Tear Trough Correction: Why Most Bad Results Come From Patient Selection
The tear trough is the region where injectors most often discover that technical skill is not the limiting factor. The procedure itself is not especially difficult. Choosing who should have it is, and the majority of unhappy infraorbital outcomes were decided before the needle was picked up.
What the hollow actually is
The shadow patients point to is rarely a single problem. It may be a true tear trough — a ligamentous attachment tethering the skin over a relative depression — or the visible edge of an orbital fat pad, or descent of the midface leaving the lid–cheek junction exposed, or pigmentation and thin skin producing darkness with no volume component at all.
These look similar in a mirror and respond completely differently. Filler placed under a fat pad that is protruding will make it more obvious. Filler placed where the darkness is pigmentary changes nothing and leaves the patient wondering what they paid for. Filler placed in a patient with poor lymphatic drainage produces persistent puffiness that can last months.
The single most valuable habit in this region is deciding which of these you are looking at before agreeing to treat, and saying so out loud.
Who should not be treated
Patients with significant orbital fat prolapse, marked skin laxity, existing fluid retention or a history of morning puffiness, and those whose darkness is pigmentary rather than structural, are all likely to be disappointed. So is anyone whose expectation is that the area will look "rested" when the underlying issue is descent of the whole midface.
Several of these are better served by treating the cheek instead — restoring support below the hollow rather than filling the hollow itself often produces a better result with less risk. Others are better served by a surgical opinion, or by nothing at all.
The anatomy that makes this risky
The infraorbital region carries vessels — including the angular and infraorbital systems — with connections toward the ophthalmic circulation, which is why vascular events here can involve vision. The skin is the thinnest on the face, so anything placed too superficially shows: as a visible ridge, or as the bluish discolouration produced when light scatters through gel under thin skin [2].
The area also has limited capacity to disperse product. Material that would settle unnoticed in a cheek stays visible here, and hyaluronic acid's tendency to draw water is more consequential in a region already prone to fluid accumulation.
Conservative principles
Precise planes, products and quantities belong in supervised training and in your clinic's protocol rather than in an article. The principles that hold generally:
- Superficial placement is what produces the visible failures here — the ridge, the bluish discolouration, the lump that will not settle. That is why depth is taught in this region, and also why it is taught under supervision rather than read: the infraorbital foramen and its vessels sit in the deeper plane, and deeper is only safer in hands that know where that foramen is on this patient.
- Undertreat, deliberately, and review before adding anything. There is no urgency in this region, and a second appointment is cheaper than dissolving.
- Consider supporting the midface first and reassessing the hollow afterwards.
- Prefer a blunt cannula and few entry points. Bruising here is conspicuous and slow to fade.
- Photograph before treatment, in consistent light. Patients reliably misremember the starting point.
Setting the timeline
Swelling in this region is frequently worse at two days than immediately, and can take several weeks to settle fully. A patient told this in advance experiences it as expected; a patient told nothing experiences it as a botched result and often demands dissolving of a result that had not yet arrived.
Make the review appointment part of the treatment plan rather than something offered if there is a problem.
When it goes wrong
Most infraorbital complications are aesthetic rather than dangerous — a ridge, a blue tinge, persistent puffiness — and are correctable with hyaluronidase, though correction carries its own risk of overshooting into a hollow that takes months to recover [1].
The dangerous ones are vascular, and they follow the same rules as anywhere else on the face: disproportionate pain, blanching, mottling that does not blanch, and any visual symptom mean stop, treat and refer immediately. As with the nose, this region should not be treated by anyone who is not fully prepared for that scenario [3].
The professional point
Injectors who are good at tear troughs are usually the ones who decline the most of them. The skill being sold is not the placement; it is the assessment that decides whether placement will help at all.
