I Had Juvederm 2 Days Ago Around the Corners of my Mouth and Saliva is Pooling in Corners of my Mouth. Will This Go Away?

The typical side effects associated with hyaluronic acid injections such as Juvederm or Restylane include bruising, redness, swelling and pain. These occur in as high as 90% of patients and usually resolve within one week. It is possible that some of these side effects may be affected by the injection techniques such as fan like injections, higher injection volumes, and more rapid injection times. I always recommend waiting at least one to two weeks for the swelling to go down after the treatment before worrying about any long-term adverse effects.

The most plausible explanation for saliva pooling after Juvederm injections at the corners of your mouth is that there is some  bruising which has temporarily interfered with normal muscle contraction. This will be transient, but consult with your physician.
