Bruising and mild swelling at the injection sites are the most common side effects of Botox. Rare adverse reactions include developing an eyelid droop or heavy brow post treatment. Both of these effects can last a few weeks but can usually be mitigated with either eye drops or a small “Botox tweak” to balance the muscle action. After treatment it is important not to lie down for 4 hours, not to exercise the day of treatment and to treat the face gently for 12 hours. This post care protocol can help to minimize these adverse reactions. Both the eyelid droop and heavy brow are entirely reversible within a few months.
