PRF vs Filler Under Eyes
PRF treats the skin. Filler treats the hollow. PRF is made from your own blood, spun in a centrifuge and injected to improve texture and crepiness. Hyaluronic acid filler is a gel that fills the dip from the day it goes in. Only four fillers are approved for this exact spot, and PRF is not approved here at all. The other big difference: filler can be dissolved, and PRF cannot.
At a glance

HA filler
One small syringe, then a review A hyaluronic acid gel is injected into the hollow. Most people have one small syringe or less. You come back for a check a couple of weeks later.
Side by side
The differences that matter
What you actually do
PRF (Platelet-Rich Fibrin)
A blood draw, then a series of visits
Blood is drawn from your arm and spun in a centrifuge. The concentrate is injected under the eye. Nothing man-made is left behind. Most people need a series of visits, not one.
HA filler
One small syringe, then a review
A hyaluronic acid gel is injected into the hollow. Most people have one small syringe or less. You come back for a check a couple of weeks later.
What it actually changes
PRF (Platelet-Rich Fibrin)
Skin quality, not volume
It works on texture, crepiness and fine lines. It is not a volume treatment. That is the mismatch when the real complaint is a hollow. A review of 14 studies around the eye linked PRF to better texture and fewer wrinkles.
HA filler
The hollow itself
The gel fills the space under the eye at once. It does nothing for pigment or thin skin. A shadow here can come from pigment, from thin skin or from where the fat pads sit, and filling only helps one of those.
How long it lasts
PRF (Platelet-Rich Fibrin)
Often fading by six months
The improvement often fades by six months. So the fair way to think about PRF is a series you repeat.
HA filler
About a year in the trials
In one study, the improvement was still there at 18 months. Most people go back at about a year.
If you want it undone
PRF (Platelet-Rich Fibrin)
No reversal agent
There is nothing to dissolve. PRF is your own tissue, and your body clears it on its own.
HA filler
Dissolved in minutes to hours
An enzyme called hyaluronidase breaks the gel down. This is the clearest practical advantage of hyaluronic acid under the eyes.
The downside
PRF (Platelet-Rich Fibrin)
A blood draw, bruising, repeat visits
Being made from your own blood is not the same as being risk free. Expect a needle in the arm, bruising, and appointments that keep coming back.
HA filler
Blue-grey shadow, lasting puffiness
Gel placed too close to the surface can scatter light and look blue-grey. This is called the Tyndall effect. The area also drains poorly, so swelling over the cheekbone can last months. Neither problem has a reliable published rate.
Cost
PRF (Platelet-Rich Fibrin)
Paid per visit, and it is a series
Price the whole series, not one visit. The improvement often fades by six months.
HA filler
Paid by the syringe
Most people have one small syringe or less, then repeat at about a year.
The at-home version
PRF (Platelet-Rich Fibrin)
There is none
Nothing sold in a shop draws blood, spins it and puts it back. Caffeine creams and cooling rollers take down puffiness for a few hours only.
HA filler
Serums are not filler
A serum sits on the surface and holds water there. Filler goes several millimetres down, where it can hold a hollow open. A cream cannot reach that depth.
Who tends to be happy with it
PRF (Platelet-Rich Fibrin)
- Best for — Someone whose complaint is thin, crepey skin rather than a hollow, or who has had a filler problem before.
- The mindset — A short series of visits for a modest change in skin quality, repeated over time.
HA filler
- Best for — Someone with a real hollow who wants it filled, and who values being able to have it removed.
- The mindset — One small syringe or less, checked a couple of weeks later, dissolvable if it is wrong.

Common questions
Questions Patients Ask
Is PRF better than filler under the eyes?
Nobody knows, because no randomised trial has compared them. What differs is the evidence behind each. Four hyaluronic acid fillers hold an FDA approval for the infraorbital hollow, each supported by a randomised, controlled, multicentre trial with around a year of follow-up. PRF's under-eye evidence is case series, small cohorts and technique papers, with no standard preparation and improvements that often faded by six months.
Which hyaluronic acid fillers are actually approved for the under-eye?
Four. Juvederm Volbella XC was approved on 28 May 2021 for the improvement of infraorbital hollowing in adults over 21. Restylane Eyelight followed on 8 May 2023, Belotero Balance (+) Lidocaine on 27 September 2023, and RHA Redensity Eye and Eye Lido on 12 May 2026. Any other filler used in this area is being used off-label, which is legal and common.
Can PRF be dissolved if I don't like it?
No, but it does not need to be in the same way. Hyaluronidase only breaks down hyaluronic acid, so it has no effect on a blood-derived product. PRF is your own tissue and is resorbed over time. Hyaluronic acid filler, by contrast, can be dissolved deliberately within minutes to hours - which is the main reason some people choose it for this area.
Is PRF safer because it comes from my own blood?
Being autologous removes the question of reacting to a foreign material. It does not remove the risk that comes from putting a needle near the arteries that supply the eye. Platelet-rich plasma appears in the published filler blindness case reviews, inside a small "other" category. Any injection in this area carries that risk.
What is the Tyndall effect?
It is the blue-grey shadow that appears when hyaluronic acid gel sits too close to the surface and scatters blue light through the skin. It shows up most under the eyes because the skin there is the thinnest on the body. It is commonly reported, no reliable incidence figure has been published, and it is usually treated by dissolving the filler with hyaluronidase.
How long does under-eye filler last?
The approved products were followed for about a year in their trials. In practice it often lasts longer: a retrospective study of 155 patients treated with a mean of 0.45 mL per side found improvement still present at 18 months. Small MRI series have detected hyaluronic acid years after injection, though a signal on a scan is not the same as a visible result.
How many PRF sessions will I need?
The published studies typically use a short series. In the periorbital platelet-rich plasma literature the average was three treatments, with a range of one to eight, spaced a few weeks apart. Because improvements often faded by six months in the systematic review, maintenance sessions are part of the picture.
Why does the FDA warn about the periorbital area if fillers are approved for it?
Both things are true. The FDA's general dermal filler page, last updated in 2023, lists the periorbital area among regions it recommends against injecting, and that page has not been reworded since the product-specific approvals were granted. Four named products now hold an infraorbital indication. Fillers without that indication used here are off-label.
Safety to keep in mind
Four hyaluronic acid fillers carry a US FDA approval for the infraorbital hollow. Juvederm Volbella XC, approved 28 May 2021, for "the improvement of infraorbital hollowing in adults over the age of 21." Restylane Eyelight, 8 May 2023. Belotero Balance (+) Lidocaine, 27 September 2023, for "volume augmentation for the improvement of the infraorbital hollow in adults over the age of 21." RHA Redensity Eye and Eye Lido, 12 May 2026, for the infraorbital region in adults aged 22 or older. Each reached that point through a randomised, controlled, multicentre trial with about a year of follow-up. Any filler without that indication is being used off-label here.
PRF has no FDA approval for any facial cosmetic use. The centrifuges and kits used to prepare platelet-rich plasma and platelet-rich fibrin are cleared through the 510(k) route for preparing platelet concentrates. Clearance of a preparation device is not approval of a treatment, so injecting it into the face proceeds as off-label practice.
The FDA's general dermal filler page still recommends against injecting the periorbital area. It has not been reworded since these approvals. Both statements are true at once: four products hold this indication, and any filler without it is off-label here.
Trial figures. Volbella XC's under-eye trial randomised 140 people, 105 treated and 35 untreated; 83% responded at month 3 against 16% of the untreated group, and 73% still responded at month 12. Belotero Balance (+) reported 81% at week 8 and 81% at week 48. The 18-month figure comes from a study of 155 patients treated with an average of 0.45 mL per side. Each product used its own manufacturer-developed rating scale in its own separate trial, so those numbers cannot be lined up against each other. Galderma reported no cases of Tyndall effect in the Restylane Eyelight phase 3 study, which is the manufacturer's statement about its own product.
