What should you know about dermal filler tear trough?

A tear trough is a depression running from the inner lower eyelid towards the cheek. Shadowing can come from the hollow itself, pigmentation, thin skin, fluid retention, or a nearby bulge. [Tear Trough Hollows](/conditions/tear-trough-hollows/) describe the structural concern; [Dark Circles](/symptoms/dark-circles/) can have other causes that filler will not correct.

A clinician may examine your eyes at rest and while smiling, check skin thickness and puffiness, and review previous filler. Hyaluronic acid is one material used in this area; see [Hyaluronic Acid Filler](/materials/hyaluronic-acid-filler/) for background.

Have the area assessed by an experienced medical injector who can explain whether the hollow, pigmentation, laxity, or swelling is the dominant issue. Share information about allergies, medicines, eye conditions, and prior procedures. A conservative plan may be preferable around the lower eyelid, where overfilling can make puffiness or unevenness more noticeable.

Temporary redness, swelling, bruising, tenderness, or small areas of firmness may follow treatment. Do not rub the area or apply pressure unless instructed. Arrange review if the result is uneven or if swelling persists beyond the timeframe your clinician discussed. The dedicated treatment page is [Under-Eye Filler](/treatments/injectables/tear-trough-filler/).

Contact the clinic promptly for increasing pain, marked swelling, unusual skin colour, or a blister. Seek urgent care for any new visual disturbance, severe headache, weakness, confusion, or difficulty speaking after an injection. Do not wait for a routine review when vision is affected.

Ask what is causing the shadow, whether filler could worsen puffiness, which product and layer are planned, how complications would be managed, and when you should be reviewed. Ask what non-filler options fit your concern if the hollow is not the main cause.
