I got Dysport injected next to my nose 3 weeks ago and now my smile is gone! When can I expect it to start to fade? (Photo)

Thank for you your question and providing a picture. I see what you are talking about and I am sorry you are not happy with your results. Dysport typically takes 3-4 months to wear off. Unfortunately, facial exercises will not speed up this process.

I'm sorry you are unhappy with your treatment results. The effects of Dysport will fade gradually over 3 to 4 months.  There is no product or exercise that is known to make it metabolize faster.

Dysport or Botox injected to the side of the nose can diffuse to the muscles that elevate the lip.  Often in small amounts, this can be used to decrease the gum show during smiling.  However, if too much is used or if the injections are done to far laterally,  it can cause the upper lip to lose upward mobility.  The good news is that around the mouth, neuromodulators tend to now last as long as they do in other areas of the face.  It will likely start to abate in a few weeks but may not fully go away for a few months.  Try to utilize the muscles as often as you can throughout the day.  As far as metabolizing dysport faster, nothing has been proven but people with higher metabolic rates (runners) tend to burn through it faster. 

I am sorry to hear about your experience.  These situations certainly are frustrating.  The duration of time that the effects will persist can be quite variable.  To some degree this is related to the dose of dysport used.  If only a tiny dose was used the duration of effect may be quite short.  Unfortunately there are no exercises or "antidotes"

Unfortunately too many units were placed in the inappropriate locations making it change your smile. I suggest seeing a cosmetic dermatologist with experience in 3 months as this will take time to resolve. Best, Dr. Emer.
