How Does it Work?

HiSmile is a line of teeth whitening products for home use. Let’s take a look at how it works. 

The HiSmile PAP+ Teeth Whitening Kit comes with six applications. To get the best results, you’ll need to use the kit daily for six days. 

To use the HiSmile Teeth Whitening Kit, just follow these instructions:

First, brush your teeth gently to be sure your teeth are clean of bacteria that could get in the way of your teeth whitening experience. Rinse your mouth carefully afterward, being sure no toothpaste residue is left behind. 

Be sure the LED-powered mouthpiece is fully charged. Then fill the mouthpiece with the whitening gel. Place the mouthpiece in your mouth and turn on the LED light.

Wait ten minutes while HiSmile whitens your teeth. The light will shut off automatically when time is up.

Remove the mouthpiece and rinse your mouth out using warm water. 

It’s recommended that users maintain their results by using the whitening kit once a week for two months. HiSmile sells PAP+ whitening gel refill pods to restock your teeth whitening kit. 

Other HiSmile products include PAP+ toothpaste, PAP+ mouthwash, and day and night toothpaste for daily use. 

What Sets HiSmile Apart?

What sets HiSmile apart from other home whitening products is its unique formulation as well as the research that went into developing its product line. Most teeth whitening treatments use peroxide, which releases free radicals. Free radicals are likely to cause side effects like sensitivity, gum irritation, and demineralization. 

HiSmile uses PAP+, their nickname for Phthalimidoperoxycaproic Acid, a whitening agent that effectively breaks down stains and lightens the appearance of teeth without releasing free radicals. PAP+ eliminates the risk of sensitivity, pain, or damage, making it a safer choice for whitening teeth. 

While peroxide-based formulas may weaken tooth enamel, HiSmile’s other active ingredients, Hydroxyapatite and Potassium Citrate, protect and strengthen tooth enamel, replace lost minerals from the tooth surface, and relieve pre-existing sensitivity. 

HiSmile promises no sensitivity during or after use of their products. Their formula contains no alcohol, parabens, SLSs, or PEGs. It’s also vegan-friendly. HiSmile’s mouth tray uses LED light, which intensifies and speeds up the whitening process.

“As a coffee drinker, I was super excited to try this teeth whitening kit and I was blown away! The LED device is super easy to use and features a timer so you can pop it in and do something while it works its magic. The formulation is also super gentle, non-sensitizing or irritating, and washes out easily. By the end of the 6 pods, I could see at least 2 shades’ improvement. Really enjoyed using this!” - Linh Tran, Australia, Apr 29, 2021

“Such an easy and convenient way to whiten your teeth at home. The formula and method of use are foolproof! My teeth are instantly whiter and I find that the new formula is much more sensitivity-considerate.” - Teresa, California, Apr 21, 2021

Bottom Line

HiSmile is an easy-to-use teeth whitening product line that uses a whitening agent called PAP+. PAP+ is unique in that it doesn’t contain peroxide, so HiSmile doesn’t cause the tooth sensitivity many home whitening kits are known for. The HiSmile kit takes only ten minutes a day to use because of its LED light technology. A mouthwash and toothpastes are also available.

Most users were impressed with the results they got from HiSmile and considered the kit worth it. While it may not make your teeth a full eight shades lighter, you’ll probably experience a noticeable difference. HiSmile isn’t cheap, but for those who prefer not to use peroxide on their teeth, it’s a great option.
