Double bubble + animation not related to implant type
When double bubble and animation distortion occur together, the cause is often related to the muscle release that is done with the dual plane procedure. In this situation, the crease is not caused by the original fold but by the muscle pulling up there. Correction of the problem can be done by converting to the split muscle plane. There are several example on my website and other resources. Fat transfer do not address the cause of the problem but might help a bit.
