CONCERNS ADDRESSED • Dull Teeth, Visible Stains, Yellow Teeth, Weakened Enamel

Certain bacteria known as chromogenic bacteria naturally develop in the mouth. They produce pigments responsible for dullness and surface stains on teeth, while promoting plaque buildup.

Over time, or following chemical whitening treatments, enamel can lose its natural shine and become more fragile.

KEY ACTIVE INGREDIENTS • Enzyme-Biotic Complex, Mineral Whitener (hydroxyapatite)

The Enzyme-Biotic Complex
A balanced oral microbiome is essential for healthy, bright teeth. Enriched with pomegranate enzymes and whitening minerals, our Enzyme-Biotic Complex targets stain-causing bacteria for naturally bright, long-lasting teeth. Scientifically tested.

Mineral whitener: Hydroxyapatite
Naturally derived and concentrated at 5%, it remineralises enamel, smooths its surface, and enhances its shine—without abrasion. It also strengthens the enamel while reducing its sensitivity.

Prebiotics
Alpha-glucan oligosaccharides feed the good bacteria in the oral microbiome and reinforce the natural microbial barrier, promoting a balanced and healthy oral ecosystem.

RESULTS • +42% whiteness, reduced stains

A whiter smile while respecting the enamel. Coloured stains fade away progressively, teeth appear more radiant and bright, without becoming sensitive.
After a professional peroxide whitening treatment, helps teeth stay whiter for longer while restoring enamel.

    I recommend 200%!

    I ordered the night whitening kit and have been using it for 1 month now. Results appeared after 2 weeks and it keeps improving while remaining completely natural!

  • Martine H Verified review

    Magic serum.

    I've been using the whitening serum regularly for 3 weeks and I can see a difference in the whiteness of my teeth. But the most surprising thing so far is the enamel radiance. Truly impressive!

  • V.M Verified review

    Fabulous serum.

    This is the second bottle of serum I've used. Tea and coffee stains are no longer present on my teeth. The color of my teeth has been naturally brightened. The serum is effective and above all is not abrasive — perfect for me as I have sensitive teeth.

The Enzyme-Biotic Complex

Whiteness Technology:
Anti-stains

  • A natural complex of pomegranate enzymes and hydroxyapatite, enriched with prebiotics. It brings back the teeth’s natural whiteness and reduces bacteria responsible for dental plaque and stains, while respecting the balance of the oral microbiota.

  • Pigment-producing bacteria cling to enamel and cause stains, especially after chemical whitening when the enamel is more vulnerable. This technology fights against their proliferation and helps preserve the enamel’s natural whiteness.

  • A progressive whitening process that respects the mouth’s natural balance. Peroxide-free and non-abrasive, it helps repairing and strengthen the weakened enamel.

Great, already a difference after a few days

Lovely products!

I bought several products, including this one, the whitening toothpaste, the purifying spray and the lip care. It was their story, their appearance on the show and their Yuka ratings that convinced me. For this serum I don't have enough perspective yet, but it's very easy to use and doesn't take much time to add to your evening routine. The toothpaste is good and effective, the spray really freshens your breath nicely and the lip care is great! My lips are much nicer and well moisturized.

A ritual that transforms my smile!

Since I started using The Smilist products, my teeth are getting healthier and whiter. I see a real difference every day, not only in how bright my smile is, but also in how clean it feels. Even my tongue is cleaner and fresher, which gives a pleasant lightness in the mouth. A simple gesture that's become a must-have in my routine! An essential ritual now.

Effective and gentle

My husband, a big coffee drinker, is very satisfied with the result. For me it's less obvious but I do see a difference. Having sensitive teeth and gums, I'm very afraid to get my teeth whitened at my dentist's, even though she offers a gradual treatment over several weeks. On top of that, she charges €500 per person; I'd rather buy quite a few serums with that money.

Blown away!

After trying many brands, organic toothpastes with big promises, etc., I let myself be tempted by The Smilist after seeing them on M6. They're reinventing the codes of the industry and it feels good! I bought the whitening toothpaste and the gum one because I have a big problem in that area that just won't fix itself... even with all the toothpastes I've tried. The Smilist toothpastes are truly amazing! My teeth are whiter after just a few days and my gums are much less swollen and bleed less. Now all that's left is to try the whitening serum!!
I highly recommend this lovely brand!
