How long does it take for wrinkles to fade after first botox injection?

Any wrinkles from movement will improve with botox injections and stay improved for 3-4 months.  they go back to their normal state after the botox was injected.  Sometimes less, sometimes more depending on the person and their musculature and daily activity (ie amount of expressivity).  Best, Dr. Emer.

The amount of time it takes for "Static" wrinkles (those that are present when your face is a rest) to fade depends on how deep the lines are before you start doing Botox. Everyone is different, and while age does matter, you could be 40 or 45 with a deep wrinkle, or 60 with hardly any wrinkle. The best time to start using Botox is when you see that line with your face at rest. Most patients will need to have Botox done every 3 to 6 months. If you are 40 years old, and the line between your eyebrows is not too deep, it shouldn't take a whole year to see it disappear. Still, remember the line won't go away immediately. I recommend you continue to stay on top of your treatments - when you can totally make the movement again, it is time for the next treatment.
