If the area under your eyes looks hollow, shadowed, or tired, you likely have what are commonly called tear troughs — under-eye hollows. They’re a loss of volume in the groove between the lower eyelid and cheek, and despite the “tired” look, they’re driven mostly by genetics and aging rather than sleep.
If the area under your eyes looks hollow, shadowed, or tired, you likely have what are commonly called tear troughs — under-eye hollows. They’re a loss of volume in the groove between the lower eyelid and cheek, and despite the “tired” look, they’re driven mostly by genetics and aging rather than sleep. This guide explains what causes under-eye hollows, how they differ from dark circles, how tear trough filler works, what it costs, the risks, and the alternatives.
Several factors combine. The biggest are genetics and the basic anatomy of the eye area — many people develop tear troughs in their twenties regardless of lifestyle. With age, the skin loses collagen and elastin and the fat pads that cushion the face break down, deepening the hollow. The skin under the eyes is also the thinnest on the face, so any volume loss — and the blood vessels beneath — show through readily. Sun exposure, dehydration, and weight loss can make hollows more noticeable, but they’re rarely the root cause.
This distinction decides the right treatment. Hollowing is a loss of volume that creates a depression and shadow, while dark circles can come from pigmentation, visible blood vessels through thin skin, or the shadow cast by hollowing itself. The two often coexist. Filler treats the hollow (and the shadow it casts), but it won’t fix true pigment-based dark circles — which is why a careful assessment matters.
Tear trough filler uses an injectable hyaluronic acid gel placed in the hollow to restore volume, smoothing the transition between the lower eyelid and cheek so shadows soften and the area looks refreshed. Results are immediate, the treatment takes about 15–30 minutes with numbing, and — because the under-eye area barely moves — it lasts notably longer here than in mobile areas like the lips. This is the same family of fillers covered on the dermal fillers hub.
Injectors favor cohesive, structured HA fillers that resist puffiness in this delicate spot. Restylane Eyelight is the first HA filler FDA-approved specifically for under-eye hollows, and Restylane products are often preferred here for their lower puffiness risk. Juvederm Volbella is also used. The right pick depends on your anatomy — compare the two leading lines in Juvederm vs Restylane.
Longer than most areas. Because there’s so little movement under the eyes, filler here typically lasts 12 to 18 months — some patients go a full year or more between touch-ups. That’s well beyond lip filler and far longer than Botox’s 3–4 months, since Botox treats movement lines, not volume loss.
Under-eye filler is priced per syringe and sits at the higher end of filler pricing — roughly $700 to $1,500+ per syringe, with one to two syringes typical. It can cost more than filler elsewhere, but it also lasts longer, so the yearly cost often evens out. It isn’t covered by insurance. For how this compares with neuromodulator pricing, see the Botox cost guide and Botox vs fillers.
The under-eye is the most delicate filler area, so technique matters more here than almost anywhere. Common, temporary effects include swelling, bruising, and occasional lumps that can be massaged or dissolved. Over-treatment can cause lasting puffiness or a bluish tinge (the Tyndall effect). The rare but serious risk — shared with all filler — is accidental injection into a blood vessel, which can, very rarely, cause vision problems. HA’s reversibility (dissolvable with hyaluronidase) is an important safety net. The risk profile is different from Botox’s side effects. Expect full results in 1–2 weeks once swelling settles; avoid intense activity for 24–48 hours and sleeping face-down.
Not entirely — the main drivers are genetics and aging — but you can slow how fast they deepen. Daily broad-spectrum sunscreen protects the thin under-eye skin from collagen-degrading UV, and good hydration, sleep, and managing allergies (which can darken and puff the area) all help. A nightly eye cream with peptides or a gentle retinoid can modestly improve skin quality over time, and avoiding aggressive rubbing protects the delicate tissue. None of this reverses an established hollow — that needs an in-office treatment — but it keeps the area looking its best for longer.
Tear trough filler works best for mild-to-moderate hollowing with good skin quality. It’s not ideal if you have very deep hollows, excess lower-eyelid skin or fat, or very dark pigment-based circles — those may be better served by skin boosters, mid-face volumizing, energy devices, or lower-eyelid surgery (blepharoplasty). A doctor-led assessment determines whether filler is the safest, most natural option for you. For movement-related concerns elsewhere, like forehead wrinkles, a neuromodulator such as Botox or Dysport is the right tool — see Botox vs Dysport.
After a consultation to confirm filler is right for your hollows, the injector numbs the area and places a small amount of HA gel deep against the bone, often using a blunt-tipped cannula rather than a needle to reduce bruising and lower the vascular risk. The treatment takes about 15–30 minutes, and they’ll add product gradually — conservative dosing is safest here. You’ll notice improvement immediately, with swelling or minor bruising settling over a few days and the final result at one to two weeks. Use ice for the first 48 hours, avoid intense exercise for a day or two, and don’t sleep face-down.
Given the delicacy and the rare-but-serious risks, this is not the area to bargain-hunt. Choose a board-certified dermatologist or plastic surgeon, or a highly experienced injector under medical supervision, who treats tear troughs regularly, uses an appropriate FDA-approved HA filler, often works with a blunt cannula, and keeps reversal enzyme on hand.
