I kept reconstituted botox in a freezer for about hour or two, then placed in refrigerator. Would it be still effective?

The potency of Botox decreases approximately 10% if frozen after reconstitution. It can still be used, however, if this is kept in mind with regard to the doses used.

Thank you for the question. I agree with the answer below, if you are still uncertain about using the Botox after freezing it you can call Allergan for their best recommendation. Best Wishes,Pablo Prichard
