So, it says 24 hours stay fast, i used this product, and i was very unsatisfied with the outcome. It seemed that during the late afternoon it was not "there" anymore, you couldn't notice anything like it look in the morning. Its got quite a thick substance to it, and its not easy to blend, i had a lot of problems trying to blend this product onto my skin, i added some cream, but it didn't go so well! I would definitely not be buying this product again.
