Hismile Reviews 2021

What is Hismile?

Hismile is an Australian-based brand of oral care products, specifically peroxide-free whitening. The products are widely used in the UK but are growing in popularity in other countries. 

Hismile uses a proprietary PAP+ formula to whiten teeth. The hero ingredient, phthalimido peroxy caproic acid (PAP), claims to whiten teeth quickly and effectively without irritation or sensitivity.⁸ 

The Hismile formula also has other supporting ingredients that enhance the health of your teeth. They include hydroxyapatite and potassium citrate.

Additionally, Hismile has an on-site facility (Hismile Research Centre) for product testing and formulation. This allows them to work with leading dentists and product experts to shape the future of teeth whitening.

Hismile sells a few different oral care products, including a whitening kit, strips, toothpaste, and mouthwash. 

Hismile PAP+ Teeth Whitening Kit™ Review

Hismile launched its first teeth whitening kit in 2014. They sent kits to hundreds of people to try out during this time — from video bloggers to celebrities like Kylie Jenner.

The overall verdict was positive. Now, Hismile has a global community of over 3 million customers. 

Hismile’s whitening formula is 100% peroxide-free. Peroxide is the main active ingredient in most whitening products. It has been extensively studied as an effective whitening agent.^{1, 2, 3}

However, Hismile’s at-home teeth whitening treatment claims to be just as effective as peroxide without the unpleasant side effects. Peroxide as a bleaching agent can cause sensitivity, gum irritation, and the demineralization of teeth.^{1, 4, 5}

Hismile's teeth whitening kit uses three powerful, enamel-safe ingredients to provide instant results without any sensitivity:

1. Phthalimidoperoxycaproicacid (PAP) is clinically proven to whiten teeth without sensitivity or gum irritation.
2. Hydroxyapatite (nHAp) rebuilds the protective layer of teeth and replaces lost minerals.
3. Potassium citrate helps relieve pre-existing sensitivity and provides long-term protection.

How to Use Hismile Teeth Whitening Kit

The Hismile PAP+ Teeth Whitening Kit is very easy to use, especially compared to similar products on the market. The process takes a total of 10 minutes a day (vs. up to 45 minutes for other brands). 

The kit includes an LED device with a built-in timer, a universal mouth tray, six whitening pods, and a shade guide.

To use the kit, follow these simple steps:

1. First, brush your teeth for two minutes before beginning the whitening treatment. 
2. Open the back cover of the device and remove the batteries. Pull out the plastic tab and then reinsert the batteries to activate the device. 
3. Attach the mouth tray to the LED device. 
4. Open one of the PAP+ Teeth Whitening Pods. Each pod contains enough gel for one full whitening treatment. 
5. Apply half of the PAP+ gel to the top of the mouth tray. Repeat this step for the bottom of the tray.
6. Power on the LED device by pressing the button on the device. It’s hands-free, so you can walk around freely.
7. Whiten for 10 minutes. The device will automatically shut off.
8. Spit out any excess gel and rinse your mouth with water. 
9. Results are noticeable after one to two treatments. Use all six treatments for the best results. 

How Quickly Will You See Results? 

Some customers see results after one to two treatments. Results vary depending on your level of tooth discoloration. 

Hismile’s whitening kit comes with six pods. One full pod is used per treatment. 

You’ll likely notice the full benefits after you complete the full treatment course. This takes about a week (six treatments) if you do them back-to-back.

How Long Does Hismile Last? 

Hismile claims the whitening results should last between two weeks and three months. 

How long your teeth stay white depends on lifestyle and diet habits. For example, if you drink a lot of coffee, the results won’t last as long. You’ll need to whiten more consistently. 

Other staining foods include dark-colored berries, red wine, soda, curry powder, and tomato sauce. Cigarette smoke also discolors teeth. 

Does Hismile Actually Work?

Based on customer reviews, Hismile seems to be a relatively effective whitening product. Many customers mention instant results, while others don’t see results until after six treatments. 

There are also some negative reviews (as with any product). Some customers say the products don’t work at all. However, this could be due to deep staining, which often requires professional whitening in a dental office.

Based on our research and personal testing, Hismile’s products do work in most cases. Keep reading below to learn more about the effectiveness of Hismile whitening. 

My Experience Using Hismile Teeth Whitening Kit

I personally tested Hismile’s PAP+ Teeth Whitening Kit™. The main benefit of this kit is that it is very easy to use. It also doesn’t irritate your gums, cheeks, or tongue.

With other whitening kits, I’ve noticed they can cause irritation during and after treatment. This is especially true if the product has a high concentration of peroxide. But since Hismile doesn’t use peroxide, this wasn’t an issue. 

Another benefit of Hismile is the quick treatment time. You only have to use the kit for 10 minutes a day. Other leading brands typically require 30 to 45 minutes of whitening per session. I’ve found this to be inconvenient and it often makes the process messier. 

Lastly, in terms of results, I noticed minor changes in tooth color after just one 10-minute session. The changes weren’t drastic, but they were noticeable. I also experienced zero sensitivity after the first use. 

Note: My teeth were already fairly white to begin with. I don’t have deep-set tooth discoloration.

If you are looking for a sensitivity-free treatment with quick results, Hismile is worth checking out.

Why is Hismile Peroxide-Free? 

Hismile products are peroxide-free for a few reasons:

1. Peroxide causes free radical oxidation that leads to unpleasant side effects. These include tooth sensitivity and gum irritation.^{1, 4} But most adverse effects are easily reversible.⁶ 
2. Peroxide dehydrates your teeth, which is what causes the sensitivity.⁷ Enamel dehydration produces a temporary, visible tooth shade reduction.⁷ 
3. Peroxide may demineralize teeth (i.e., the loss of important minerals to keep teeth strong and healthy). However, there are mixed studies about whether this is true. One study found that hydrogen peroxide whitening did not affect mineral loss.⁶ Another study concluded that high peroxide concentrations can lead to demineralization.⁵ 

What’s the Science Behind PAP?

Hismile’s initial goal was to develop a whitening formula that provides peroxide-level whitening without the side effects. This is how they discovered PAP and created the PAP+ formulation.

According to Hismile, the PAP+ formula combines expert-level whitening with fast and effective results.

Unlike peroxide, PAP doesn’t release free radicals or dehydrate your teeth. This means that the discoloration molecules are broken down safely, without the risk of sensitivity, damage, or irritation.⁸

PAP is a highly reactive whitening agent that lifts stains by targeting internal and external discoloration. Due to its potency, it can whiten teeth after just one to two treatments. Results vary.

An independent study found that PAP had immediate whitening effects after a single-use treatment.¹⁰

The PAP+ formula also contains hydroxyapatite (nHAp). Some research shows that hydroxyapatite is superior to conventional fluoride for cavity prevention.⁹ 

nHa also mimics your natural tooth enamel (provides protection) and replaces lost minerals.

Lastly, the PAP+ formulation contains the active ingredient potassium citrate. This ingredient helps prevent and reduce sensitivity. One study found that toothpastes containing potassium citrate are effective in reducing dentin hypersensitivity.¹¹

Is PAP Safe? What are the Risks?

Based on our research, Hismile’s PAP+ whitening formula seems to be safe. Most customers are satisfied with their whitening results and don’t experience adverse reactions. 

Note: PAP is a newer ingredient that can be found in select whitening products. It has not been extensively studied. Because of this, some dental experts advise against it.¹² 

For example, Dr. Mark Burhenne, DDS ‘recommends waiting for further studies to be conducted on PAP before jumping on the bandwagon.’ He says overexposure to hydrogen peroxide and PAP can increase tooth sensitivity.¹² But this has not been proven. 

Other Hismile Products 

The Hismile PAP+ Teeth Whitening Kit is the brand’s #1 bestseller. It is the first product they created in 2014.  

Since then, they have developed more oral care and whitening products. Here is a short overview:

• PAP+ Whitening Strips™ use the same formula as the teeth whitening kit but with added convenience. The strips offer effective peroxide-free whitening on the go. 
• PAP+ Toothpaste™ is another convenient whitening treatment that can be used daily or when needed. The toothpaste is designed to provide gradual whitening results. It also includes ingredients that protect your teeth from damage and decay. I personally tested this product.
• PAP+ Mouthwash™ comes in a small, concentrated bottle. All you have to do is mix a dropper full with 15ml of water before use. It is also small enough to bring in a carry-on bag. I personally tested this product as well.
• Day & Night Toothpaste can be used for everyday cleaning. They are not whitening products. The Day Toothpaste features a protective micro-shield wax that protects your teeth from harmful bacteria. The Night Toothpaste contains gentle abrasive ingredients to help prevent cavities while you sleep.
• V34 Colour Corrector neutralizes yellow undertones and brightens dull white teeth.
• NHpro Enamel Care targets enamel remineralization and manages sensitivity.
