Can B12 vitamins help eliminate Botox by repairing the nerves? I have severe eyebrow droop on day 6. Will this get much worse?

This will improve in 3-4 months after it has worn off. In the mean time, thermage/venus legacy and fillers will help improve lift this area. See an expert. Best, Dr. Emer.

Unfortunately if you already have a brow droop it likely won't get better.  You will have to wait 3 months for it to fully wear off.

It seems like you had too much injected into the forehead in relation to your glabellar or frown complex. Botox injected into the frown causes a lift and typically requires 20 to 30 units while the horizontal forehead lines typically require fewer units such as 10 to 15 units. You are also at day 6 and certain muscles groups can become less active over others. i would give it a full 2 weeks and you should be better.  Check back with your injecting provider and adjustments can be made to lift the brow
