I've used so many of these lip stick duo's that I've lost count. This amazing lip stick is meant to give 12 hours of colour. The actual lip stick is applied to lips and sort of hardens on lips, giving lips a plastic seal of colour, while the gloss adds a luscious shine to lips. The only problem I've ever had with this lipstick is sometimes the lipstick peels off here and there and looks really funny, I'm not sure if anyone else had that problem but I've had that problem. It's simple to remove the lipstick, all you do is use a little make up remover and gently wipe lips and you're good to go!
