How do I get rid of line of demarcation? (Photo)

I suggest seeing a cosmetic dermatologist who not only does filler injections but is a facial contouring expert.  There are many ways to blend this with other fillers or dissolve some of the fillers you already have in there.  Best, Dr. Emer.

Thank you for your photographs and questions.  I can see your areas of concern, and I would recommend you use your remaining restylane along your lower eyelids/upper cheek to better smooth this transition.

It is difficult to see exactly what the area of demarcation you are referring after your filler with Juvederm Voluma. Is the line a:1)  An area of depression--if that is the case then additional filler may be useful.2)  It is a change of color-  This may of been present before filler and more apparant after filler.  There is a chance the filler was placed too close to the skin causing a color issue.  You will need an exam for a definitive answer.  I hope this helps.
