Botox
Will my Botox side effects get worse over time and how long will they last?
It is difficult to give you an exact answer without before and after photos. The maximum effect of botox is at 2 weeks. I would advise you to follow up with your injector at this time to re-evaluate. Fortunately, this may be a opportunity for your injector to balance your results with a few additional units. Regardless of what you decide, botox will naturally metabolize and wear off in 3-4 months after injection and you should feel heaviness reducing over the next few weeks. As always, make sure to consult with an experienced, board-certified provider.
Clinical Context
If side effects like heaviness, asymmetry, or a droopy brow show up, the real decision is whether to wait them out or seek treatment, since most reflect the injection settling into muscle rather than a worsening reaction. These effects typically stabilize within the first two weeks and fade as the muscle gradually regains normal signaling over the following months, rather than intensifying. Worsening after that early window is unusual and worth mentioning to whoever treated you.
