Hismile purple tooth whitener/colour corrector serum

[AlwaysPrettyOnTheInside]

Has anyone used this, does it work as well as in the videos they show?

My son and I bought HiSmile a tube each . Nearly used the tube and neither of us could see any difference
I wouldn't buy it again

Did you buy the purple serum or the toothpaste?

Get some Pearl Drops, the pink one, it's the same thing (the colour correction is due to the colour of the toothpaste) for a fraction of the price. It doesn't last (neither does the hismile) but you do get instant results so I just use it if I want to look a bit whiter before I go somewhere
