Mouth Corners / Marionette Lines

My mouth droops at corners....kinda makes me look like a am frowning all the time Crying or Very sad
Top lip is thin, I am OK with fullness of bottom lip and dont really want to mess with that.
Any ideas that will make the corners turn up some?? Someone suggested Botox,but I would think that would make it worse
Would a filler on top lip only accentuate the problem?
THANKS!

hi
sorry for the delay
i think that botox would be a very good idea - the corner of the mouth is pulled down by a muscle called the dao muscle.
weakening it will raise the corner of the mouth. this should only be done by an experienced injector, however, since too much will cause problems.
i would put 4 units per side, divided into an upper point and a lower point.
the other option is filler.
a bit of juvederm or restylane in the marionette lines will also go a long way toward smoothing out that area. filler on top should be a good idea, just not too much.
