Droppy eyelids from botox are extremely rare. What is more common is a lower or flatter brow from too much relaxation from botox in the forehead. If your forehead becomes completely relaxed then you may not be able to raise your eyebrows - this leads to a feeling of heavy brow and can make the brow flat and seem like you have droopy eyelids but the eyelids really are just weighed down by the heavy, relaxed brows that are no longer raised up by forehead muscles. The goal of botox is to acheive a balance betwen the muscles that pull down on the brow (the muscles between the eyebrows) and the muscles that raise or elevate the brow - the forehead muscles - so that the net effect is a slight overall improvement of the brow arch making the eyes look more youthful and rested.
