Not only do they look cool, wearing your favorite shades whenever you're out in the sun is your armor against crow's feet.

"It is important to wear sunglasses to protect the delicate eye area and to prevent excessive squinting, which over time causes crow's feet lines to form," explains Swift. In other words, simply throwing on a pair of sunnies works double duty to prevent sun damage, as well as the repeated contractions in the skin around the eyes that cause crow's feet to form over the years.

Try a polarized pair for extra protection, like these sharp Clubmasters.

You've heard it time and time again, but only because its true. Sun damage is a leading cause of fine lines and crow's feet, including your dreaded crow's feet. According to Swift, slathering on the sunscreen every morning -- even in winter -- is a crucial step in the fight against crow's feet. (Though it's more preventative than effective for treating existing lines.)

"You hardly ever hear about exfoliating under the eyes, because the delicate skin is so sensitive," says Edlich. But recent studies have shown that just the right amount of exfoliation can work to smoothen skin and reduce the appearance of crow's feet.

Radical Skincare Age Defying Exfoliating Pads, $75, have a gentle enough formula to use under the eyes, and "have been shown to help reduce crows feet by 50 percent within two weeks," says Edlich. (In the meantime, they leave skin supersoft.)

"Each pad is infused with a blend of Alpha Hydroxy Acids and Beta Hydroxy Acids, as well as anti-aging properties and skin calming agents," Edlich continues. "Aloe, which helps sooth the skin and perfect the under eye area, is the second ingredient."

Exfoliation also allows moisturizing skin-care ingredients to absorb more effectively. Just make sure not to use a regular face scrub under your eyes, which could be too harsh and end up doing more harm than good.

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.
