Wrinkles are divided into two types: the dynamic wrinkles (due to muscle overactivity, and disappear when the muscles are not active, or rested) and the static wrinkles (which form because of prolonged muscle activity, causing semi-permanent creases in the skin).  It is the dynamic wrinkles which we are concerned about now, as these are the ones that can be helped by botox cosmetic injection, which is given in the form of tiny injections into the muscles.  Static wrinkles can be helped only by injection of fillers, or in more extreme cases, by surgical facelifts.  It is primarily because prolonged contraction of muscles around the eyes tend to convert dynamic wrinkles to static wrinkles that early treatment with botox cosmetic injection is considered necessary.  (Think of a piece of paper that you keep folding again and again – these creases in the paper become permanent).
Botox cosmetic injection given directly into the appropriate muscles will cause the muscles to stop contracting.   The skin thus does not crease.  Usually you will feel the skin tightening at the injection site within 1/2hour from the time of injection.  The effect of wrinkle elimination will be very obvious after 4 days or so, and is expected to last between 4 to 6 months.

Botox Cosmetic Injection for Crows' Feet

Look at yourself in the mirror before the Botox injection, without smiling.  Then smile naturally and note the creases form by the outer corners of your eyes.  These are called crow’s feet.  These are the wrinkles that will disappear after your Botox cosmetic injection.  The disappearance of these wrinkles are what will make you look 10 years younger.
