I first bought this because I thought it sounded "cool", but I wouldn't purchase this again. I didn't like the colour that it applied on my lips, as it was quite light and sheer. Not flattering. I also didn't touch the teeth whitening..

I wouldn't purchase this for my own personal preferences.
The first being that my lips are naturally quite pigmented (red tone) and the lipstick is sheer. Because the shade was a brighter pinky orange color it looked funny on my lips however it was really moisturizing!
The other thing is that I am very skeptical about what I put on my teeth so I stayed away from the teeth whitening portion of the product.
I ended up giving this away to someone who was more thrilled about it than I was.
