Botox for Crow's Feet

You can call crow's feet "laugh lines" or "character lines," but these slightly more flattering terms still refer to the same, inevitable sign of aging: the wrinkles that begin to form at the outside corners of your eyes when you hit your mid-twenties. They may show up earlier for people who don't take good care of their skin and later for those who do. But either way, crow's feet are all but unavoidable.

The skin on our faces stretches like a rubber band, thanks to a property called elasticity. This means that it can return to its original form after being pulled or compressed -- pretty important when you think about how much we move our faces. Unfortunately, as we get older, our skin loses its elasticity. That's why we form wrinkles and certain parts of our body start to droop. One of the main reasons for this is that our bodies' production of collagen and elastin, two proteins responsible for our skin's elasticity, lessens with age.
