Is there a way to speed up how fast Botox wears off?

I recieved Botox about 6 months ago and have seen no improvement in my brow droop. Not willing to get more injections to correct it. Why do people say it will be worn off by 6 months when this is not even close to the case for so many people? The droop is extreme. I haven’t recognized myself for 6 months. I avoid looking in the mirror. Is this actually going to go away? I have movement in my forhead now yet no improvement with this still. Can I speed it up somehow?
