Can Botox Injections Be Reversed?

Short answer is No, Anti-wrinkle injections cannot be reversed.
However fortunately the treatment is temporary and after the expected 3-4 months your muscles will eventually return to normal activity and your facial lines will gradually revert to their pre-treatment levels.

Unfortunately, there is
no way to actually reverse Botox itself once it has been injected. This is why
many dermatologists prefer to inject conservatively at first, as it is much
easier to add more units than to try to fix problems caused by too many units. There
are some ways to try to mitigate an overdone Botox. For example, eye drops like Vasocon A or the
prescription drops iopidine, will help to tighten the orbicularis occuli muscle
and the eye will open up wider if too much Botox has caused the upper eyelid to
droop. An expert in Botox can also adjust the effect with more carefully placed
injections into muscles, which can counter balance the effects. One can also just wait out too much Botox
since the worst of it will last a few weeks and all will wear off in approximately
3 months.

Unlike some injectable treatments, the effects of a Botox treatment cannot be reversed. You can either get another treatment performed to "fix" the results or wait it out. Usually, it takes about 4 months or so for the effects to go away, after which your face will look the same as before your treatment.
