How to fix my hollow under eyes, don’t want to try anymore PRP or PRF (Photo)

Fat grafting can be very natural and safe in the lower lid. 2-4 cc can be grafted safely to each eyelid. However, like with PRP it may require a redo at 1 year if volume does not last.

You could always try fat transfer, although you have to know that fat also is not perfect. I would avoid doing much more filler because that could lead to issues down the line with lymph trapping around your eyes.
