Anti-wrinkle treatment has become synonymous with a single number, units. In practice, unit counts are the least interesting part of the protocol. The anatomy of placement, the balance between muscle groups, and the patient's own movement pattern all matter more than the total dose.
A microdosed approach distributes smaller quantities across a wider map of muscles. It produces a more natural result with shorter duration, which sounds like a downside until you consider that shorter duration also means more frequent review, more room to correct, and a treatment that grows with the face over time.
If you have ever been told a fixed dose regardless of context, 'the forehead is 20 units', you have been treated by a menu, not a clinician. Your face is not a menu.
