How do I know if I have scar tissue build up in my lips from Voluma lip injections? (photos)

Thank you for sharing your excellent question.  In the majority of cases dermal fillers like Voluma do not result in the formation of thickened scar tissue, rather the hyaluronic acid becomes incorporated into the tissues to leave a soft, natural quality to the skin.  Voluma placed into the lips may last for several years so I would advocate for continued dissolving of the product.  Hope this helps.

Without examining you, it is literally impossible to say whether or not you have scar tissue. It is improbable, however. If you don't trust the surgeon who has seen you in person, you could always get a second opinion. I am sorry that you've had such a bad experience. In general, I don't like to use Voluma in the lips. There are other fillers that I prefer such as Volbella or Vollure. 

It is impossible to say if you have scar tissue without examining you in person. I would say that the chances are very slim especially since the surgeon who examined you in person agrees. Best of luck.
