Maybe it would last 14 hours if you never eat or drink anything? But I didn't buy it for it to last 14 hours - I bought it mainly for the colour. It did last pretty long though, the only drawback being that in order to be long lasting, it tends to feel very dry on the lips. I'm willing to live with that though :)

This lipstick is my favourite of the many different lipsticks I have tried! It truly stays on your lips, and even after eating or drinking, colour will still be there- it will still leave some lipstick marks on your glass or napkin, but overall even after that you likely WON'T need to reapply. I also like that it is moisturizing enough to use without needing to apply lip balm first.
I try to get this on sale, as I do find it can be a bit expensive, but I am still willing to pay full price for it. If you tend to have rough or dry lips, I recommend exfoliating them first since this lipstick goes on a bit thicker than most and would show this,
The only draw back I have to this lipstick is that they don't make it in as many colours as I wish they did!

Super long lasting color. Also has a fruity smell to it, and color is gorgeous! Easy to apply, as it glides on smoothly, like lip gloss, but when dries stays on lips for a long time.

This is one of the best "lasting" lipsticks that I have tried. It isn't super shiny (which means it isn't super sticky either) but it also doesn't leave you with that dry caked on feeling that other lasting lipsticks can. It holds up very well. Certainly not 14 hours but if I put in on first thing in the morning before work it lasts through my morning tea and usually lunch as well which is far better than any others I've used. The smell is great too.
