Different approaches
PRF (platelet-rich fibrin from the patient's blood) is a biologic, skin-quality-oriented approach; filler is volume-oriented. They address under-eye concerns differently, and which (if either) is appropriate depends on the underlying cause and the individual patient.
A high-stakes area
The under-eye is delicate and unforgiving — treating the wrong cause or treating inappropriately can produce results that are difficult to correct. That makes careful assessment, appropriate technique, and honest expectations critical, and it raises the bar on provider training and judgment. There's no universal right answer here; there's a careful clinical match to the specific cause.
What to do
- Treat under-eye selection as cause-specific and high-stakes, not a generic choice between approaches.
- Require careful clinical assessment of the underlying cause before recommending PRF, filler, or neither.
- Use appropriately trained providers given the area's delicacy and the difficulty of correcting poor outcomes.
