تبييض غسول الفم Colgate Max White

I can't say that this whitening mouthwash is super amazing. The taste is not bad, it doesn't burn, but after using it, you need to rinse your mouth well because it leaves a blue residue on the tongue and makes it slightly brighter.

The liquid inside is of a rather dark blue color. I liked the taste less than that of the classic Colgate mouthwashes sold in Ukraine.
There is some kind of sweetener in it that remains on the tongue and starts to ferment.
The liquid is quite strong, it burns the mucous membrane if there are any damages. It helps with whitening. But I didn't feel any particular differences compared to classic mouthwashes in this regard.
