I haven't tried the most expensive kinds of eye shadow but all the others I have use just don't lat more than an hour or two and then they all gather somewhere in the crease of the eye. Why is this? What can I do to prevent it? And how do celebreties keep their smoky eye makeup on? Is there any secret I am not aware of? Even if I'm just sitting in my room reading the Beauty brains the eye shadows just don't last.
