Botox cause cheekbone to look less defined, dropping on one side/nerve damage? (Photos)

There are two signs you've had a bad Botox injection: Unusual results such as facial asymmetry (one side doesn't match the other), overarching eyebrows, a drooping eyelid, or not being able to move the forehead at all. In general, Botox lasts 3-4 months. There will certainly be patients in which in lasts longer, in that 4-6 month range, or shorter, in that 2-month range. It is also common for first-timers to notice that it may not last as long initially but may last longer after the second treatment.

Mostly the differences are on the basis of lighting. Botox has basically worn off. However, it can still be a period of time before the training effect on muscle volume wears off. Perhaps someone other than a "nurse" should be doing your injections. Your lips seem to be bigger in the second image and not particularly natural. Removing filler volume from the face can also be beneficial and you should consider this option if you continue to have concerns about your appearance.

From the submitted photos and the description of your concerns they are unrelated to your Botox injections. The effects of Botox are temporary, lasting three to four months on average. If you are wanting to enhance your cheekbone area you can consider fillers such as Restylane Lyft or Juvederm Voluma.
