6 units of Botox under each crows feet. My smile was affected

Thank you for sharing your question and I am sorry to hear of your Botox side effects.  If Botox is placed too low below the crow's feet it can paralyze the muscles responsible for smiling, resulting in a facial imbalance.  As with all Botox effects it may take up to 3-4 months for this to resolve.  

I am sorry that you are having this problem. I have been using Botox for aesthetic purposes since 1991. In my experience, what you are describing may occur when Botox (or the other muscle relaxers, Dysport and Xeomin) are injected too low onto the cheek or if some should diffuse down onto the cheek and affect the muscles of facial expression responsible for smiling. In such a case, not only may the smile be affected, but it may be affected somewhat asymmetrically, as in your case. While, unfortunately, there no injection to reverse the effects of Botox, the results are happily temporary and last only until the Botox is metabolized away--usually somewhere between three and seven months, given individual variations. In many people, the undesirable effects often improve significantly even after only two months or so. Going forward, you would do well to seek consultation and treatment by a board certified aesthetic physician with expertise in the use of Botox. 

You should consider finding a referral to a new injector to see what if anything can be done to correct the asymmetry of your smile. Otherwise you will need to wait 3-4 months for your smile to return to normal. Thanks

Botox can take 3-4 months to wear off. In the mean time, venus legacy treatments may help soften the results and a touch up of Botox and/or filler may help improve the asymmetry. See an expert. Best, Dr. Emer

When crows feet Botox effects the smile, it was either placed to low on the face, too deep, or both. This unwanted side effect will usually resolve prior to the full 3 months that Botox typically lasts. Andrew Campbell, M.D.Facial Rejuvenation SpecialistQuintessa Aesthetic Centers
