Lips Randomly Swell After Belotero? (photo)

Random swelling 2 months after a filler is not usual; but it may be related to sodium intake in your diet resulting in fluid retention.  In addition you may have excess product in your lip pressing on vessels. When the product swells it can put extra pressure on vessels causing compression and congestion in your lips. It may help to limit sodium in your diet which causes you to retain fluid. If this continues to be a problem you might also consider having some product removed although it will go down over the next few months on it's own.  

The intermittent lip swelling you are having two months after your Belotero injection does not sound like an allergic reaction, but it also is not the normal course for most people.  I would recommend returning to your treating physician to be evaluated to try and find a cause for your issue.  

Random swelling two months is not common but possible. It is unlikely to be related directly to the filler. It would be wise to consult with both your injector and your primary care physician to identify the cause.
