Juvederm in lip corners (lack of). Dip in corners of mouth. Does this look bad, or is it common? (photos)

You are absolutely right that there is a discrepancy between the volume of your central lip and the corners. However, after 3 days you still have some swelling present which may make things look worse than they are. If after 2 weeks there is still a difference then you can have a little more filler added to the corners to make the tapered transition between the central lip and the corners smoother. If you have lost faith in your injector then I would recommend finding another physician injector in your area that you feel comfortable with. Worse comes to worse if you are not happy with the end result you can have the Juvederm dissolved with Hyaluronidase. Best wishes.

Your lips still look a bit swollen so it's too early to judge.  You should wait a week or two and see what things look like.  If not enough, more can be done.  If too much, enzyme can be used to remove some.It is important to discuss your needs, wishes, recovery time constraints, and budget limits with an honest and experienced surgeon, and receive bias-free personal advice. ALWAYS consult a surgeon who is certified by the American Board of Plastic Surgery, to ensure the highest standards of ethical practice and safe surgery.Reza Momeni, MD FACS American Board of Plastic SurgeryAmerican Society of Plastic SurgeonsAmerican Society of Aesthetic Plastic Surgery

Your lips are still bruised and still swollen so it is impossible to assess the situation.  You need to have patience and wait two weeks to evaluate.  Best, Dr. Green
