Ingredients from Amazon: (I'm not sure if it's correct because I do have these strips and there is no list of ingredients on the package, it's made in China and as far I know they don't have to put it): Glycerin, Propylene Glycol, Aqua, Phthalimidoperoxycaproic. If it's true then Phthalimidoperoxycaproic is stronger than hydrogen paroxide, but more harmful at the same time. However, I use it currently and it only works temporary for around 30 minutes, so I don't think these ingredients are true, it's rather fake whitening. Also, there is no information about safety regulations so I don't know what is that lady talking about... Only info that comes with these strips is how to use it... I do not recommend.
Depends on how stained or yellow your teeth are and how white you want them .I did mine every other day for two weeks and my teeth were 2 shades lighter and it removed yellow stains. If you want bright white teeth. It will probably take longer use depending on color of your teeth to begin with
Thank you for explaining it so well x
You're so welcome!
I wonder what the ingredients is because it says peroxide free on Amazon but doesn’t say what it uses instead.
