    Hydroxyapatite

    The breakthrough mineral originally developed by NASA to protect astronauts’ teeth in space and widely used in Japan as a gold standard for oral care. Clinically shown to help rebuild and strengthen enamel, restoring your smile’s natural brilliance while keeping it safe and strong.

    Carbamide & Hydrogen Peroxide

    A powerful duo of whitening agents that help lift surface stains for faster results.

    Potassium Nitrate

    A natural desensitizing agent that fights tooth sensitivity while you whiten.

    Glycerin & Xylitol

    Helps moisturize and maintain a healthier microbiome.

    Key Ingredients
    Image Steps
    The Science
    A powerhouse of three clinically trusted ingredients penetrate enamel for a whiter smile with virtually zero sensitivity.

    Carbamide and Hydrogen Peroxide break down stain molecules to reveal your significantly whiter smile fast while Potassium Nitrate desensitizes the nerves within your teeth so you feel less sensitivity while eating or drinking hot, cold, or sweet foods and drinks.

    Additionally, we’ve infused this serum with Hydroxyapatite – a naturally occurring mineral that makes up 97% of your tooth enamel and 70% of your dentin. This vital mineral supports your teeth enamel while you whiten.

    Better than the dentist
    I’ve used trays  with whitening tubes from the dentist and they never lightened my teeth. I use it only once a week to maintain the new light color and no burning peroxide!

    Take 10-20 years off
    I think it is amazing.The whiteness of your teeth can take 10-20 years off your appearance. I also use the whitening powder daily with my toothpaste.

    Teeth are visibly whiter with no pain.
    I have the most sensitive teeth and gums. I tried all the whitening toothpastes, serums, oil pulling and “sensitive teeth'' products that would leave me in pain for days.

    Questions

    How is Snow Diamond Whitening Serum different?

    Snow Diamond Whitening Serum is a 3-in-1 formula that whitens fast while fighting sensitivity and helping repair and strengthen your enamel. While most whitening serum focuses only on whitening your teeth, our better for you formula whitens while promoting thriving oral health.

    How quickly will this whiten my smile?

    With the combination of Carbamide and Hydrogen peroxide, this serum is powerful enough to dramatically whiten your smile after just one use (results will vary person to person)

    Can I use the serum on its own?

    Yes you can! This serum can be used on its own, or you can use it with our Accelerating LED Mouthpiece for fastest results.

    Will this serum hurt my teeth?

    This serum is formulated with both Nano-Hydroxyapatite and Potassium Nitrate. Nano-Hydroxyapatite helps repair and remineralize your teeth while Potassium Nitrate actively fights sensitivity while you whiten. Most people don’t experience any sensitivity with this serum!

    What does this serum taste like?

    The serum is formulated with Mentha Piperita (Peppermint) for a refreshing flavor as you whiten your teeth!

      Extremely satisfied customer

      I purchased the 1-yr supply of SNOW teeth whitening wands after having recently purchased the kit. I am beyond pleased with the results I’ve seen for myself within 3.5 weeks use and only 3 times each week. The simplicity of the kit made it super convenient and the best part is the sensitivity free formula! I am super excited to see the continuing results for the YEAR to follow with this recent purchase! You won’t regret this, and best of all the Affirm payment option was the cherry on top!

      So shocked!!

      I can’t believe how quickly it worked. I thought maybe it would whiten them a little but my teeth after just a week are at least 5-7 shades lighter. It’s insane.
