What Does SNOW’s At-Home Teeth Whitening Kit Include?

The at-home SNOW DiamondSeries Teeth Whitening Kit comes with:

  • 1 Diamond teeth whitening serum (2 ml)
  • 1 LED whitening device
  • Teeth shade guide

There is the option to upgrade to the three serums in a value pack for cost savings.

Diamond Whitening Serum

The special teeth whitening serum contains the whitening agents carbamide peroxide (CP) and hydrogen peroxide (HP). While CP penetrates the enamel to break down surface and deep stains, HP is a stain remover known for use in professional whitening.

Along with those two active whitening ingredients, the vegan serum also has:

  • Hydroxyapatite – This mineral helps repair tooth enamel
  • Potassium Nitrate – Eases sensitivity by calming dental nerves

There are other ingredients like glycerin, peppermint oil, and carbomer, which are mainly for consistency, taste, and application.

Accelerating LED Mouthpiece

The DiamondSeries Kit works via innovative LED light therapy. The mouthpiece uses the same LED technology as many dental offices to whiten teeth fast, per SNOW’s site. The mouthpiece has four adapters for USB, Android, iOS, and Type-C, so it fits into a range of devices and is travel-friendly.

Using blue light, the mouthpiece activates CP and HP for stain removal. Hydroxyapatite and potassium nitrate offer enamel repair and sensitivity support during whitening.

Teeth Shade Guide

The included teeth shade guide helps you track whitening progress, with up to 25 treatments per kit. The shades range from the brightest (1) to deeply stained (16). Starting with a baseline by matching your smile to a shade on the visual guide and marking it, then checking occasionally to see shifts in whitening can help track improvement.

Price

While not the cheapest, SNOW’s DiamondSeries Teeth Whitening Kit offers up to 25 days’ worth of sessions and is more affordable than a professional whitening treatment. Choose from a one-time kit or a monthly subscription; we like that you can customize it based on your needs. SNOW has online-only promos from time to time for money savings. Adding to the kit’s value is the money-back guarantee and long warranty.

SNOW DiamondSeries Teeth Whitening Kit: Pros and Any Drawbacks

Does this kit match your goals and offer what you expect? Understanding the benefits and any limitations can help you decide.

Bestseller

The DiamondSeries Teeth Whitening Kit has over 5,600 five-star reviews on SNOW’s website. It is a bestseller in The SNOW product lineup, a collection of popular products with over 200 million treatments sold, per its website. That speaks to the brand’s trustworthy reputation online. SNOW’s website highlights the formula as award-winning and the LED mouthpiece as having award-winning technology.

Dentist Created

The creator of the SNOW product line is Dr. Brian Harris, a leading cosmetic dentist in the US. Some people find it reassuring that a dental professional has helped develop the kit, given they know tooth anatomy and enamel health well.

Ease of Use

This kit is designed for adults ages 18 years and up. After brushing, the next step is painting the white serum directly on the teeth. Then, wear the light tray as per the product directions. Sessions range from 9–30 minutes, once a day. The short, once-a-day application fits many lifestyles, including busy professionals. Unlike some traditional methods, it is not messy; there’s no dripping.

Professional-Level Whitening

We like that the kit combines advanced tech and a science-backed approach with its simple application. The LED technology is the same as used in many dental offices to accelerate the whitening process and increases the opportunity for professional-looking results at home. The blue light activates the whitening agents in the serum, potentially leading to a brighter smile over time.

Timeline and Potential Outcomes

The one Diamond serum included in the SNOW kit is designed to last up to 25 treatments or a month’s supply. An affordable add-on is a three-serum value pack.

Among the words that buyers online use to describe their teeth using the SNOW DiamondSeries Kit are “whiter” and “shining.” While we cannot guarantee results, buyers’ feedback can offer peace of mind, including those who write that their teeth have gotten one or more shades whiter with regular use.

While whitening may happen upon first use for some people, it is intended to be a multi-use system. As with most things, that will suit some people but not others. “Brighter, longer-lasting results” come from the unique LED technology that helps the Diamond whitening serum penetrate the teeth deeply, as per SNOW’s website. Factors affecting how long results last include consuming foods and drinks that commonly stain teeth.

Enamel Repair

Unique to the SNOW DiamondSeries Kit is the hydroxyapatite in the serum. This mineral can help rebuild and reinforce enamel while whitening. That makes it appealing to those who worry about worn enamel, are looking for a gentler approach, or are considering whitening over a long period.

Addresses Sensitivity

The SNOW serum contains potassium nitrate, which can help calm dental nerves, and LED-activated peroxide for whitening with less discomfort. Several buyers note in their web reviews that they did not experience sensitivity post-use.

Also, the included hydroxyapatite helps block pain signals from exposed dentin in some users, a common cause of sensitivity. Those who might otherwise avoid an at-home whitening kit because of naturally thinner enamel or discomfort from other products might consider this one.

Staining

Tooth staining leaves some people feeling self-conscious. The serum’s carbamide and hydrogen peroxides may help break down surface stains, with the LED light activating the whitening agents. While that may improve some surface stains, gray-colored discoloration is typically more difficult for at-home kits to treat than yellow or brown stains. Very deep stains may require professional whitening or another solution recommended by your dentist.

What Else to Know about SNOW’s DiamondSeries Kit

Adding to the value of this DiamondSeries Kit is the included guarantee and warranty. It also is free of gluten and certain other ingredients.

Guarantee

SNOW’s 30-day Money Back Guarantee that comes with this kit shows the brand’s confidence in the quality of its product.

This protection shows brand confidence.

Cleaner Ingredients and Cruelty-Free

The kit focuses on cleaner ingredients. It is free of gluten, sugar, sulfate, fluoride, parabens, SLS (sodium lauryl sulfate), and alcohol. That makes for a gentler formula without several harsh additives commonly found in other teeth whitening products.

Plus, being cruelty-free and vegan means no animal-testing and no animal-derived ingredients. That is important to those who prioritize cruelty-free and vegan products.

Concluding SNOW’s Teeth Whitening Kit Review

The SNOW DiamondSeries Teeth Whitening Kit with Hydroxyapatite and Potassium Nitrate is a dentist-developed, at-home option for whitening and more. It combines advanced LED technology with whitening agents carbamide peroxide and hydrogen peroxide, plus enamel-supporting hydroxyapatite and potassium nitrate for sensitivity relief. While the kit does not fit every budget, it offers the potential for more than whitening alone for those who want to try it.

This SNOW kit also has a vegan, cruelty-free formula with cleaner ingredients, appealing to those who want a convenient kit without several harsh ingredients and less chance of discomfort. The kit may suit certain adults over 18 with sensitivity concerns, thin enamel, or those who want to try a convenient best-selling whitening option in short at-home sessions. With over 5,000 five-star reviews, a 30-day guarantee, and a two-year warranty, SNOW’s DiamondSeries Teeth Whitening Kit with Hydroxyapatite and Potassium Nitrate has a lot in its favor.
