Depressed Inner Brow After Botox Will Glabella Injection Help?

Knowledge of facial anatomy will play a role in your botox results being effective, placement in the wrong muscle can cause central drop.  Medial brow ptosis or descent of the central brow can occur for several reasons:
-Botox placed too low within the frontalis muscle along the forehead including central forehead.  The frontalis muscle elevates the forehead and by decreasing activity here the central brow can drop
-Botox placed too superficially along the corrugator.  The botox will again impact the frontalis muscle and paradoxically lower the central brow.
Botox is best injected by an experienced injector to lessen wrinkles while improving facial appearance.

    Glabellar injections to lift the medial brow may be what is needed, but injection to lateral forehead may give more balance as well.

If someone's brow is depressed after Botox on the forehead, Botox injected in the glabellar region of the lower forehead may help lift the eyebrows and the sagging mid skin.  Some patients also benefit from the lifting that Ultherapy can induce and as we age, there is a greater tendency for the forehead to droop. This diminishes the ability of the doctor to treat the horizontal lines of the forehead without making it sag more. The Ultherapy, by helping lift the forehead, might allow the doctor to continue injecting the forehead without sagging. The result of Ultherapy does not become apparent immediately and it can take six or more months to be seen.

What has most likely happened is that you received too much Botox in the central forehead or frontalis muscle that has weakened it and not allowed it to elevate your brows and instead it is heavy. This can also be caused by too low of an injection in the central forehead.  I am surprised that your lateral brows elevated without glabella or crow's feet injections, but this could be a relative from not injecting the forehead laterally.
