Dermal fillers for sunken eyes: the upper-lid hollow most consults never check

When people search for dermal fillers for sunken eyes, they usually picture one thing: a syringe of hyaluronic acid placed under the lower lid to soften a dark groove. That is a real treatment and it works well in the right face. But in consultation the word sunken covers at least four different problems, and only one of them is the classic tear trough. The others sit above the crease, behind the eye, or in a bottle on the bathroom shelf.

The pattern we hear most often goes like this. Someone notices that their eyes look deeper set than they did a year or two ago. The upper lid crease seems higher, the space under the brow bone looks scooped out, and makeup settles into a shadow that was not there before. They book an under-eye filler appointment because that is the treatment everyone talks about, and the injector looks at the lower lid, which may be fine.

The original element in this piece is a six-step mirror check that sorts a sunken look into upper-lid hollow, lower tear trough, a whole-eye change that needs a doctor rather than an injector, or a medication effect. We have not seen these steps published together as one routing guide. Each step is drawn from how these conditions are described in the clinical literature cited below; the sequence and the meaning attached to each result are assembled here. It does not replace an exam. It tells you which exam to ask for.

Step one: the overhead light test. Stand under a single ceiling light, face a mirror, and look straight ahead with a relaxed face. Find the deepest shadow. If it sits between your open lid and your brow bone, you are looking at the upper eyelid sulcus. If it runs from the inner corner of the eye down and out along the top of the cheek, that is the tear trough, covered in detail in our guide to the tear trough.

Step two: count the creases. With your eyes open, look at the upper lid. A crease that has crept higher than it used to be, or a second fold that has appeared above the original one, is a common visible sign of upper-lid volume loss. The lower lid tells you nothing about this.

Step three: compare the two sides. Cover one eye with your hand, then the other, and compare photos taken straight on. A hollow that is much deeper on one side deserves a closer look. If that side is also the eye you put drops in, go straight to step four. If one whole eye seems to sit further back in the socket with no obvious reason, stop here. A globe that has moved backward, called enophthalmos, can follow an old fracture or certain sinus conditions, and it needs imaging and a physician, not filler.

Step four: the medicine cabinet audit. Check for prostaglandin glaucoma drops (bimatoprost, travoprost, latanoprost, tafluprost) and for any eyelash growth serum, including cosmetic ones. This is the step most consultations skip, and it matters more than anything else on this list.

Step five: the old photo test. Find a straight-on photo from five years ago and one from two years ago. A slow, even change on both sides fits aging or weight loss. A change that appeared over months, especially on one side or after starting a new product, points back to step four.

Step six: the stretch test. Place a fingertip at the outer corner of the lower lid and gently stretch the skin sideways. If the darkness fades as the skin flattens, it is partly a hollow or shadow. If the color stays put, it is pigment, and no filler will change it.

What the medicine cabinet can do to your eyelids. Prostaglandin analogue drops are a first-line glaucoma treatment, and their effect on the fat around the eye now has a name: prostaglandin-associated periorbitopathy. In a Japanese study of 250 glaucoma patients treated in one eye only, graders comparing photos saw upper-lid sulcus deepening in 60 percent of bimatoprost eyes, 50 percent of travoprost eyes, 24 percent of latanoprost eyes and 18 percent of tafluprost eyes. A separate Turkish series found sulcus deepening in 80 percent of bimatoprost users and noted that loss of the periorbital fat pad is usually the first sign to appear.

The quotable line here is simple: a substantial share of people on these drops develop a hollow that looks exactly like aging, and an injector who does not ask about eye drops will treat it as aging.

Lash serums deserve the same question. Oculoplastic surgeons writing in Aesthetic Surgery Journal graded manufacturer before and after photos of prostaglandin-containing lash lengtheners and found changes compatible with periorbitopathy, scoring well above serums without prostaglandins and false lashes. Their case patient developed upper-lid hollowing after ten months on a cosmetic serum, and it reversed about six months after she stopped. They also noted that the customer-facing ingredient list often does not mention prostaglandins at all.

That reversibility is the practical point. A serum hollow may fade on its own after stopping, so filling it first means paying to treat something that might resolve. Glaucoma drops are different: never stop or switch them yourself. Raise the change with your eye doctor, who can weigh whether another class of drop makes sense for your pressure control.

Dermal fillers for sunken eyes: what they can and cannot do above the crease. Filler in the upper eyelid sulcus is a real technique, but it is a narrower, more specialist procedure than tear trough work. The tissue is thin, small volumes go a long way, and lumps or a bluish tint show easily. When a sunken upper lid comes from prostaglandin use, aging, or an overly aggressive past blepharoplasty, some oculoplastic surgeons use small amounts of hyaluronic acid gel there, including a Beverly Hills case report in which sulcus filler was used to treat a deep hollow that kept knocking a patient's soft contact lens out of place.

What the studies do not tell you. A review of treatments for the sunken superior sulcus found twelve published reports covering 680 cases. Every one was a case series. There were no randomized trials, filler was used in only four of the reports, and about 7 percent of patients had a complication. Nobody has compared filler against fat grafting or surgery head to head in this area, and nobody has published how long upper-lid filler lasts in eyes that are still on prostaglandin drops. Anyone quoting you a precise longevity figure for this spot is extrapolating.

Safety matters too. A 2024 review of 365 newly published cases of vision loss after filler found the highest-risk sites were the nose, forehead and glabella, and the upper eyelid sits right alongside the forehead and glabella. The review also reported that only 6 percent of affected eyes recovered fully. That is a reason to choose an injector who works around the orbit routinely and can explain their plan for a vascular event before starting, not a reason to panic.

If the check points below the lid. When the deepest shadow is a true tear trough hollow, filler is a reasonable tool, and technique matters more than brand. Our pillar guide on cannula versus needle in the tear trough covers how placement changes risk. If weight has dropped recently, including on a GLP-1 medication, read our piece on timing under-eye filler during weight loss before booking, because a moving target is hard to fill well.

The takeaway. Sunken is a description, not a diagnosis. Before anyone fills anything, know which hollow you have, and bring a list of every eye drop and lash product you use to the consultation. If your injector never asks about either, that tells you something.
