The area under the eye generates more product spending per square centimetre than anywhere else on the body and delivers the least. That is not because the products are all bad. It is because four different problems present as a dark ring and only two of them are the kind of problem a cream can address.
Identifying which you have takes about a minute in front of a mirror and saves a great deal of money.
Section 01The four causes
| Cause | How to identify it | Responds to topical | What actually helps |
|---|---|---|---|
| Pigmentation | Brown tone, unchanged when you stretch the skin | Slowly, partially | Sunscreen, azelaic acid, retinoid, time |
| Vascular | Blue or purple tone, more visible when tired | Poorly | Sleep, and procedural options if it matters |
| Hollowing | A shadow that changes with the angle of light | No | Structural, nothing topical addresses it |
| Puffiness | Swelling worse on waking, improves through the day | No | Sleep position, salt, alcohol, allergy control |
The one minute self assessment
Total 00:30- 01
Look in a mirror in even, front on light00:10
Not overhead. Overhead lighting produces a shadow under the orbital rim in almost everyone and is why bathroom mirrors are so unflattering.
- 02
Gently stretch the skin sideways00:10
If the darkness stays, it is pigment in the skin. If it lightens, it is vascular or shadow.
- 03
Tilt your head under a light source00:10
If the darkness moves or changes with the angle, it is a shadow cast by hollowing rather than a colour in the skin.
- 04
Compare morning to eveningTwo days
Swelling that is worst on waking and better by midday is fluid. Darkness that is constant is not.
Section 02Pigmentation, the one that responds
Periorbital pigmentation is common, has a strong hereditary component, is more prominent in some skin tones, and is worsened by sun exposure and by rubbing. It is the only one of the four that responds meaningfully to a topical routine, and it responds slowly.
Pigmentation protocol
Total 32 weeks- 01
Sunscreen on the area dailyDaily
The most effective intervention available and the one people skip because sunscreen near the eye can sting. A mineral formulation or a dedicated stick applied on the orbital bone is the practical answer.
- 02
Stop rubbing your eyesBehavioural
Chronic rubbing, often from untreated hay fever or dry eye, causes pigmentation directly. If you rub your eyes daily, treating the reason is worth more than any product.
- 03
Add azelaic acid or a low strength retinoid, carefully01 night/week
On the orbital bone, not the eyelid. Start at one night a week and expect to stay there. Irritation in this area produces its own pigmentation, which is a real and counterproductive risk.
- 04
Assess at week thirty twoWeek 32
Pigmentation is the slowest thing in this publication to respond. Anything judged before six months has been judged too early.
Do not apply exfoliating acids, high strength retinoids or benzoyl peroxide close to the eye. The skin there is thin, the product migrates during the night, and irritation of the eyelid is genuinely unpleasant and can itself produce lasting pigmentation.
Section 03Vascular and hollowing, the two that do not
Blue or purple discolouration is blood in the vessels of the deeper tissue showing through thin overlying skin. Nothing you apply topically will make skin thicker to a degree that hides it. Caffeine containing eye products produce a brief vasoconstriction that some people notice and which lasts a short time. That is a cosmetic effect rather than a treatment.
Hollowing is a structural change: loss of volume in the tear trough with age, or an inherited anatomy. It produces a shadow, and shadows do not respond to creams. This is the point at which the discussion becomes a procedural one, and the questions to ask before pursuing that are in what to ask before any cosmetic procedure.
The darkness lightens when you stretch the skin and is blue or purple
Vascular. Sleep, hydration and reduced alcohol help marginally. Topical products do very little. Accept it, or investigate procedural options with a properly qualified clinician.
The darkness moves with the light angle
Shadow from hollowing. Structural. No topical addresses it and buying one is spending on the wrong problem.
Swelling on waking that resolves by midday
Fluid. Sleep with your head slightly elevated, reduce salt and alcohol in the evening, and consider whether untreated allergy is contributing.
Sudden onset swelling of one eye, or with pain or visual change
Not a cosmetic issue. Seek medical assessment.
Brown discolouration that does not change with stretching or light
Pigmentation. The protocol above applies and it takes six months.
Section 04Does eye cream do anything
An eye cream is a moisturiser formulated for a thinner, more reactive area, usually with fewer active ingredients and a lower fragrance load. That is a legitimate product category. What it is not is a treatment for any of the four causes above, except insofar as any moisturiser temporarily improves the appearance of fine lines by hydrating the surface.
- Fragrance freeThe area is thin, permeable and next to the eye. Fragrance here is a poor trade in every case.
- A texture that will not migrateLight products migrate into the eye overnight. A slightly heavier texture applied to the orbital bone stays where it is put.
- No claim to remove dark circlesNo topical does this for vascular or structural causes. A product making the claim without qualifying it is telling you something about the seller.
- Not a duplicate of your face moisturiser at four times the priceCompare the ingredient lists. If they are close, use the face moisturiser and spend the difference on sunscreen.
- Suitable for use under sunscreenBecause sunscreen in this area is the intervention with the most evidence behind it.
Section 05The unglamorous variables
- Sleep. Both the duration and, for puffiness, the position. Sleeping flat encourages overnight fluid accumulation; a slightly elevated head reduces it.
- Alcohol. Produces both fluid retention and vasodilation, which is why the morning after looks the way it does.
- Salt in the evening. Contributes to overnight fluid retention in some people.
- Allergy. Untreated hay fever or perennial rhinitis produces both congestion related discolouration and chronic rubbing. Treating it addresses a cause rather than a symptom.
- Sun exposure. The area is often missed entirely by sunscreen application, and UV drives pigmentation.
None of those are products, which is why they are rarely discussed alongside eye creams. They are also, between them, more effective than anything in the category. Related reading: the sunscreen protocol, azelaic acid, and the plateau decision tree.
