Temporary swelling of HA fillers when I have a cold, flu or fever.

Thank you for sharing your question.  With the increased swelling of the facial tissues that accompanies your illnesses it would not be uncommon to have some sensitivity over your filler material.  There is nothing to worry about if the symptoms disappear within a few days.  Hope this helps.

This is a not uncommon reaction, although not noted in the literature as much as persistent delayed reactions. I have seen and heard of this but not necessarily with every infection. For some patients it is a one time reaction, for others it occurs more often with infections. This can present many months or even more than a year after the filler treatment was performed. There is no concern with this but if more prolonged or bothersome there are treatment options. As you very correctly questioned - it is theorized to be due to an immune response. 

Hi there,Thank you for your question.  There are no studies on this and I wouldn't worry because HA is found in the body naturally.  With bringing more blood flow to the face if there is an infection to heal, it might be that the areas with the filler are temporarily swelling because they are "water-loving" substances and as the infection begins to subside, less blood flow and thus less swelling. Hope this helps.All the best, Carlos Mata, MD, MBA, FACSBoard-Certified Plastic Surgeon
