Disclaimer: Sleeping in eye makeup -- any kind of eye makeup -- will probably earn you a scolding from your ophthalmologist. However, there are some formulas that do more than just let you create the perfect cat eye. They hydrate and protect your lids and even promote healthy lash growth.

Sisley Phyto-Twist Eye, $50, is a chubby liner and shadow crayon that contains green tea and camellia extract for moisture and antioxidant protection. Similarly, Grande Naturals GrandeLiner, $44.95, is made with a lash-boosting complex that will make your lashes grow longer and thicker in just four to six weeks. The formula is also waterproof -- once it dries, you can forget about it -- which makes taking it off at the end of the day even easier to avoid.
