Dark circles and under-eye hollows are not one condition with one solution. They have three distinct causes: shadow from volume loss, pigmentation within the skin, and visible blue-purple vasculature beneath thin skin. Tired-looking eyes are extremely common and usually harmless, although sudden puffiness or swelling around one eye should be reviewed medically. Treatment only works when the cause is correctly identified, which is why polynucleotide treatments suit one patient and do nothing for another.
This is the reason so many eye creams disappoint. A cream cannot fill a hollow, and it cannot lighten a shadow that is being cast by anatomy rather than by pigment.
Where thin, crepey skin is the dominant issue, regenerative approaches work on tissue quality rather than volume. PRP therapy uses growth factors from your own blood to stimulate collagen in a notoriously delicate area.
Dehydrated, dull skin around the eye responds to hydration at the dermal level, and skin boosters improve elasticity and light reflection without adding structural volume.
True structural hollowing, where the bone rim is visible, may require careful volume restoration, and conservative dermal fillers placed deeply and sparingly are the appropriate tool there.
Because the tear trough is one of the highest-risk areas of the face, treatment should only take place after a full assessment at a doctor-led medical aesthetics clinic.

The Three Causes of Under-Eye Shadowing
1. Structural Shadow
As the medial cheek fat descends and the orbital rim becomes more prominent, a groove forms between the lower eyelid and the cheek. This is the tear trough. What looks like a dark circle is actually a shadow cast by a change in surface contour.
A simple test: if the darkness reduces significantly when you tilt your head back or shine light directly upward onto the face, it is largely shadow.
2. Pigmentation
True periorbital hyperpigmentation is excess melanin in the skin itself. It is more common in patients with higher Fitzpatrick skin types, is often familial, and can be worsened by sun exposure, rubbing, and inflammatory conditions such as eczema.
The test here is stretching the skin gently. Pigment stays visible when stretched, whereas shadow flattens out.
3. Vascular Visibility
The skin under the eye is among the thinnest on the body. Where it thins further with age or is naturally very fine, the underlying venous plexus shows through as a blue or purple tint.
This type often worsens with poor sleep, dehydration, alcohol, salt intake, and nasal congestion, all of which affect venous flow.
Mixed Presentations
Most patients have a combination. Identifying the dominant contributor determines the treatment order, and treating the wrong component first is the usual reason results underwhelm.
Is Puffiness or Darkness Ever a Medical Concern?
- Common and cosmetic: gradual hollowing, familial pigmentation, mild morning puffiness.
- Temporary: fluid retention from salt, alcohol, poor sleep, allergy, or crying.
- Worth investigating medically: persistent swelling in one eye only, associated pain or vision change, rapidly progressive puffiness, or swelling accompanied by breathlessness or general oedema.
- Dermatological: eczema or contact dermatitis around the eye, which needs treating before any aesthetic intervention.
Iron deficiency, thyroid dysfunction, and chronic allergic rhinitis can all contribute to under-eye darkness. A doctor-led setting allows these to be considered rather than overlooked.
Treatment Options by Cause
For Structural Hollowing
- Deep, conservative filler placement onto bone beneath the orbicularis muscle, using low volumes.
- Mid-face volumisation to support the cheek rather than filling the trough directly, which is often safer and more natural.
- Assessment for fluid retention tendency, since some patients are poor candidates for filler in this area.
For Skin Quality and Thinning
- Polynucleotides to support fibroblast activity and tissue regeneration.
- PRP for autologous growth factor stimulation.
- Skin boosters for dermal hydration and elasticity.
- RF microneedling at conservative settings for collagen remodelling, where appropriate.
For Pigmentation
- Diligent daily sun protection, which is non-negotiable and the single most effective measure.
- Medical-grade topical agents such as retinoids, vitamin C, niacinamide, and tyrosinase inhibitors, used cautiously near the eye.
- Superficial chemical peels formulated for periorbital use.
- Treating the cause of rubbing, since chronic friction drives post-inflammatory pigmentation.
For Vascular Prominence
- Improving sleep, hydration, and salt intake.
- Managing nasal congestion and allergy.
- Thickening the overlying skin through regenerative treatment, which reduces visibility.
- Camouflage with colour-correcting cosmetics, which remains genuinely useful.
Comparison Summary
- Filler: immediate contour change, longest lasting, highest technical risk in this area.
- Polynucleotides and PRP: gradual quality improvement over a course, low risk, no volume change.
- Skin boosters: improved hydration and glow, subtle, needs maintenance.
- Topicals and sun protection: essential foundation for pigmentation, slow but cumulative.
- Surgery: the only option for significant fat herniation or excess skin.
Why the Tear Trough Demands Caution
The under-eye region contains major vessels in close proximity to the skin surface, and the tissue has limited capacity to accommodate volume.
- Vascular risk. The angular and infraorbital vessels run through this zone. Inadvertent intravascular injection carries a rare but serious risk to vision.
- Tyndall effect. Filler placed too superficially scatters light and produces a bluish-grey discolouration.
- Prolonged swelling. Hyaluronic acid attracts water, and in a region prone to fluid retention this can cause persistent puffiness.
- Product migration. Excess volume can spread and create lumpiness that is difficult to correct.
- Poor candidate selection. Patients with lax skin, malar oedema, or fat herniation frequently do worse with filler.
These are exactly the reasons this area should be treated only by experienced medical practitioners with a thorough understanding of facial anatomy and access to reversal agents where appropriate.
Myths About Under-Eye Treatment
Myth: dark circles are always caused by tiredness. Sleep affects vascular visibility and puffiness, but structural shadow and pigmentation are unaffected by how well you slept.
Myth: filler is the answer for all dark circles. Filler addresses contour only. Used on pigmentation or vascular darkness it adds risk without benefit.
Myth: eye creams can remove hollows. Topical products can improve hydration, barrier function, and pigmentation to a degree. They cannot alter facial volume or bone position.
Myth: more product gives a better result. In the tear trough the opposite is true. Small volumes placed accurately outperform larger volumes almost every time.
Myth: results are immediate and permanent. Regenerative treatments work over weeks to months, and filler results evolve as swelling settles. Nothing in this area is permanent, and maintenance is part of the plan.
Practical Habits That Genuinely Help
- Apply broad-spectrum sun protection around the eyes daily, all year.
- Wear sunglasses to reduce squinting and ultraviolet exposure.
- Sleep with your head slightly elevated if you wake puffy.
- Reduce salt and alcohol in the evening.
- Treat allergies and nasal congestion properly.
- Avoid rubbing or dragging the skin when removing make-up.
- Stay well hydrated and manage iron intake through diet, seeking medical advice if you suspect deficiency.

Frequently Asked Questions
How do I know whether my dark circles are shadow or pigment?
Gently stretch the skin under the eye in good light. Pigmentation remains clearly visible when stretched, whereas a shadow caused by contour will flatten out and largely disappear. A clinical assessment with standardised lighting confirms it more reliably.
Is tear trough filler safe?
It can be safe in appropriately selected patients when performed by an experienced medical practitioner using conservative volumes and deep placement. It carries higher risk than most facial areas, so candidate selection and technique matter enormously.
How many sessions of polynucleotides or PRP are needed?
These treatments typically require a course of several sessions spaced a few weeks apart, followed by periodic maintenance. Improvement is gradual because it depends on your own tissue remodelling rather than on added volume.
Can under-eye filler be dissolved?
Hyaluronic acid based products can be dissolved with an enzyme injection if the result is unsatisfactory or complications occur. This is one reason hyaluronic acid is generally preferred over permanent products in this region.
Will treating my under-eyes make me look younger overall?
It often makes a noticeable difference to how rested you appear, since the eyes carry much of the perception of fatigue. That said, the mid-face and cheek frequently contribute to under-eye shadowing, so the best plans consider the region as a whole.
Conclusion
Under-eye darkness comes from shadow, pigment, or visible vessels, and each requires a different treatment. Identifying the dominant cause before intervening is what separates a genuine improvement from wasted effort. Given the anatomical risks in this area, assessment and treatment by a medical professional is essential.
