What should you know about hollow under eye treatment?

A tear trough is a groove between the lower eyelid and cheek. It can look deeper when the face has less volume, the eyelid-cheek boundary is naturally pronounced, or the skin casts a shadow. Dark circles and hollows can appear together, but pigment or visible blood vessels will not be corrected simply by adding volume. Puffiness, lax skin and facial asymmetry also affect the result. See [Tear Trough Hollows](/conditions/tear-trough-hollows/) and [Dark Circles](/symptoms/dark-circles/) for related concerns.

A qualified clinician should examine the lower eyelids and cheeks at rest and while smiling. Under-eye filler is injected in selected layers and may suit a mild hollow when the skin and surrounding tissues are appropriate; swelling, bruising, lumpiness and bluish discoloration are possible. Eyelid surgery can address excess skin or fat in people whose main concern is structural change. Fat transfer uses fat from another body area and has its own healing and volume-variation considerations. Discuss [Under-Eye Filler](/treatments/injectables/tear-trough-filler/), [Eyelid Surgery](/treatments/surgical-dermatology/blepharoplasty/) and [Fat Transfer](/treatments/surgical-dermatology/fat-grafting/).

Arrange prompt medical review for new one-sided swelling, pain, redness, discharge, vision change or a rapidly changing lump. After an injection or procedure, urgent assessment is needed for severe pain, pale or mottled skin, sudden visual symptoms, marked swelling or weakness around the eye. These signs can indicate a complication that needs timely treatment.

Ask which feature is creating the hollow, whether pigmentation or puffiness also needs treatment, what product or technique is proposed, how swelling will be managed, and what warning signs should prompt a call.
