This is a thoughtful question, and I understand why you’re interested in it. The under-eye area is one of the hardest places to treat, especially when the concern is deep hollowness in the 50s, where there is often a combination of volume loss, thinning skin, and changes in the lid-cheek junction. A quick clarification: when people talk about PDGF (platelet-derived growth factor) in aesthetics, they may be referring to a growth-factor-based regenerative product rather than traditional PRP (platelet-rich plasma) or PRF (platelet-rich fibrin). These treatments are related in concept, but they are not the same thing, and the safety data for each is quite different. Why many providers are cautious about injecting it under the eyes The lower eyelid is a high-risk anatomical area because the skin is extremely thin and there are important blood vessels nearby. Any injected material has the potential to cause: Swelling or prolonged puffiness Lumps or irregularities Inflammation Vascular compromise (rare, but potentially serious with injectable procedures around the eyes) For PRP and PRF, there is a growing body of evidence suggesting they can improve skin quality, fine lines, and crepey texture when injected superficially or used with microneedling. However, they generally produce modest improvement in true volume loss. For PDGF-based injectables, the situation is less clear. While growth factors play an important role in wound healing and tissue regeneration, there is limited high-quality, long-term evidence specifically supporting the safety and effectiveness of injecting PDGF products into the tear trough area. That is likely one reason you are having trouble finding experienced providers willing to offer it. About the “amazing before-and-after” photos I would interpret those photos with some caution. Under-eye lighting, makeup, swelling immediately after treatment, and concurrent procedures (such as filler, fat transfer, laser treatments, or skin tightening) can dramatically affect the appearance of results. Social media and promotional photos often do not show how durable the improvement was or whether additional treatments were performed. In someone in their 50s with very deep hollows The most important question is what is causing the hollow: If it is primarily skin thinning, regenerative treatments like PRF may help somewhat. If it is primarily loss of volume and support, growth-factor injections alone are unlikely to create the kind of structural improvement that filler or fat repositioning can provide. If there is also fat pad bulging, adding volume indiscriminately can sometimes make the area look worse. My overall view I would consider microneedling with PRP/PRF to have a more established safety profile than injecting PDGF directly into the tear trough. I would be much more cautious about injected PDGF under the eyes because the published evidence is still relatively limited, and the lower eyelid is not an area where I would recommend experimenting with a poorly studied injectable simply because the before-and-after photos look impressive. For patients with significant congenital or age-related hollowness, I generally find that the most predictable non-surgical improvements come from carefully selected midface support, conservative tear trough filler in appropriate candidates, or regenerative treatments used as an adjunct for skin quality rather than as the primary volumizing treatment. So, to answer your question directly: PDGF injection under the eyes is not clearly established as unsafe, but it is also not well established as a proven, widely accepted, evidence-based treatment for deep tear trough hollows. The fact that multiple experienced providers in your area are declining to perform it is something I would view as a sign to proceed cautiously rather than as evidence that you simply haven’t found the right injector yet.
