Polish lasts longer on artificial nails, because on natural nails you have more oils in your bed and it's going to slide off a lot easier. It's just like having the oils on your eyelids, when you apply makeup, why does it smear? It's the same thing. It's an artificial nail, which doesn't have the oils in it, so it's going to last three, four times longer.
