I've Got Muscle Spasms in my Upper Lip After Juvederm. Is This Dangerous?

Hello,

I would not be overly concerned about the twitching--it is likely just from some irritation after you injection, and will resolve with a bit of time. 

In the future, make sure to select the best possible surgeon for your injections. What seems like a simple thing, is actually quite detailed and you should put yourself in the best possible hands when dealing with your face. It's definitely worth it!

Best wishes,

The side effects you describe from your injection should subside with time.  Often, due to swelling and/or mild irritation from the product, nerves that supply the skin and the surrounding structures (like muscles) can become irritated and swollen, causing them to misbehave.  One of these very common occurrences is the spasm or twitching of a muscle. Applying ice to the area for approximately 48 hours after the procedure can reduce swelling and thus decrease the amount of irritation the nerve experiences. 

If your symptoms persist, be sure to follow up with your injector.  Seeking evaluation by experienced clinicians who have a true appreciation of facial anatomy and knowledge regarding side effects and treatment options are always helpful and safe. 

The bruise is common and it is likely that the nerve was irritated from the injection. It should subside in a week or two. If not, or if there area any additional issues, I would highly recommend a second opinion consult. It seems as if the location you used may not be the best fit. Best of luck.
