Depends on the Physician dilution can you determine how many units are in a syringe. The average cost per unit can range from different locations, anywhere from $10-$18 per unit.
Botox is purchased by the office by the vial (usually 100 units). Patients are then treated with a specific number of units depending upon their muscle bulk and muscle activity. The unit price ranges all the way from $5 (hair salon, internist, etc) to over $12 (expert physician injector). As with everything else in life, you get what you pay for. Seek an expert injector plastic surgeon or dermatologist. Even in the expert injector category you will find a relatively wide range of pricing available to you. I hope this information is helpful.
