Sensai 38°

Sensai mascara.
The best waterproof mascara I have ever found. I have tested many a waterproof mascaras, and continue to just in case; but this beats them all. It has silk extract and basically once it sets on your eyes it stays on until water of a heat of 38° goes on it and will then crumble off. This means that tears or watery eyes will not effect it. But once in warm water you can crumble it off your eye lashes and therefore do not need some horrible eye makeup remover.
Worse case scenario, your mascara will not give you unsightly smudges but crumbles of mascara you can brush off. I cannot recommend this product highly enough. But like all products it depends what you are looking for.
It does give your eye lashes body, but not as much as other mascaras I have tried.
Therefore if waterproof mascara is your main priority than this is the mascara for you.
