A tear trough hollow is a groove running from the inner corner of the eye down and outwards towards the cheek. It forms where the thin lower-eyelid skin meets the thicker cheek, often because of inherited anatomy, loss of volume with age, or bulging fat above the groove that makes it look deeper. Treatment depends on the cause: filler suits some people, while others are better served by lower eyelid surgery with fat repositioning.
The anatomy behind the groove
Beneath the inner lower eyelid, the skin and muscle are tethered to the bony rim of the eye socket by a firm band of tissue. Above this line lies the eyelid; below it, the cheek with its deeper fat pads. Where these two zones meet, a natural depression can form.
The groove is often visible from a young age in people with a flatter cheek or deeper-set eyes. It may cast a shadow that looks like a dark circle even when the skin itself is not darker.
Why tear troughs deepen with time
- Volume loss: the cheek fat pads thin and descend, so the groove becomes more pronounced.
- Bone changes: the eye socket gradually widens with age, reducing support beneath the lid.
- Fat bulging: fat behind the lower lid can push forward, making the groove below it look deeper by contrast.
- Skin thinning: thinner skin reveals the shadow and underlying vessels more easily.
- Weight loss: significant weight loss can reduce facial volume and exaggerate hollows.
Hollow, bag or both?
Assessment starts with deciding whether the problem is a true hollow, a bulge above the groove, or a combination. In a pure hollow, there is little or no puffiness and the skin is of good quality. In a bag-and-groove pattern, the fat above the rim protrudes and the groove beneath it looks exaggerated.
This distinction matters because adding volume under a bag can make the whole area look fuller and puffier, while removing fat from above a hollow can deepen it further. Mr Nassab looks at the lower lid in different lighting and positions to judge which pattern applies.
Dermal filler for tear troughs
In carefully selected people with a genuine hollow, good skin tone and minimal fat bulging, a small amount of dermal filler placed deep, close to the bone, can soften the groove. Results are temporary and treatment needs repeating.
The tear trough is one of the more demanding areas to treat. Risks include lumps, persistent swelling, a bluish tinge if filler lies too superficially, and, very rarely, blockage of a blood vessel that can affect the skin or vision. Filler is avoided where there is marked puffiness or a tendency to fluid retention.
Surgical correction
Where fat bulging and a groove occur together, a lower blepharoplasty with fat repositioning is often more effective. Rather than removing the fat, the surgeon releases the tethering band and moves the fat down over the rim to fill the hollow. This can be done from inside the lower lid, with or without a small skin pinch beneath the lashes.
The aim is a smooth, continuous contour from lid to cheek. Lower blepharoplasty is priced from £7,500 and results typically last many years, although ageing continues.
Recovery after treatment
After filler, mild swelling and occasional bruising usually settle within a week or two. After lower eyelid surgery, bruising and swelling typically settle over two weeks, with most people back to desk work at around that point. The final contour becomes clear over three to six months. Cold compresses, head elevation and sun protection all help, and follow-up appointments allow progress to be checked.
Other factors worth addressing
Good sleep, managing allergies and reducing salt and alcohol will not remove a structural hollow, but can reduce puffiness that makes it look worse. Daily sun protection preserves skin quality. For some people, softening the cheek or improving skin texture has more effect than treating the trough itself.
Frequently Asked Questions
Are tear trough hollows the same as dark circles?
Not exactly. A hollow casts a shadow that can look like a dark circle, but true dark circles can also be caused by pigment or visible blood vessels.
How long does tear trough filler last?
It varies with the product and the individual, commonly several months to longer. It needs repeating to maintain the effect.
Is tear trough filler safe?
It carries specific risks, including rare but serious vascular complications, so it should only be done by an experienced medical practitioner after careful assessment.
Can surgery fix tear trough hollows?
Lower blepharoplasty with fat repositioning can soften the groove, particularly where bags and hollows occur together.
Why did filler make the under-eye area puffier?
Filler can attract water or sit too superficially, especially where there is fluid retention or bulging fat. An assessment can clarify options, which may include dissolving it.
