Before you even start Botox injections you will want to know how long they are going to last. After all, such treatment is not cheap and you want to get value for money and know what the ongoing cost is to be. In addition, you will want to organise your schedule so that you can have more done when necessary. The short answer to how long will they last is 2-6 months, or on average, 3-4 months.
However, much depends on the person and on their lifestyle. For instance, a person with strong facial muscles – usually, but not always, a man – will find the Botox injection does not last as long as someone with weaker muscles. Why is this? There are several reasons.
Botox works by temporarily paralysing the muscles that cause the wrinkles. If those muscles are strong, they will recover much more quickly. Another part of the equation is the time between injections. You may think you are saving costs by waiting until the muscle has quite recovered and the wrinkle is again established, but this is not the way to get the best result.
