Significant Indentations from Botox Migraine Treatment?

Botox should not cause a depression of this sort. It looks like a progressive fat wasting condition called coup de sabre.  Like a knife scar to the face.  If this is the case it can sometimes this can be treated with fat injection.

Dear wikit626, the type of marked atrophy of the full thickness of the skin, shown in the picture, is extremely unlikely to be caused by botox. Your dermatologist can best diagnose the exact cause. To me, it looks like either localized scleroderma, or "post-steroid atrophy". There are a few cases in the medical literature , where the simple act of a needle stick in the muscle was followed by localized scleroderma. No cases have been reported following Botox injections , as far as I know.
