Can under eye injection of platelet rich plasma improve hollowing and can this type of injection cause vascular occlusion?

PRP Can definitely improve undereye hollowing. it will all depend on the quality of "spinner" your clinic uses. using only PRP will reduce the risk of vascular occlusion.

Hi @Whs88wr! Although PRP injections are one of the safer undereye injections to get, no aesthetic procedure is without risk. It is extremely rare, but as with filler or any undereye injectable, if administered incorrectly, PRP injections can cause blindness, infection, or internal bleeding.

A vascular occlusion is a very rare side effect that occurs when an injectable is injected either into an artery or around an artery so blood flow is stopped – very, very rarely this can cause blurry vision or sudden permanent blindness.
To date however, there has only been one reported case of blindness related to PRP in the literature that I have seen.* Dermal fillers tend to have a higher risk of blindness (Botulinum Toxin less so), and these types of incidents usually have to do with the experience and competenceof the injector.
Again, this is exceedingly rare, but there were 100 reports of vision loss globally due to dermal fillers in 2015* and your doctor should inform you of this very unlikelyrisk before the procedure.
PRP is generally extremely safe and uses the body’s own growth factors (drawn from your blood and spun through a centrifuge), to help promote healing and rejuvenation.PRP also encourages collagen production, which may assist in plumping out dark hollows.Laser and micro needling are other possible options
