Can 1.25 units of Botox improperly injected into upper cheek area (too low on the crows feet), cause smile paralysis? (photos)

1.25 units is a small amount of Botox and will not likely cause any problems.  However, if you do develop any unwanted effects, they will wear off in the next few months.

Average crows feet dose is 6-12 units each side. Even if injected too low, I don’t think 1.25 units would do anything at all. I have never injected such a small amount anywhere.

Small doses of Botox can cause smile paralysis if enough is injected in the correct area. 1.25 units is a very small amount and even if injected intentionally into the smile muscles, it would probably cause minimal weakness for a few weeks. Additionally, your injector would have to place the Botox about an inch under your eye at or below the cheekbone to paralize the smile muscles.
