Home Tooth Whitening Strips Unique Strips Black Intensive

In my opinion, this is complete nonsense. I used all the strips. I wanted to complete the entire course in order to see visible results. The black color of the strips may create the impression that something has been whitened when you remove them. But it's just a contrast effect. White will always appear whiter and brighter on black.
A girl commented below that these strips remove coffee stains. But, excuse me, I can remove coffee stains with toothpaste or mouthwash. These strips claim to whiten teeth by 4-6 shades.
There is no way that any whitening occurs! Not even by 1-2 shades. I looked closely every day and realized that it's just a hoax. Well, maybe by 1 shade if you convince yourself and truly believe it deep down inside.
After using all the strips, I absolutely saw nothing. Absolutely nothing!
Toothpaste cleans my teeth better than this nonsense.

Yes, these strips work well as a mask for enamel and gums. They are great for maintaining the effects of teeth whitening and removing coffee stains. However, they don't actually whiten your teeth. On the bright side, my teeth feel denser, which is a positive outcome.

The strips are good for removing plaque. They don't contain any hydrogen peroxide, so don't expect them to whiten the inner part of the tooth))) I applied them overnight for about 5-6 hours. My teeth became smoother and there is no sensitivity. I will add more after 14 days.

Great strips, the effect is visible after the first application, they remove the plaque after coffee and wine, excellent for the price)
