Am I a good candidate for lip fillers? Looking to shorten philtrum distance as well as add volume to top lip. (Photos)

you are actually looking for a lip lift.  The scarring is actually quite well hidden when done correctly. 

Lip fillers can only go so far!  You pointed out very impressively about the cupid's bow and the distance between the lip and the nose.   That's hard to change with fillers.  If the distance between your upper lip and the nose is short you are in luck.  We can place fillers and give you beautiful results as per my video below.  The key is a short distance in the cupid's area.  And that can only be shortened surgically.  Do your research well.   There's only one or two surgeons in the country that do this well and can get you great results.   Good luck. 

Hello
ABSOLUTELY. you are a good candidate for lip filler injections. I would anticipate the results are going to be great.
After injecting the lips, and volumize those, that would make the philtrum look shorter. During the injection it should be evaluated.
Choose a experienced physician with an artistic approach.
(HA Fillers such as Restylane, Belotero or Juvederm would do fine
