Lips Drooping After Restylane

This is most likely the bulk of the product causing the asymmetry and not nerve injury.  I would wait until at least 2 weeks after the injection to see if the problem resolves on it's own.  If it is still a problem, consider just dissolving it all away with an injection with Hyaluronidase (an enzyme used to dissolve Restylane).  The most common complication from Restylane is improper placement of the product and that sounds like the problem in this situation.

As the other panel members suggested, the more likely scenario is that you have an uneven distribution of filler product.  This can be easily remedied with hyaluronidase which will dissolve the product.  Most importantly, it's imperative that you express your concerns to the one that did your treatment for a proper assessment and remedy for the situation.  Your appearance is your most important asset, being proactive will benefit you.

The crooked smile comes from Botox and unlikely from Restylane injections. If you cannot move a part of the lip and no Botox was injected, then you should see a neurologist.
If there is only asymmetry between the two upper halves of the lip , it can be corrected by either injecting more Restylane one one side or removing some from the other using Hyaluronidase.

I am not aware of any paralysis cases after Restylane. There may be asymmetric amount of filler on one side making it bulky and not mobile enough, yet. It should improve if that's the reason. Your physician may be able to reassure you and if you haven't already, you should see them immediately for an evaluation.

Thank you for your question. This is probably improper placement of the filler. The bulk of the Restylane is causing the asymmetry and not the nerve. I suggest giving it 2 weeks to resolve. If it still persists, you can have the filler dissolved with an enzyme known as hyaluronidase. Best of Luck!

You are probably describing a bulk effect, not nerve damage.  If it doesn't improve soon, you can get hyaluronidaseinjected  to dissolve the Restylane.  You should go back to the way you were before Restylane was injected.

It is so important when injecting fillers into the lips to get the product in evenly and symmetric. If you had a dental block before the procedure this can make it harder to get that nice even look.  Have the doctor who injected you dissolve the Restylane with a little hyaluronidase. Your lips will swell after the hyaluronidase injections but in a couple days you will notice your bulging uneven lips disappear. 

If Restylane is not injected evenly between the right and left sides of the lips, the lips may appear asymmetric when you talk or smile.  This can be corrected either by adding more to the smaller side or by removing some Restylane with hyaluronidase.   In addition, swelling of the lips may be asymmetric, so you should wait a few days for swelling to go away before fully judging the appearance of the lips.

Restylane is a popular and effective dermal filler that can be used successfully in me lips and in the nasolabial folds. When using this filler in the thin tissue of the lips, it is essential to create a balanced result between the mucosa and its intersection with the skin. Also, a discussion he had with the patient to determine how much of a pout effect they would like to create. In your case, it's best to be seen by your surgeon who can evaluate your lip and determine if you may need a little more rustling to help even out your results.
