Botox costs can vary anywhere from $200 to $400 or more depending on the physician, location, units purchased, desired profit margin, ongoing promotions, etc. Many doctor's offices price Botox based on cost per unit, but others price Botox injections based on the area of the injection.
Answer â In most patients, Botox lasts between 3-4 months. However, thereâs quite a bit of anecdotal evidence suggesting that itâs possible for patients to achieve results that last up to 6, 9 or even 12 months after consistent, long-term and properly-administered use of the Botox product. In other words, what determines how long the effects of Botox lasts is: 1  the dosage (and whether or not itâs been properly diluted) 2  the duration & consistency of use. 3  the skill/experience of the injector or surgeon who administers the injection.
