While Belkyra is a non-surgical procedure, moderate to severe swelling can occur for up to two weeks following injection. It is advised that you NOT have this procedure done within a couple weeks of any major event as individual responses to this treatment can vary.
The most common side effects are swelling, bruising, pain, numbness, redness and areas of hardness around the treatment area. Belkyra can cause serious side effects, including trouble swallowing and nerve injury in the jaw that can cause an uneven smile or facial muscle weakness.
