I have tried 3-4 from the market and they did not have the same performance as this one. I smoke 5 cigarettes a day plus 2 coffees, my teeth stain quite a bit. It's not the type that whitens my teeth, but it keeps them at a good level. It is quite more expensive, but it brings better results, I will buy it again.
Advice from the dentist: use it every day for 1 month and then as maintenance, use it twice a week.

It is very black toothpaste and a little disgusting and expensive, without noticing any significant whitening.

Initial evaluation (4 stars):

After 3 weeks of use, I didn't see significant results regarding whitening, but it does leave a nice feeling of cleanliness in the mouth.

I don't know if I will buy it again, although I don't exclude it yet.

Update 22/02/2020 (5 stars):

In the end, I have bought 4 more tubes so far and I can say that it does the job when it comes to whitening, it whitens a little and maintains the color at that level. As for cleanliness, I stick to my initial opinion.

I will probably find it difficult to switch to another toothpaste.

Special product compared to classic toothpastes. Refreshing mint flavor. With frequent use, you see results.

Definitely does something, much more than similar products. Unlike other similar products, it did not irritate my teeth/gums.

Good, but bad packaging. With the first use, the tube opened from the top and the cream came out from there

Whatever anyone says is not enough for this toothpaste. I have tried all the good whitening toothpastes, Elgydium, Curaprox, etc., they don't come close to it. Its ingredients are unique and cannot be found in any other toothpaste. Incredible results with brushing three times a day. Nice feeling after brushing. Its only drawback is its price, but in this particular case, it is worth every penny and more.
