For one Botox injection the clinical results will normally last three to six months. If you want continued improvement, or if once the effect of this dies down, it will become necessary for you to have another treatment to maintain the cosmetic effect.
Q: I got one Botox injection, how long should it last and will I need to get others to maintain the look?

On average Botox injections should last 3-1/2 to four months. Studies actually show that if for the first year they put Botox injections on a schedule and consistently do them every 3-1/2 to four months they're going to last a lot longer because they will get better longevity and that's what I suggest to my patients.
