This product is the same as Smashboxes O-glow lip gloss but $6 instead of $22!
It is supposed to change colour on your lips and become a custom colour depending on your chemistry.
I found it did not change my lip colour too much...but the same goes for the smashbox version. I bought this and saw very little change, then tried the smashbox, and it did the same. I guess it is just my chemistry. It is a really good quality gloss, and cost so much less then the smashbox version.

Love this lipgloss!! It goes on clear the turns the perfect pink for you. It really does work. It's nice and sheer too and smells like berries! Yummy!! I first had doubts when I ordered it but after the first time I used it it lived up to it's expectations. I already bought a second one.
