Visible ridge after Fat Transfer to tear trough. What to do? Help!

It's best to wait it out and let your body heal. See your surgeon and follow his recommendations 

Since you are only 9 days post fat transfer, it is still too early to tell what will happen. Understand that the first 2 weeks, the bumps and ridges will settle down tremendously and then over the next few months, the fat settles further and by 6months, you will see the full effects of the fat transfer. Be patient, follow up with your surgeon and take heart in the fact that its too early to be anxious about ridges and bumps that will likely improve over time.  

I know this is very frustrating, but this is very early. Stay in very close contact with your plastic surgeon's office and try to be patient.  Your plastic surgeons office will help you to understand the changes taking place. Sometimes, just after a dy to two, the changes can be remarkable.
