There are four kinds of dark circles, and they have almost nothing to do with each other. One is pigment. One is blood vessels. One is not darkness at all, it is a shadow. And one is skin so thin you are seeing what is underneath it. The eye cream aisle treats all four as the same problem, which is why almost none of it works.
You can figure out which type you have in about a minute, at a mirror, with a flashlight. Do that first. Everything after depends on it.
The three tests
Stand at a mirror in good light.
- The stretch test. Gently pull the skin under your eye sideways, flattening it. If the darkness stays exactly as dark, it is pigment. If it fades or disappears, it is vascular or structural.
- The flashlight test. Hold your phone light straight in front of your face, level with your eyes, pointing directly at you. If the dark circle vanishes when the shadow is filled in, it was never darkness. It was a shadow cast by a hollow or a bag. This is the single most useful test on this page and it takes five seconds.
- The morning test. Dramatically worse on bad sleep, after salt, or during allergy season, and better on a good week? That is vascular. Identical every single day for years? That is pigment or structure.
The four types of dark circles
1. Pigmented (brown)
Actual melanin in the skin under the eye. It reads brown or tan rather than blue, it does not blanch when you stretch the skin, and it does not care how much you slept.
Causes: genetics, and this one is strongly hereditary. It is far more common in South Asian, Middle Eastern, Mediterranean, Hispanic, and Black skin, and it often shows up in childhood or the teens. It is also caused by post-inflammatory pigment from years of eye rubbing, eczema, or allergies, and it is worsened by sun, because this is the part of the face people forget to protect.
What works: essentially the melasma playbook. Daily tinted mineral sunscreen with iron oxides, pigment-targeting topicals like azelaic acid or tranexamic acid, and gentle in-office treatment. It is slow and it is genuinely responsive.
What does not: filler. Injecting volume under brown pigment gives you a smoother, still-brown under-eye.
2. Vascular (blue, purple, or red)
Not pigment. You are seeing blood through skin. The veins and capillaries under the eye sit close to the surface, and the skin covering them is under half a millimeter thick, so deoxygenated blood shows through as blue or purple.
Causes: fatigue, dehydration, alcohol, nasal congestion, and allergies. Allergic congestion backs up venous drainage from the face, which is why allergy sufferers get the classic “allergic shiners” and why they get worse every spring.
What works: the boring things, and they genuinely work for this type. Sleep, water, treating your allergies properly, sleeping with your head elevated. Caffeine-containing eye products constrict vessels for a few hours, which is real but temporary. Vascular lasers can target persistent vessels. If a hollow is making them more visible, filler helps by adding a layer between the vessel and the light.
What does not: brightening and bleaching creams. There is no pigment to lighten.
3. Structural (a shadow, not a circle)
This is the one that fools the most people, and the flashlight test catches it instantly.
As the midface loses volume, a groove forms between the lower lid and the cheek, called the tear trough. Overhead light hits the ridge and the groove falls into shadow. There is no darkness in your skin. There is a topography problem, and light is doing what light does.
An under-eye bag does exactly the same thing from the opposite direction: the bulge casts a shadow beneath itself.
What works: changing the shape. Filler for a true hollow. Treating the bag, with Agnes RF or surgery, if the bag is what is casting the shadow.
What does not: every cream ever made. You cannot bleach a shadow.
4. Thin skin and mixed
Under-eye skin thins with age and sun damage, and as it thins it becomes more transparent, revealing the vessels and the dark orbicularis muscle beneath. It is really an amplifier: it makes the vascular type more visible, and it usually arrives alongside laxity.
What works: collagen stimulation. Retinoids used carefully, microneedling, energy-based treatment, and years of sunscreen.
And the honest note: most adults have two or three types at once. A pigmented base with a hollow casting a shadow over it is extremely common. That is why single-modality treatment so often produces a partial result and a disappointed patient.
Why your eye cream is not working
Not because it is a bad product. Because of what it is capable of.
An eye cream can, at best, do three things: hydrate the skin, mildly reduce fluid, and slowly influence pigment. That is the entire range.
Look at the list above and notice that two of the four types are not skin problems. Structural darkness is a light problem. Vascular darkness is a plumbing problem. No topical of any price will resolve either one, and both are common.
So when someone tells me they have spent $400 on eye creams and nothing worked, they usually are not wrong about the products. They are treating a shadow with a moisturizer.
Can dark circles be removed permanently?
It depends on the type, which by now will not surprise you.
- Structural: the most durable results in the group. Correcting a hollow or removing a bag changes the anatomy that was creating the shadow.
- Pigmented: improvable, sometimes dramatically, but it is a maintenance condition. Stop the sunscreen and it comes back.
- Vascular: manageable rather than curable. Anatomy is anatomy. Control the triggers and it is far less visible.
- Thin skin: improvable with collagen stimulation, and it is a long game.
Anyone advertising permanent removal of dark circles without asking which type you have is not making a medical claim. They are making a marketing one.
Dark circles in children
Parents ask about this often, and the answer is usually reassuring.
Dark circles in kids are most commonly allergic shiners: venous congestion from allergic rhinitis. They come with a stuffy nose, a persistent throat-clearing habit, mouth breathing, and a crease across the bridge of the nose from pushing it upward. Treat the allergies and the circles improve.
The second common cause is inherited pigmentation, which is benign.
Worth a pediatrician visit if the circles appear suddenly, come with fatigue or bruising elsewhere, or are only on one side. Those are different conversations.
What actually helps, starting tonight
- Do the flashlight test. If your circles disappear under direct light, stop shopping for creams. You need volume, not pigment control.
- Treat your allergies for real. Underrated, free-ish, and it fixes the vascular component in a lot of people.
- Sleep with your head elevated. One extra pillow.
- Wear sunscreen under your eyes. Almost nobody does. It is the only prevention that exists for the pigmented and thin-skin types.
- Stop rubbing. Every rub is micro-inflammation, and inflammation makes pigment.
- Get the diagnosis before you spend. The most common way to waste money on under-eyes is to buy a real solution to somebody else’s problem.

Frequently asked questions
What are the types of dark circles?
Four: pigmented (excess melanin, reads brown), vascular (blood vessels showing through thin skin, reads blue or purple), structural (a shadow cast by a tear trough hollow or an under-eye bag), and thin skin. Most people have more than one at the same time.
How do I know which type of dark circles I have?
Stretch the skin gently: if the darkness stays, it is pigment; if it fades, it is vascular or structural. Shine a light directly at your face from the front: if the circle disappears, it is a shadow, not darkness. If it varies with sleep and allergies, it is vascular.
Can dark circles be removed permanently?
It depends on the type. Structural darkness gives the most durable results, since correcting a hollow or a bag changes the anatomy causing the shadow. Pigmented circles improve but need maintenance. Vascular circles are managed rather than cured.
Why doesn’t eye cream work on my dark circles?
Eye cream can hydrate, mildly reduce fluid, and slowly influence pigment. Two of the four types of dark circles are not skin problems at all: structural darkness is a shadow and vascular darkness is blood showing through. No topical resolves either.
What causes dark circles under the eyes?
Genetics, allergies and nasal congestion, sun exposure, eye rubbing, loss of facial volume creating a tear trough hollow, under-eye bags casting a shadow, thinning skin with age, and fatigue or dehydration. Most people have several of these at once.
Do fillers get rid of dark circles?
Filler works for structural darkness, where a hollow is casting a shadow, and can help vascular circles by adding a layer between the vessels and the light. It does nothing for pigmented circles. In the wrong candidate it causes prolonged swelling and a bluish tint called the Tyndall effect.
What causes dark circles under the eyes in children?
Most often allergic shiners, which is venous congestion from allergic rhinitis, usually alongside a stuffy nose and mouth breathing. Inherited pigmentation is the other common cause. Both are benign. See a pediatrician if they appear suddenly, are one-sided, or come with fatigue or bruising elsewhere.
Are dark circles the same as under-eye bags?
No. A bag is a bulge, usually herniated fat. A dark circle is discoloration or shadow. They frequently occur together, since a bag casts a shadow that reads as a dark circle, but they are separate problems with separate treatments.
