About HiSmile

By HighYa Research Team
Updated on: Mar 28, 2018

You want a whiter smile, but your teeth and gums are too sensitive for hydrogen peroxide.

The good news is that HiSmile manufactures a line of peroxide-free teeth whitening products that use sodium bicarbonate instead, which can provide a pain-free alternative. No more irritation to your gums or mouth.

Despite its gentleness, the company claims their teeth whitening systems can deliver noticeable results in as little as 10 minutes by removing extrinsic (i.e., surface) stains, and can make your teeth up to eight shades whiter within six applications.

Add to this HiSmile’s 100 percent clinically proven results and patented mouth guard, and you’ve got a safe, easy, and effective way to whiten your teeth in the comfort of your own home.

But before you hand over any money, there are some things you need to know. First, we’ll talk about the price of their different products.

HiSmile Products, Pricing, & Refund Policy

Overall, HiSmile currently offers five different natural, vegan products, which come with a 30-day money back guarantee (from the date of purchase), if customers don’t achieve teeth that are at least two shades whiter. According to the company, here’s what you’ll have to do to request one:

  1. Take a clear photo of your teeth before using.
  2. Use exactly as instructed.
  3. Take a clear photo after you've completed all whitening applications.
  4. Send your before and after photos to the company, along with a photo of the used products.
  5. Once approved, your refund will be processed.

Peroxide Free Teeth Whitening Kit

HiSmile’s kit includes 3 x Teeth Whitening Gel syringes, 1 x Mouth Tray and LED Light, a Teeth Whitening Shade Guide, and a step-by-step Instruction Manual. Here’s how it works:

  1. Apply 1/4 of the gel to the face of the top of the mouth guard, and 1/4 of the gel to the face of the bottom of the mouth guard.
  2. Then, place the guard in your mouth and turn the LED light on. After 10 minutes, the light will turn itself off and beep.
  3. Afterward, rinse your mouth and mouth guard.

The kit will give you six applications (two applications per syringe). The company recommends using the gel every day (consecutively) for the first six applications, followed by one weekly application to maintain results.

HiSmile’s Whitening Kit is priced at $79.99 AUD, $59.99 USD, £49.99, €54.99.

If you’ve ordered HiSmile’s Whitening Kit previously and only need individual pieces, these are available for purchase as well:

Day & Night Toothpaste

The Day formula contains something called a Micro-Shield wax that promises to prevent stains from occurring, while the night toothpaste is said to use “charcoal and other natural ingredients to remove stains and detoxify the mouth.” Features a pleasant peppermint flavor.

Pricing: $19.99 AUD, $15.99 USD, £11.99, €13.99 (available on subscription for 30 percent off).

Teeth Whitening Gel Syringes

These use a blend of sodium bicarbonate and sodium chlorite to provide whitening, along with light activators like pomegranate, aloe vera, and chamomile, to help whiten up to eight shades in 10 minutes, without sensitivity. For use with HiSmile’s LED Light & Mouth Tray.

Three gel pens are priced at $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

Peroxide Free Teeth Whitening Pen

HiSmile’s Teeth Whitening Pen can be used for touch-ups when you’re on the go, and is also great for hard-to-reach areas. Contains the same peroxide-free formula found in the syringes.

Priced at $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

Coconut Whitening Mouthwash

Features sodium bicarbonate as its key whitening ingredient, along with coconut to extract toxins from your teeth and gums. Application only takes about two minutes.

Five coconut tubes and an instruction manual will cost you $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

How Do HiSmile’s Prices Compare to Other At-Home Whitening Kits?

Compared to some of the other teeth whitening products we’ve reviewed here at HighYa, including Whitening Coach, Action Pro White, and many others, HiSmile’s kit is about half the price.

However, the ASOTV whitening kit Dial-a-Smile comes in less than HiSmile, while other tray-based bleaching systems can be purchased locally for as little as $11.

Granted, all of these use hydrogen peroxide, while HiSmile uses sodium bicarbonate. But whether we’re talking about tooth sensitivity or whitening results, is there any difference between these two ingredients?

Hydrogen Peroxide vs. Sodium Bicarbonate

Most at-home teeth whitening kits use carbamide peroxide, which breaks down into hydrogen peroxide. In turn, this creates an oxidation reaction that dissolves stains and lifts them away.

The sodium bicarbonate (more commonly known as baking soda) in products like HiSmile, on the other hand, basically acts as a mild abrasive to scrub away stains from the surface of your teeth.

Comparing their effectiveness, carbamide/hydrogen peroxide is generally more effective at removing stains, especially those that may be older and located deeper within your teeth. However, it can cause some tooth and gum sensitivity, although this usually subsides quickly after treatment.

Overall, after undergoing exhaustive clinical testing, peroxide is considered very safe by the ADA for use in at-home whitening products.

Interestingly, since it’s an abrasive (however mild), extended use of sodium bicarbonate can lead to irreparable enamel damage. Sure, you might not experience any immediate tooth or gum sensitivity, but over the long term, using a baking soda-based whitening system can be much more harmful to your teeth than a peroxide-based one.

In all, this means that peroxide-based whitening systems will likely provide you with better, safer whitening results than ones like HiSmile—if you don’t suffer from tooth or gum sensitivity.

What are HiSmile’s customers saying about their results?

Are Customers Speaking Out About HiSmile?

Since writing our original article, more than 80 HighYa readers provided their feedback about HiSmile, giving the company an average rating of 3.3 stars. Common compliments referenced ease of use, effective results, and solid customer support, while complaints often related to no results. In most instances, a company representative responded directly to this feedback.

TheBlondePerfectionist.com noted that HiSmile was "incredibly easy" to use and that they experienced results by the second application. Ultimately, they were "blown away" by how effective it was.

Similarly, InsincerelyHer.com noted that HiSmile worked fast and gave them “super white” teeth in weeks.

PetiteAnchors didn't see much of a difference with HiSmile, and claimed that "it made no actual difference to my teeth colouring." Granted, the author noted that she had undergone a couple of professional whitening treatments in the past, as well as numerous at-home treatments, and concluded that her teeth simply couldn't get any whiter.

Now, let’s wrap everything up as neatly as the box HiSmile comes in.

Is HiSmile a Pain-Free Way to Whiten Your Teeth?

Can HiSmile provide you with a whiter smile, without sensitivity? With its baking soda-based whitening gel, it’s certainly possible.

Will it provide you with similar (or better) results than other peroxide-based at-home whitening kits? Again, it’s possible, although hydrogen peroxide is generally more effective at removing stains underneath your enamel, which could provide more shades of whitening.

Will HiSmile’s LED light provide any better or faster whitening results? Almost certainly not.

Given all of this, will HiSmile provide a solid value for the money? If tooth and gum sensitivity is your number one concern (and you’ve already tried a peroxide-based kit), then baking soda-based products might be your only option.

The catch here is that you could potentially achieve similar results using a DIY baking soda paste, which can be made for just a couple dollars. Or, you can purchase a tube of baking soda toothpaste from several different national companies for not much more.

Despite these concerns, the before and after pictures features on HiSmile’s Instagram page indicate that the company has hundreds of satisfied customers. Although due to the abrasive nature of the baking soda in HiSmile’s gel, we’re hoping they don’t continue using the product for too long, or they might permanently damage their enamel.

    Disgusting treatment of customers

    My delivery hadn't progressed for a week, so I emailed them. They told me I should call Australia Post. Australia Post tells me that HiSmile has only issued a manifest but didn't actually give them a physical parcel to send. So I email HiSmile asking them to follow up. They tell me to wait.

    So I wait. The delivery progressed as soon as I mentioned the issue to them. Then I email them asking for a resolution to my complaint, and why should I pay for delivery when they haven't delivered it on time, and I've had to spend time resolving their issue?

    They responded to tell me that I should visit nearby post offices to find my parcel. The delivery details clearly say it's in transit so why tell me to visit the post office? I have chronic health issues which make it difficult for me to leave the house and their treatment of me is plain cruel. They've not once offered to follow up on the whereabouts of my parcel or offered to treat me with any respect. It's one big cruel joke to them.

    I've paid for an item I haven't received, I've had to follow-up on the delivery that has never arrived, and they clearly get a rise out of torturing those with chronic health problems. Apparently, that's fun.

    I would be happy to share their email correspondence with the media. Not a good look.

    Bottom Line: No, I would not recommend this to a friend

    Horrible delivery

    • United Kingdom,
    • Nov 1, 2017
    • Verified Reviewer

    I have placed an order to HiSmile on the 16th of October 2017 and paid for next day delivery. It has been two whole weeks, and the customer team kept on saying that there has been a delay every single time I asked them. This is the worst experience I have had with any online purchase. The customer care replied as if they did not care about their customers. I am still waiting for my parcel.

    No refund as I haven't taken photos before treatment

    • London, England,
    • Sep 7, 2017
    • Verified Reviewer

    The treatment didn't work for me. I asked for a refund and it was denied as I have not taken pictures before starting the treatment. I am sorry, but I didn't know it was NOT going to work? They should mention it on the box or instructions. PLEASE BE AWARE before buying the product. I am very disappointed.

    No response and can't track

    • Faroe Island,
    • Sep 19, 2017
    • Verified Reviewer

    I saw HiSmile's products everywhere and thought that I would try it out. Everyone got good results and everything so it should work.

    I purchased it on the 14th of this month and got an email saying that the packed was being shipped and I could track it with a link in the email. Only to be thrown back onto my final order side to see a box where it said: "Direct Link tracking number: N/A." And there is no way for me to track my order.

    I thought that maybe something was wrong and emailed HiSmile about my problem tracking my order. I got an email back saying they had gotten my email and would be in touch soon.

    It has now been four days, and nothing has happened. I emailed them again today hoping for a response.

    Does anyone know anything about this?

    They steal your money and don't have enough courage to even talk to you about their mistakes. They take advantage of innocent people that come to their site to put money in their pockets and instead they rip it from your hands and give nothing in return.

    Absolutely appalling!

    No answer via email and no product received when paid for express shipping. HOWEVER, you have taken my money! If I do not hear back from this company, I will be reporting to Trading Standards and my bank.

      Company Response from HiSmile

      Hey Joelye,

      We are experiencing a high volume of orders from our Black Friday and Cyber Monday sales, so your order will take slightly longer to be dispatched, as I believe would have been stated in your confirmation email.

      Our customer care team have a higher than normal volume of customer inquiries at the moment from the sale period, so please allow at least 72 hours for a response.

      If you let me know the email address you emailed us from, I will make sure that you are responded to ASAP.

      Looking forward to hearing from you!

    HiSmile more like ByeSmile

    • Auckland, New Zealand,
    • Dec 1, 2017
    • Verified Reviewer

    I ordered the HiSmile during the Black Friday sale on the 26th of November and my order was not dispatched on the 30th, which was bizarre since I PAID for express shipping. And when I complained the sales associate on live chat named Ashton did not answer my question or help me and as a result, I return to my emails just to find that HiSmile had resent my confirmation and delayed the delivery by 4 days!

    This is unreasonable. I paid to have my product ASAP. I feel scammed and definitely would not recommend to anyone as I am waiting for my order. And I mentioned to the sales associate that I am unable to receive it after the 5th of December as I would be overseas, but I was willing to pay more, but instead she just returned with an automated response and resent my confirmation. This is unfair as I ordered based on the guarantee that I would have my order by the 5th the latest, not SHIPPED on the 5th.

    They use Black Friday as an excuse yet I order off websites in America on the same day, and my order is scheduled to arrive this week, and I didn't even have to to pay for express shipping!

      Hi Valentyn,

      As I'm sure you can understand the Black Friday/Cyber Monday 30% off sale our warehouse has been doing the best they can in dispatching all orders. I can see that Ashton has helped you change your shipping address so it reaches you while you are away for the holidays! If you have any further questions, please feel free to reach out to us via email and one of our customer care team members will respond ASAP.

    Avoid!

    I placed my order 13 days ago and it is still not dispatched! After numerous emails, I have asked for a refund as I fear that my item, which is a Christmas gift, will not be here on time!! I was told 7 days for a refund! This means I cannot replace the gift for another 7 days. They are quick to take your money but not give it back! I have pleaded with them in email and on Facebook and no one cares! I'm quite upset and feel like this is a scam.

      Hi Tammy,

      I can see that one of our customer care team members has processed a refund for you, which may take 2-5 business days to reach you. This is due to the bank holding the funds, which is out of our hands.

      Thank you and looking forward to hearing from you.

    Shipping fluke

    HiSmile seemed like a reputable company at first glance. Then, I ordered my package and was completely disappointed. I bought $9.99 shipping so it would arrive in 2-4 days, but they don't tell you it's on their terms. Still waiting for my package. I emailed and they told me to allow another 48 hours and they will not refund me for my shipping charge. That's not good, and I would not order from them again.
