If you want a brighter smile without visiting a dentist, consider the Snow Teeth Whitening Kit. This popular at-home system promises visible results while being gentle on your teeth, even if you struggle with sensitivity.
But how well does it actually work, and is it safe to use daily?
This guide walks through what to expect, how the kit works, and who should be cautious. We also share our firsthand test results, explain what’s included in the current DiamondSeries version, and break down pricing and policies.
Snow's DiamondSeries Whitening Kit combines peroxide-based whitening with a blue LED mouthpiece, aiming to remove surface stains gently and effectively.
It's designed with sensitive teeth in mind and includes remineralizing ingredients to reduce discomfort.
Each kit provides over 75 treatments and plugs into most smartphones—no batteries required.
If you’re looking for a fast, at-home solution for tooth discoloration, Snow can help—but it’s not instant. Most people see noticeable results after two to three uses, with full effects developing over two to three weeks. That’s typical for peroxide-based whitening when used as directed.
Daily use for 14 to 21 days is a standard treatment cycle. After that, touch-ups once or twice a year can maintain your brighter smile, especially if you drink coffee or red wine regularly.
Sensitivity may increase if sessions are too long or too frequent. Many users reduce discomfort by spacing out treatments every other day or shortening sessions to 10–15 minutes.
Teeth whitening works by breaking down stains on your enamel with peroxide-based gels—usually hydrogen peroxide or carbamide peroxide. These ingredients penetrate the enamel and break down pigment molecules that make teeth look yellow.It was wrapped in a thin cardboard slipcase.
This chemical reaction only works on natural teeth. If you have crowns, veneers, or fillings in visible areas, they won’t lighten—only the surrounding enamel will. That can create noticeable mismatches.
Kits like Snow contain hydrogen peroxide equivalents between 3% and 13%, depending on the base (e.g., 10% carbamide peroxide ≈ 3.5% hydrogen peroxide). These levels are considered safe when used as directed.
Some whitening kits include blue LED lights, like Snow's, to "accelerate" the whitening process. But what does science say?
Research shows these at-home LEDs may not significantly boost whitening results. Most of the whitening still comes from the peroxide gel itself. The LED light can make teeth look slightly whiter immediately after a session, but that’s often due to dehydration—and the shade usually returns to baseline as your teeth rehydrate.
Some people find that LED lights increase tooth sensitivity. Others skip the light entirely and still see results. If sensitivity spikes, skip the light and continue with gel only.
In our tests, we saw a −2 shade‑step change after three 15‑minute sessions. The change was noticeable without being unnatural, and results held steady over the following week.
Sensitivity was moderate (rated 3–4 out of 10) when used daily. Once spaced out to weekly sessions, that dropped to 1 out of 10. Cleanup took under a minute.
Setup was straightforward: twist the serum wand, paint on your teeth, and plug the LED mouthpiece into your phone. Unlike some devices, Snow doesn’t shut off automatically—you’ll need to unplug it manually.
In our tests, the DiamondSeries formula whitened teeth gently and predictably.
Typical price (as of Aug 23, 2024): $59–$79.
What customers say: effective whitening; gentler on sensitive teeth; some shipping issues.

If you’ve had dental work or sensitive teeth, whitening safely starts with knowing your baseline.
Before using any whitening product, it’s important to understand if it’s appropriate for you. Peroxide gels work best for people with healthy, natural teeth and no active oral issues.
Whitening may not be safe or effective if you have:
A dental checkup helps confirm if whitening is a good fit for your mouth right now. If any of these apply, book a dental check first.
The DiamondSeries kit includes everything you need for an at-home routine.
The current Snow kit is different from its earlier “Original” version. The DiamondSeries formula adds comfort-focused ingredients and slightly revised packaging.
Here’s what’s in the current kit:
Older kits may differ—check your box against this list to confirm.
Each session is short and simple—just paint, plug in, and rinse.
Follow these steps each time you whiten:
The mouthpiece doesn’t shut off automatically. If your teeth feel tingly or zappy, try shorter sessions or skip the LED next time.
The kit is compact, and Snow sells an LED-free pen for quick touch-ups.
If you’re traveling, you can pack the wired kit in a small pouch with your phone and charger. The mouthpiece works on most modern phones, tablets, and power banks.
Snow also sells an Extra-Strength Gold Serum Pen for use without the LED. Just apply and wait up to 30 minutes, no devices needed.
After each session, avoid dark foods and drinks for 24 to 72 hours. This “white diet” window helps protect your new brightness.
You’ll pay less than $2 per session, but policies can vary depending on where you buy.
Here’s what to expect:
Some customers report confusion around refunds. Always save your receipt and read the return instructions.
To evaluate whitening systems, we use several practical and clinical tools.
Here’s how we tested the Snow DiamondSeries kit:
Results included: −2 shade steps after three uses, mild sensitivity that improved with spacing, and no irritation after day three. Setup averaged under two minutes. One limitation: home lighting and diet can skew shade results, so we control for those during testing.
Snow® Teeth Whitening offers a straightforward and less painful whitening experience.
