Why can I see bumps after getting filler for smile lines?

Thank you for your question. It is common to see some bumps after filler. It should settle given some time. If you're still unhappy with your results, I would suggest following up with your injector. Best of luck! 

Great question. 
When dermal fillers are injected the material expands the surrounding tissue. This is normal, and may cause some raising of the skin surface. Over a few days this subsides to a flatter surface, while maintaining the cosmetic improvements for the life of the filler.  There are also known complications to filler injection, and not every ‘bump’ is the same.  This may require an in-person evaluation by your injector sooner than your follow up.  For more information, be sure to find a trustworthy surgeon, with experience and impeccable credentials in your area.
