What should you know about Restylane tear trough?

The tear trough is the transition between the lower eyelid and cheek. A hollow can create a shadow, but darkness may also come from pigment, visible vessels, thin skin, puffiness, or lighting. Filler can add structure beneath a hollow; it does not correct every cause of dark-looking under-eye skin.

The under-eye is a delicate, highly visible area. Swelling, bruising, tenderness, asymmetry, lumps, or a bluish hue can occur. Your clinician should explain whether the proposed product and placement suit your tissues and whether another approach is more appropriate.

Bring a list of medicines and supplements, mention previous injections or eye procedures, and report allergies, active irritation, or a history of unusual scarring. Ask how long early swelling may last and when the outcome should be reviewed.

After treatment, use only the care instructions provided for your case. Do not rub the area or add pressure unless advised. A review is useful if swelling settles unevenly or you remain concerned. Read about [Hyaluronic Acid Filler](/materials/hyaluronic-acid-filler/) and [Under-Eye Filler](/treatments/injectables/tear-trough-filler/) for related treatment information.

Tell the clinic about escalating pain, unusual firmness, spreading redness, increasing warmth, drainage, or a pale, grey, or mottled skin change. Get urgent medical help for any new visual disturbance, severe eye pain, marked headache, weakness, or speech difficulty after injection.

Ask whether the shadow is mainly caused by a hollow, what result is realistic for your anatomy, where the product would be placed, how swelling will be monitored, and what action to take if a complication is suspected. If darkness is the main concern, ask about [Dark Circles](/symptoms/dark-circles/) and [Tear Trough Hollows](/conditions/tear-trough-hollows/).
