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

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

  • Tess Verified review

    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 to repair and strengthen the weakened enamel.

The promised results, delivered!

I've been using the product every evening for 3 weeks. I can see the color of my teeth evening out, between the front ones and the ones on the sides that tend to be less white. My teeth haven't become dramatically white, but I can see the effects of the fluoride and that's what makes me want to keep going. Are the effects long-lasting, or do you have to do this "treatment" regularly? We'll see! But I recommend it.

A WONDERFUL DISCOVERY

A real revelation! Both the toothpaste and the mouth spray stand out for their effectiveness and how elegant they are to use. The spray gives an instant, long-lasting feeling of freshness for impeccably pure breath. As for the night whitening enamel serum, it enhances your smile: when you wake up, your mouth feels light and your teeth are smooth and beautifully bright. Exceptional products that I recommend without the slightest hesitation.

We love it!

I hesitated for a long time about getting a whitening treatment at the dentist. Since I have natural sensitivity, I wanted to go for a gentler solution! Done, with the Night Whitening Kit! The results are there! A fresher, healthier mouth and teeth that regain a natural white over the days! I was skeptical! I'm not at all anymore! Thank you!!!!

I recommend it

I ordered a teeth-whitening kit from The Smilist website and I'm very satisfied. Delivery was fast, the packaging neat, and above all the product lives up to its promises: after a few nights of use, I've already noticed a real difference in the whiteness of my teeth. Easy to use and effective, I recommend it without hesitation.

Revolutionary

My teeth had yellowed because of cigarettes and wine... I was starting to hide my smile.
I tried the whitening serum and what a nice surprise to see results from the very first days.
I'm smiling again with real pleasure.
I'll happily, confidently
and eagerly discover your other products.

Thank you The Smilist
