: Place the gel in the top and bottom of the tray and put it in your mouth.
- Step 4: Turn the LED light on and wait for ten minutes. The light will turn off when the ten minutes are up.
- Step 5: Remove the tray from your mouth and rinse the gel out using warm water. That's all you need to do when using this kit.
How Often Do You Use HiSmile?
The previous formula of the HiSmile Teeth Whitening Kit required using the kit every day for six days to achieve optimal results; however, with the new formula, you will be able to see the results in just one or two uses. After that, it is recommended to use the kit before an event or every few months to maintain overall whitening, but if you want to maintain the results, the brand recommends using the PAP+ Toothpaste or the PAP+ Mouthwash every day.
How Long HiSmile Lasts
HiSmile claims that results last up to two months, depending on the foods and beverages you consume.
There are several items you need to avoid in order to maintain your results. For example, coffee, tea, soda, dark juices, and red wine can stain teeth, so don’t drink any of these beverages. You should also avoid popsicles, tomato sauce, blueberries, and beets if you want to maintain the results. Also, smoking stains teeth, so put down the cigarettes, or else stains will quickly pop up on your teeth.
Avoiding these foods and drinks is the first step in maintaining a white smile, besides using the PAP+ mouthwash or PAP+ toothpaste daily to optimize the results.

Other HiSmile Products
The most known product of HiSmile is their renewed PAP+ Teeth Whitening Kit™; however, this doesn’t mean that they don’t have more products available. In fact, they have some great products, all designed for whitening your teeth and protect your oral health.
- Day & Night Toothpaste: An everyday smile care routine that consists of two toothpaste tubes: one to use in the morning that protects your teeth from food build-up and the other one at night to fight the build-up of biofilm, which can cause tooth decay.
- PAP+ Toothpaste™: Focused on whitening and maintaining the teeth’ white shade obtained after using the PAP+ whitening kit, it also takes care of your teeth without causing any sensitivity or irritation. It was formulated by the HiSmile Research Center similarly to the PAP+ whitening kit and is peroxide-free.
- PAP+ Mouthwash™: As a part of the PAP+ HiSmile line, it is also meant to maintain the white shade obtained by the whitening kit. This mouthwash is a concentrated solution for daily use and is very straightforward. You only need to mix one full dropper of the product with 15ml of water and swish it in your mouth thoroughly for 60 seconds.



In addition, they are going to add new products in October. This new line focuses on oral health more than on whitening your teeth, and it consists of three following products:
- V34 Color Corrector: For neutralising yellow undertones and brightening dull white teeth.
- NHPro Enamel Care: For targeted enamel remineralisation, and managing sensitivity.
- HA5 Hyaluronic Serum: For hydrating gums, supported by antibacterial and anti-inflammatory effects.



Moreover, if you want to purchase more than one product, the brand offers oral health packs (The Duo and The Collection) with which you can get the products at a more affordable price than buying them separately and with some freebies included!

HiSmile Results: Before and After
Before purchasing a product like HiSmile, you want to know what to expect. Does the product really whiten teeth as much as the manufacturer claims? To confirm if it works or not, we recommend you to check HiSmile teeth whitening kit reviews before buying any product of this brand.
HiSmile promises to whiten your teeth in one use, that can sound impossible, but based on what we found online, it is true. In their HiSmile teeth whitening reviews, most people report that their teeth are lighter after using the product only once and also state that the teeth maintain that white shade if you keep applying the product.
The kit includes a shade guide you can use to compare the color of your teeth. Find your tooth color on day one, and then compare it to where you are on day six: you’ll likely notice a marked difference. In fact, most people report receiving some compliments after they are done using the kit.

FAQ
No, Hismile can’t damage your teeth or gums. However, you shouldn’t use whitening if you suffer from a serious gum problem, or you have recently had an oral operation.
Hismile products are totally safe to use as they are clinically proven to not cause any damage to your gums, teeth or soft tissues in your mouth.
It is not recommended to use whitening products during your alignment treatment. In one hand because your teeth are moving, and it can cause your teeth to have different tones of white when you finish your treatment as whitening is applied to the visible parts and during your alignment treatment your teeth are moving to the right position and there are parts that can’t be reached. On the other hand, some of the whitening ingredients can also damage your braces or aligners.
If you leave HiSmile on too long, it can cause teeth sensitivity as the formula is meant to be used following the instructions.
It will depend on the maintenance you do, but it’s meant to last between 2 weeks and 3 months. If you want to last as much as it can, it is recommended the daily use of the PAP+ Toothpaste or PAP+ Mouthwash.
This review is going to be for the HiSmile Teeth Whitening kit. This HiSmile teeth whitening kit has been talked about all over, whether it be the internet, mouth to mouth, the tv, and even billboards. It has been advertised on most social media platforms and multiple celebrities have posted about how they use this product. This product is a mouthguard that has a blue light and when you put the provided gel in the mouthguard and when the blue light gets turned on it is suppose to whiten your teeth. Advertised results showed extremely yellow teeth had been turned insanely white by the use of this product. Not only does the HiSmile business advertise how well their product works, they also made it so the process of the teeth whitening only takes minutes. Using celebrities, showing how white your teeth could be, and the process only taking minutes it was easy to get people to start buying this ridiculously priced product.
Because of all the talk about this HiSmile product I myself bought one. This kit costs $60.00. The kit includes the mouthguard, LED light, and 3 syringes of gel. You are to use half a syringe of gel per application, therefore the kit provides 6 uses. The directions HiSmile provides in order to get the results shown is to use the product 6 days in a row. Therefore that $60.00 spent on this product will be gone by the sixth day. In order to keep up with your white teeth you have to continue to by more syringes of gel. For 3 more syringes of gel it costs $25.00. You are suppose to use the product once a week after the first 6 consecutive days. This becomes extremely pricey. For some people $60.00 and then $25.00 every 6 weeks is a ridiculous amount to pay for whiter teeth.
In my opinion this product is worth every penny. I had decently white teeth, but I wanted them to be whiter. I was hearing all about this product so I bought it. After using the product my teeth became even more white. People other than myself noticed how much whiter my teeth had gotten. This product is pricey, but you can’t find a toothpaste that will whiten your teeth like this product does. Also paying for a dentist to whiten your teeth costs more money and takes a lot more time. Not only does it take more time and cost more, but you can’t do it in the comfort of your home. This product is worth every penny and the results exceeded my expectations.
I have used snow whitening kit& used HISmile. I like snow better easier to apply& more effective , snow takes 30 min but it is very worth it .
