How many filler injections make an injector competent?
A clinician pricing out training wants a number to aim for. A published framework gives one, with an important limit on what it proves.
The numbers one framework suggests
PubMed Central carries a study whose summary reads: "In this study we establish an educational framework in aesthetic medicine by defining the progression from novice to competent and expert injector levels, suggesting 4 years of practice and over 790 filler and 550 neuromodulator injections for competence, and at least 6 years with 1840 filler and 1310 neuromodulator injections for expertise."
For filler alone, the framework points to over 790 injections for competence and 1840 for expertise. The study is Identifying Levels of Competency in Aesthetic Medicine: A Questionnaire-based Study.
Why the word "suggesting" matters
The passage says the framework is suggesting these figures. It describes levels of an injector's progression and attaches practice years and injection counts to them. It does not say that a course containing that many injections certifies anyone, and it does not set a rule a clinician in Morristown, or one who trains in the neighbouring big-city market, must meet.
The Dreyfus model of skill acquisition describes skill as developing through stages, which is the same kind of progression the study maps onto injectors.
Comparing a course to the framework
Look at how large the gap is between a course's hands-on injections and the competence figure. If the gap is wide, read the course as one step rather than the whole route. The paper on the need for regulated training and certification in aesthetic medicine discusses why training structure matters at all.
The takeaway
Use the figures to judge how much practice you still need after a course, not to judge the course itself. Ask any program how many of its injections you would perform yourself, because that count is the one that moves you toward the framework's competence figure.
