Botox effectiveness varies due to injector dilution methods and unit counts
Dermatologists explain that Botox duration depends on the number of units received rather than how the solution is diluted at a medical practice.

Botox does not lose power suddenly
Experts state that the neurotoxin itself has not stopped working effectively. Hadley King, a board-certified dermatologist based in New York, notes that the product arrives as a freeze-dried powder before being mixed with saline. She explains there is no single correct way for injectors to prepare the liquid solution.
Dilution volume changes concentration ratios
Different medical providers use varying dilution volumes based on their specific technique and treatment goals. King says patients should focus on the amount of units they receive instead of the saline concentration. The total number of units determines how long the treatment will last regardless of volume.
