I'm writing this assuming you had Botox to your forehead, and your eyebrows, not eyelids, are the problem.
Even though I tell my patients that their eyebrows will be immobile after Botox, sometimes you become very aware of the excess skin in your upper eyelids. Most of the times, the eyebrows didn't drop; you just lost the ability to raise them. And you don't like how it looks / feels.
You can get elevation of the tail of the brow with carefully placed Botox, but feel confident that Botox will wear off in around 4 months, and all will be the same as before you were injected. In fact, you'll likely get some movement / elevation around 6 weeks after the injection, so don't worry too much about this.
I hope this helps, and best regards.
