We are all asymmetrical :)  Again, like others have said, it's hard to say definitively since we cannot see the whole picture.  Just looking at your picture, I think that a little Botox could be helpful and create a bit more symmetry.  

We haven't heard any changes from Allergan (the manufacturer of Botox) but sometimes with our patients I have seen it not lasting as long because they are under a higher amount of stress or increased their workout routine.  Other than those reasons, we haven't seen any change in duration with our patients.  Hope this is helpful to you.

It's completely normal to have swelling after injections.  Try not to be too critcal too soon.  Give it a chance to calm down (1-2 weeks).  Sometimes injection sites may be a little more swollen than other areas making one side look bigger than the other.  

You should be able to get Botox done before or after getting bloodwork done without any side effects.  Even the day before or after :)

I usually recommend starting Botox when the lines start to stay there when you are not doing that expression.  It sounds like its a genetic trait and so I don't believe that it would be too early to start.
