In addition to drinking plenty of H20, using a doc-approved eye cream will help hydrate skin from the opposite direction. To best prevent crow's feet, you want to look for an eye cream with mild, moisturizing ingredients like glycerin, squalene and cucumber. Also make sure it comes in an opaque tube, not a jar, to prevent bacteria and degradation of active ingredients.

Swift recommends SkinMedica TNS Illuminating Eye Cream, $92, for its ability to "reduce the appearance of fine lines and wrinkles and improve skin texture and tone."

#Realtalk? While staying hydrated and using eye cream certainly help in the war on crow's feet, there's really no fix as effective as a smidge of Botox. "It's the 'gold standard' and most effective treatment for crow's feet," says Swift. "Nothing else works as well or will last as long."

Though "Botox" can sound like a dirty word if you don't know anyone whose tried it, Swift assures that millions of men and women use the stuff to treat wrinkles around the eyes. "They recognize the efficiency, value and natural-looking results," he says.

Here's how it works: Botox temporarily freezes the muscles that produce crow's feet. The results last between three and four months. It isn't a gory or painful process and, when done correctly, won't make it look like you had "work done," Swift promises. "It will simply reduce the appearance of those bothersome lines."

Of course, no one needs Botox, but if you're serious about getting rid of your crow's feet, this is your best bet. "Just make sure you go to a board certified plastic surgeon, who has knowledge of facial anatomy, in order to obtain the most natural results," says Swift. If your crow's feet are particularly deep, Swift recommends asking about adding a thin filler called Belotero.
