Why did Juvederm filler under eyes produce irregular contour and how can I fix it? (Photo)

Thank you for your question. It is best to wait for your in-person assessment with your injector to determine the best course of action for you. It is very possible, based on the amount you received, that a top-off of the filler may be what you need to create a more symmetrical look. However, it is also possible that you will need some filler dissolved if there is an area that was overfilled. 
I am glad you are going to a doctor that has extensive experience in treating the tear trough area. The delicate skin in this area requires ultimate precision and a gentle touch to create a look that is both natural and symmetrical. I wish you all the best as you continue to pursue your aesthetic goals. 

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Juvederm is a great product that we use daily in our practice.  You mentioned many areas injected with just one syringe so the chance of one of those areas being underfilled is a good possibility.  One syringe only consists of 1 cc/ml and is typically not enough to cover all those areas.  Most importantly, Juvederm is not recommended in the tear trough area as it can tyndall, which means it can have a bluish look to it.  I would find an experienced injector who has a variety of different fillers to choose from that work best in specific areas of your face.  Best of luck!
