Botox caused droopy "Captain Spock" eyes , how can they be fixed?

Simple. Two more injections over the lateral brow will relax this look, and bring your normal appearance back.

If one or two units of Botox is injected an inch or more over the outer two thirds of the eyebrow, it should help minimize the contraction of the previously untreated frontalis muscle that is compensating for the inability of the middle forehead to lift. Your inner eyebrows seem to be low and if no injections were done in the glabella, the region between the eyebrows, then treating the glabella can help lift the middle forehead and eyebrows. Don't do anything else more aggressive so close to your wedding. Congratulations, by the way!
