There is no specific timetable for touch ups, but most patients can see their final result after two weeks so it makes sense to wait until after that time period.
Juvederm lasts 6-12 months (voluma 12-24 months) in most people, with swelling lasting up to 2 weeks after treatment. I advise coming back after the initial two week period, but consult your injector for their own evaluation. Best, Dr. Emer
