“How long does Botox last for?”

I have been injecting Botox for aesthetic reasons since 1991. Although Botox typically lasts for three to six months, what we have found since those early days is that if an individual undergoes a treatment cycle of between four and six Botox treatments (on the same anatomic site) at four month intervals, the results of treatment thereafter may last far longer. Following the initial treatment series, I have personally had patients whose results lasted a year or longer between treatments (I include myself in this). We believe that the reason for this is that repeated treatments actually shrink the muscle and there is likely an element of the Botox retraining the muscle not to overreact as it it did prior to treatments. However, if one prefers not to undergo this initial series of treatments at the fixed four month intervals, the Botox effect can be anticipated to last between three to six months, on average.

It depends upon the age of the patient as well as the depth and duration of the wrinkles. As a general rule, a treatment with Botox or any of the class of drugs known as neuromodulators will last about three to four months. It's always a good idea to consult with the injector and return for a follow up treatment before the wrinkles reappear.

While the typical effects of Botox can last up to 6 months, studies show about 50 percent of the relaxing effect of Botox is gone at 3-4 months. To maintain a natural look it is best to do Botox every 3-4 months so you don’t go back to square one!

Botox generally lasts about three months. The longer you use it, it can last longer because the muscles become smaller lengthening the duration of the effect. Dr. Stolar

Botox typically lasts between 3-4months.

Generally 3-5 months, depending on the patient's response.

Usually about 3 months.
