Question 1

Am I a good candidate for under-eye filler?

Accepted Answer

The best candidates have volume loss (hollowing) in the tear trough without significant skin laxity or festoons (chronic eyelid swelling). Pigmentary dark circles, vascular dark circles, and festoons typically don't respond to filler, and filler can make festoons worse.

Question 2

What is the Tyndall effect?

Accepted Answer

When HA filler is placed too superficially under thin under-eye skin, it refracts light and appears blue. Prevention requires deep supraperiosteal placement by an experienced injector. If you develop a blue tint, hyaluronidase can dissolve the filler.

Question 3

How long does under-eye filler last?

Accepted Answer

HA filler in the tear trough often lasts 1-3 years, sometimes longer. Some patients metabolize filler faster, while others see persistence beyond expected duration. We do not recommend permanent fillers in this area.

Question 4

Should I use a cannula or needle?

Accepted Answer

Many experienced injectors prefer a blunt cannula in the tear trough, it reduces the risk of vascular injury and bruising compared to sharp needles. The choice ultimately depends on injector experience and anatomy.

Question 5

Is under eye filler safe?

Accepted Answer

In experienced hands, on the right candidate, with conservative technique, under-eye filler is generally safe and fully reversible. The area is unforgiving, though: risks include bruising, swelling, lumpiness, the bluish Tyndall effect, migration, and, rarely but seriously, vascular occlusion, which in the periorbital area can in rare cases threaten vision. Safety here comes down to a qualified, experienced injector using small amounts, placing deep, selecting candidates carefully, and keeping emergency protocols on hand.

Question 6

How much is under eye filler?

Accepted Answer

Pricing varies widely by region and injector experience, typically running several hundred to over a thousand dollars per syringe, and the tear trough often needs only a small amount. The most expensive under-eye filler is a cheap one placed badly: correcting puffiness, discoloration, or migration costs more in money and distress than choosing an experienced injector at the outset. Treat price as a secondary factor here, well behind skill.

Question 7

What is the best filler for under eyes?

Accepted Answer

The best under-eye filler is a hyaluronic acid product, because it can be dissolved if anything goes wrong. Experienced injectors tend to favor softer, lower-water HA fillers that resist puffiness in this area. The specific brand matters far less than reversibility and the injector's skill, which is why we advise against any semi-permanent or permanent filler under the eyes, where complications are harder to treat and linger.

Question 8

Can filler be dissolved?

Accepted Answer

HA filler can be dissolved with hyaluronidase (an enzyme). This is used for unwanted results, migration, lumps, or vascular emergencies. The dissolution itself is generally safe but should be done by an experienced provider.

Question 9

How do you fix under-eye hollows without filler?

Accepted Answer

If you would rather avoid injectables, several options address the under-eye depending on the cause: PRP and microneedling gradually thicken and improve thin, crepey skin; restoring mid-face (cheek) volume can soften a tear-trough shadow from below; brightening treatments fade pigmented dark circles; and lower-eyelid surgery (blepharoplasty) is the answer for protruding fat bags, which filler cannot fix and can worsen. Good skin care and sun protection support all of these.

Question 10

What about non-HA fillers in the under-eye area?

Accepted Answer

We strongly advise against semi-permanent or permanent fillers (PMMA, calcium hydroxylapatite, polylactic acid) in the under-eye area. Complications are more difficult to treat and persist longer.
