Does TXA Reduce Bruising After Hyaluronic Acid Filler Injection? A Prospective Half-Face Study

The overall purpose of this study is to evaluate the safety and efficacy of co-administration of TXA with HA in reducing swelling, bruising and pain after facial injection. We will do this by comparing HA to HA+TXA in patients undergoing facial filler injections. Patients undergoing facial filler injections almost always have the same type of injection performed bilaterally in order to maintain symmetry. This provides a unique opportunity where patients can serve as their own controls. Therefore, we will design this as a half face study. Patients will be injected with HA on half of their face and the other half of the face will be injected with HA+TXA. We will then assess swelling, bruising, pain, and overall satisfaction using patient self-reported surveys, physician surveys, and review of medical records.
