After Botox injections for crows feet, I cannot close my eyelids fully or cry properly. How long before the effects wear off?

Results are most noticeable 2-3 weeks after injection and should wear off in 6-12 weeks.  I suggest you see your physician and get eye drops and an evaluation.  Best, Dr. Emer.

It is likely that your follow up injections are what caused your symptoms.  Follow up with your provider.  Botox will typically last 3-4 months but your symptoms should improve within 4-6 weeks.

Thank you for sharing your question and I am sorry to hear of your side effects.  This sounds as if the second round of injections likely caused the difficulty with closing of your eyelids and inability to cry properly as Botox's effects kick in fully by 2 weeks.  As you had little botox placed I would anticipate this to wear off in a month or two but may last up to 3-4 months.  Unfortunately there aren't any options at reversing its effects.
