Is this the best whitening system for you?

Are you thinking of using the HiSmile teeth whitening kit but want to read some HiSmile reviews first?

Well, we're here to help with a comprehensive examination of the HiSmile kit.

Keep reading to get answers to these questions and more:

  • Does HiSmile work?

  • How does it compare to other whitening kits?

We aim to take the confusion out of choosing the right solutions for a smile you love.

Is HiSmile safe?

Before we go any further with the review, let's talk about the most important thing—safety. The American Dental Association says that whitening, both in-office and at home can indeed be affective and safe. HiSmile guarantees that its kit is completely safe, even for those who suffer from sensitive teeth. The one risk that might occur is that since you apply the whitening gel directly into the tray, there could be some overflow when you put it in your mouth. This is a problem with whitening kits whose ingredients can cause burning and irritation to the gums. It's not clear if this is the case with HiSmile, but it's certainly worth considering.

HiSmile teeth whitening kit overview

HiSmile is an Australian company which was founded in 2014. Their teeth whitening kit and other products have gained great success across the globe, significantly helped by their strong social media marketing strategy.

One of the unique selling points of the HiSmile kit when it first hit the market was its 10-minute treatment time. Other kits are now available offering the same thing, although many alternatives still require 20-45 minutes of treatment per day. HiSmile guarantees at least two shades of whitening with a six-day treatment, meaning a total whitening time of just one hour. That's clearly appealing for anyone with a busy daily schedule.

HiSmile has a 4.5-star rating on Trustpilot at the time of writing, which is quite impressive, and their customer service gets a special mention. However, it seems that the majority of their 5,000+ reviews are the result of a ‘Free Starter Set for you and a friend' marketing promotion which began in late 2019. Customers who leave a HiSmile review here during the promotion are entered into a monthly prize draw. So, interpret that as you will.

You can't deny that there are thousands of positive HiSmile reviews out there, but you may also be wary of a product that is known for its paid celebrity endorsements.

You can read our detailed HiSmile review below, but here's a quick summary:

The HiSmile teeth whitening kit produces visible results for most people and comes with a money-back guarantee for anyone who doesn't achieve two shades of whitening (provided you follow their instructions). The gel formula protects against sensitivity and refills are easy to purchase. However, the kit doesn't present great value for money when compared to others on the market that offer similar results.

Our overall rating: ★★★☆☆ (3/5 stars)

Kit contents ★★★☆☆ (3/5 stars)

Here's what you get when you purchase a HiSmile whitening kit:

  • Fixed-shape mouth tray
  • Attachable LED light with 10-minute timer
  • 9ml of whitening gel (3 x 3ml syringes)
  • Instructions (on the bottom of the box)
  • Colour chart to measure results

It's nicely packaged in a sleek white box, but it feels a bit light on contents compared to some of its competitors – especially the quantity of gel you receive.

Other products available to purchase from HiSmile include:

  • Gel refills
  • Toothpaste
  • Whitening pen
  • Mouthwash
  • Breath spray

They also offer a subscription service, whereby you can have the gel refills, toothpaste or whitening pen automatically shipped to you every one, two or three months. There's a 15% saving on the regular price, and you can cancel any time. This could be useful if you want to top up your whitening results regularly without having to remember to order the products.

The following HiSmile review from a dentist shows what the kit contains and exactly how it works. The video is from February 2019 but note that the ingredients have changed since then.

Ingredients ★★★★☆ (4/5 stars)

What's in HiSmile whitening gel? Here's the full ingredient list:

Sorbitol, Water, Phthalimidoperoxycaproic acid, Propylene Glycol, Glycerin, Potassium Nitrate, Polyethylene Glycol-8, Hydroxyapatite, Sodium Carboxymethyl Cellulose, Hydroxyethyl Cellulose, Xanthan Gum, Peppermint Essence, Saccharin Sodium, Methylparaben, Sodium Bicarbonate, Aloe Leaf Extract, Chamomile Extract, Pomegranate Seed Extract, Propylparaben.

The key ingredients for the whitening process are:

  • Phthalimidoperoxycaproic acid (PAP): Recently added following a change in formula, this is the main bleaching agent which gets to work on the discolored molecules in your teeth.
  • Hydroxyapatite: A mineral naturally present in bones and tooth enamel which helps remineralize the tooth surface.
  • Potassium Nitrate: An ingredient used in dentistry, especially toothpastes, to prevent sensitivity. It works by blocking access to the nerves.

Are these ingredients safe for teeth whitening? The kit is manufactured in China and meets all regulations for this type of product in the US. However, we always recommend using products which are made in a country which itself has strict regulations, such as the US or Europe.

HiSmile says that users will not experience any sensitivity at all with this formula. It's a bold claim since some people have much more sensitive teeth than others.

Reviews reveal a mixed bag of feedback on the sensitivity issue. A few reviewers mention that they have experienced some sensitivity, especially when eating, but for most people, it wasn't enough to make them cut their treatment short. Others who were expecting sensitivity have had a completely pain-free process.

If you are concerned about sensitivity with teeth whitening, we mentioned the Snow whitening kit in the intro; they are known for their sensitive teeth formula. You can read more about the company here to find out if it's right for you.

Ease of use ★★★★★ (5/5 stars)

This kit is certainly easy to use. With a fixed shape mouth tray, there's no fiddly molding required. Just attach the light, insert the gel, and it's ready to go. The instructions are really clear, and you use about half a syringe of gel each time – 1/4 on the top and 1/4 on the bottom of the tray.

The short treatment time of just 10 minutes a day is definitely a benefit, too; many other kits on the market take 20-45 minutes. Although the mouthpiece is hands-free, so you can walk around and get on with other stuff while you're whitening your teeth, it still stops you from going out or having a conversation with anyone.

Some people also find they drool a lot while using these kits, so the shorter the treatment time, the better. Even if 10 minutes feels like too long for you, you only have to keep it up for six days.

HiSmile recommends using the kit after brushing your teeth at night. Rinse your mouth with water afterward to remove any leftover gel, and for best results, don't eat anything until the next morning.

Results ★★★☆☆ (3/5 stars)

HiSmile says you'll see teeth a minimum of two shades whiter after using their kit. You measure this using the color chart provided in the kit. The more stained your teeth are to begin with, the more noticeable your results are likely to be.

Do be wary of HiSmile ‘before and after' photos posted to social media where the two images are taken in different lights. Look at the lips and skin as well as the teeth to judge whether the tone of the photo enhances the results. For example, the teeth in the image here are certainly whiter, but so is the person's face.

Most at-home whitening kits will not be able to produce the same results as laser whitening at a dentist, but you should get slightly whiter teeth if you use this kit as instructed.

We say most kits, because the kit we mentioned in the intro, Snow, can yield professional results for the price of an at-home kit.

To find out more about what customers think of HiSmile, here's a selection of comments from HiSmile reviews on Trustpilot:

“I have used the starter kit for 6 days in a row like the website said to, I haven’t seen a big change but there is a change!”

“Was highly sceptical of this product before purchasing, but after using the hi smile kit around a week I am definitely noticing some great results.”

“The kit has only helped a tiny bit, not as good as I hoped, going off the pictures I thought would make my teeth a lot whiter as it shows however hasn’t, but it is easy to use and pain free.”

“So far so good! only been using for a couple days but i can already see a difference.”

Some people find that they needed to continue for another six days, using refills, to achieve the results they want. The company recommends using the kit once every two weeks to maintain results.

HiSmile does offer a 30-day money-back guarantee if your teeth haven't improved by at least two shades after six days' consecutive use. To be eligible for this, you must take before and after photos (timestamped) and email these, along with the evidence you have used the kit, to their customer service department.

Make sure you take a ‘before' photo so that, in the event you're not satisfied, you'll be able to make a claim.

Price ★★☆☆☆ (2/5 stars)

The HiSmile kit costs $59.99 in the US, which is certainly much less than a visit to the dentist for professional whitening, but then at the dentist, you're paying for much better results, too.

Given that you only get enough gel for six days of treatment, and refills work out at around $4 per application, the kit doesn't present great value for money – even if you are seeing good results.

HiSmile discount codes are often available, so it's worth checking for promos before you buy.

If you change your mind after purchasing, HiSmile offers a 30-day returns policy, but will only refund products that are unopened, unused, and still in sealed packaging. Minus any postage costs. Plus, you must email for pre-approval of the return, package it correctly, and return it at your own cost with a tracked delivery service.

Alternatives to HiSmile in the US

There's a ton of teeth whitening kits out there, and it seems like the choice is changing all the time. So if you haven't been won over by HiSmile reviews, what are your other options?

Our top pick for 2020 is Snow Teeth Whitening. Snow costs more than HiSmile, but the value that you receive for the price actually works out to be much better, since with Snow, you get a whole year's worth of treatments for the price.

Snow is another LED whitening kit that you only have to use for nine minutes per day. You also have the option to use an app with the whitening system to control how white you want your teeth to get, and at what pace. And just like with HiSmile, with Snow you can buy refills so you never actually have to pay all over again for the LED mouthpiece. We encourage you to find out more about why Snow is being considered the “Apple of teeth whitening.”

You can have a look at the table below for a summary of the differences between Snow and HiSmile.

Snow HiSmile
Treatment time 9–30 minutes 10 minutes
Treatment duration 21 days 6 days
Main whitening ingredient Hydrogen peroxide, Carbamide peroxide Phthalimidoperoxycaproic acid (PAP)
Made in US China
Type of mouth tray LED mouth tray. Gel is applied directly to teeth to prevent overflowing and damage to gums. Fixed shape, external LED. Gel is inserted directly into tray. This can cause the gel to overflow and damage gums.
Effects last At least 1 year Much less than a year

Conclusion

So, does HiSmile work? Yes, for most people, but set yourself realistic expectations about the results. They guarantee two shades brighter, and if that's ok with you, by all means, give it a go.

Their specially formulated gel is supposed to be very gentle on teeth, but some users still experience sensitivity.

The main downside of HiSmile is that you really aren't getting a lot of value for the price. The gel refills aren't cheap either, so be prepared to keep paying this price if you want to maintain your whiter smile. If you're looking for a whitening kit that offers a better value for the price, and more dramatic results, you may want to consider Snow.

We do like the fact that the company offers a selection of oral care products and encourages users to follow good habits for oral health – not just whiter teeth. That's definitely something we can get behind.
