Under-eye hollows and dark circles: causes and treatment
What causes it
Three different things produce a tired-looking under-eye, and they need completely different answers — which is why this area is so commonly mistreated.
The first is volume loss: the fat pad under the eye thins and the bone beneath it recedes, creating a groove that catches shadow. The second is pigment — genuine darkening of the skin, common in some skin tones and worsened by sun exposure or rubbing. The third is fluid and fat protrusion: a puffy lower lid where fat has pushed forward through weakened tissue.
A shadow from hollowing looks darker in overhead light and lifts when you tilt your head back. Pigment does not change with light. That single test tells you more than most consultations.
Treatment options
| Cause | What helps | Results appear | Lasts | Where |
|---|---|---|---|---|
Volume loss / tear trough groove | Hyaluronic acid dermal filler, placed conservatively. | Immediate, settling over 2 weeks | 6 months – 2 years | At Beauty Factory SD |
Mid-face descent contributing to the groove | Cheek filler to restore support above the hollow. | Immediate | 6 months – 2 years | At Beauty Factory SD |
Skin quality and fine crepiness | Microneedling to build collagen in thin under-eye skin. | Weeks, over a course | Maintained with repeat sessions | At Beauty Factory SD |
True pigmentation | Topical or light-based pigment treatment. Filler does nothing for this. | Weeks to months | Varies | Not offered here |
Protruding fat pads / eye bags | Lower blepharoplasty — surgery. | After healing | Years | Not offered here |
What we would recommend
If your hollow lifts when you tilt your head back, it is a shadow cast by a groove, and a hyaluronic acid filler placed carefully in the tear trough is the treatment that addresses it. Often the better result comes from supporting the cheek just below rather than filling the groove directly.
This is a genuinely technical area — the skin is the thinnest on the body, the tissue holds fluid readily, and over-filling is visible and slow to resolve. Conservative placement with a plan to review and add is the right approach; a large single correction is not.
If your under-eye is puffy rather than hollow, filler will make it look worse. We will say so.
What it won't fix
Filler will not lighten a dark circle caused by pigment. It adds volume beneath the skin; it does not change the colour of the skin. If the darkness is unchanged when you tilt your head back, filler is not your treatment.
It will not remove eye bags. Herniated fat pads are a surgical problem, and injecting around them adds weight to an area that is already protruding.
It will not fix under-eye appearance driven by sleep, allergy, thyroid function or fluid retention — those change week to week, and a treatment placed at a bad moment gets judged against a good one.
It will also not last as reliably here as elsewhere. This is a low-movement area, so filler often persists longer than the label suggests — which is an argument for less product, not more.
What we use for under-eye hollows
Common questions
How do I tell whether my dark circles are shadows or pigment?
Tilt your head back under an overhead light. A shadow cast by a hollow will visibly lift; true pigmentation will not change. Shadows respond to filler, pigment does not.
Is filler under the eyes safe?
Our products are FDA-approved and the procedure is minimally invasive, but the under-eye is one of the more technical areas on the face and outcome depends heavily on placement and on conservative dosing. It should be assessed and performed by an experienced injector.
How long does under-eye filler last?
Typically 6 months to 2 years, depending on product and individual skin. Because the area moves relatively little, filler here often persists at the longer end of that range.
Will filler help if I have eye bags?
No. Protruding fat pads are a surgical concern, and adding filler to an area that is already pushing forward generally makes it more noticeable, not less.
