Hard lumps in Cupid's bow 3 days post Juvederm fillers?

It's pretty normal to have small lumps and irregularities early after fillers like Juvederm.  They can be from the product, product swelling, local inflammation, or tissue trauma from the needle.  In the short term light massage will help.  But just stay with the product for a week or so, and if you still have issues at that point see your provider.  Superficial placement of the filler would persist, and should be addressed by your doc.  

Dont panic!  This is still early.  You might have a small focal hematoma post injection. This should improve.  Be patient. Follow the advice of your injector but hang tight with this issue.  Hope this helps.  Good luck.

Swelling and bruising can persist up to two weeks after treatment and you should continue to see softening over this time period.  You can use gentle massage to help soften the "lumps".  If you do not see improvement contact your injector for an evaluation.
