Downtime if really variable. In most cases, if a person doesn't bruise there is no downtime. Most people will experience some swelling for 2-3 days but this rarely prevents someone from working or socializing. The unknown is whether or not someone will bruise and how severely. In certain areas, such as the undereye, bruising can be prominent and difficult to camouflage. Avoiding aspiring and ibuprofen for two weeks prior to your injection, taking Arnica montana before treatment and icing afterward can all help reduce the risk. Finding an experienced physician injector who uses cannulas (rather than needles) when appropriate can also reduce the potential risk of downtime. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon
