Under-Eye Hollows: Why They Form and How to Address Them

The hollow groove beneath the lower lid that creates persistent shadows and a tired appearance. Addressed with precision.

Aging & Volume

The tiredness isn't in your eyes. It's underneath them.

What It Is

Under-eye hollows are depressions that form in the tear trough area — the groove between the lower eyelid and the upper cheek. They create shadows that read as dark circles and give the eye area a sunken, tired quality that persists regardless of how much sleep a patient gets.

They're distinct from under-eye bags (which involve fat herniation forward) and from pigment-based dark circles (which involve melanin in the skin). Under-eye hollows are a structural concern that requires structural treatment.

Why Patients Seek Treatment

Patients with under-eye hollows almost universally describe the same experience: they always look tired, even when they're not. The shadow created by the hollow makes the eyes look sunken and gives the whole face a fatigued quality that affects how others perceive them in conversation and photographs.

UNDERSTANDING THE SCIENCE

Under-eye changes are structural, not superficial — and they start earlier than most expect.

What Causes It

Under-eye hollows develop from structural changes in the periorbital area.

Fat pad thinning: The sub-orbicularis oculi fat (SOOF) and the orbital fat beneath the lower eyelid thin with age. This deflates the under-eye area and creates a visible depression.

Orbital rim remodeling: The bone of the orbital rim widens and remodels over time, increasing the visual depth of the tear trough groove.

Skin thinning: The skin beneath the eye is among the thinnest on the body and becomes increasingly translucent with age, making the hollow and underlying vasculature more visible.

Cheek descent: As the mid-face descends, it pulls away from the lower lid, deepening the transition between the eye and the cheek.

Common Signs

Patients with under-eye hollows typically notice one or more of the following:

  • A sunken or shadowed appearance beneath the lower eyelid
  • Dark circles that persist regardless of sleep or hydration
  • A tired or unwell appearance even when fully rested
  • A visible groove or crease where the lower lid meets the cheek
  • A drawn quality to the eye area that has developed gradually
03

Why It Changes Over Time

In the 20s, the under-eye area is typically smooth with a seamless transition from the lower lid to the cheek. Most people have no structural hollowing at this stage.

Through the 30s, the first suggestion of a tear trough groove emerges as the orbital fat begins to thin. Most patients notice this as persistent shadows that don't resolve with sleep.

Through the 40s and beyond, the hollow deepens as fat pad thinning continues, the orbital rim remodels, and the cheek descends further from the lower lid. The combination creates a pronounced under-eye shadow that significantly ages the face.

How It's Commonly Addressed

Under-eye hollows require careful, technically precise treatment.

  • Mid-face Volumization: Restoring cheek and mid-face structure is almost always the first step. Lifting the surrounding tissue reduces the hollow and improves the lid-cheek transition without touching the delicate tear trough area directly.
  • Tear Trough Filler: When the hollow persists after mid-face treatment, precise hyaluronic acid placement in the tear trough groove itself can address the residual depression. Product selection is critical — soft, low-viscosity fillers minimize the risk of puffiness or discoloration.
  • PRP/PRF: Platelet-rich plasma injected beneath the eye can improve skin quality and thin skin texture in the periorbital area, complementing structural treatment.

We assess the whole mid-face before treating the tear trough directly.

At CAMI, tear trough treatment begins with the cheeks. Before placing anything near the eye, we assess whether restoring mid-face volume will improve the hollow without directly treating the tear trough. In many cases it does — and it's safer.

When we do treat the tear trough directly, we use the softest appropriate product, placed conservatively, in the correct tissue plane. The Tyndall effect — a bluish discoloration that results from filler placed too superficially — is a preventable complication that results from incorrect technique. We prioritize caution over volume in this area every time.
