Dark Circles Under the Eyes: Common Causes and What...

Dark circles under the eyes can make you look tired even when you feel fine. They are one of the most common cosmetic concerns, and our earlier article Are Dark Eyelids a Health Warning? remains one of the most-read posts on our blog. This updated guide explains the many causes of under-eye darkness, which ones you can change, and when to talk to a doctor.

Why the Under-Eye Area Is Special

The skin under your eyes is among the thinnest on your body, roughly 0.5 mm compared with around 2 mm on the cheeks. It has little fat beneath it and sits over a network of small blood vessels and the muscle that circles the eye. That makes it more transparent and more likely to show colour changes, shadows and puffiness.

The Main Causes of Dark Circles

1. Genetics

Dark circles often run in families. Some people inherit thinner skin, more visible blood vessels, deeper eye sockets or more pigment in the area.

2. Pigmentation (periorbital hyperpigmentation)

Extra melanin can make the under-eye area brown. This is more common in people with medium to darker skin tones, including many people of South Asian, Middle Eastern and African heritage. Sun exposure and rubbing can worsen it.

3. Visible blood vessels

When the skin is thin, the blood pooling in small veins can show through as blue or purple. Tiredness, dehydration and congestion can make this more noticeable.

4. Shadows from structure and ageing

With age, the skin loses collagen and the fat pads around the eyes shift, creating a hollow called the tear trough. Light then casts a shadow that looks like darkness. Read about collagen in our collagen and skin aging guide.

5. Lack of sleep

Poor sleep can make skin paler and dull, making circles more visible. See our sleep hygiene habits.

6. Allergies and nasal congestion

"Allergic shiners" are dark circles caused by congestion in the small veins around the nose and eyes. Rubbing itchy eyes worsens pigmentation. Read our seasonal allergies guide.

7. Eye strain and rubbing

Long screen hours and rubbing tired eyes can irritate the delicate skin; see eye health and screen time.

8. Iron deficiency

Iron deficiency anaemia can cause pale skin that makes under-eye circles more prominent. Some studies have found low iron more common in people with dark circles. If you also have fatigue, breathlessness or pale nails, ask your doctor for a blood test.

9. Lifestyle factors

Smoking, heavy alcohol, high-salt meals (causing puffiness) and dehydration can all make the area look worse.

What Actually Helps

Lifestyle

Prioritise sleep and sleep with your head slightly raised if you wake with puffiness.
Treat allergies and avoid rubbing your eyes.
Stay hydrated and limit salty, processed foods; see our hydration guide.
Do not smoke and limit alcohol.
Protect from sun: wear sunglasses and apply sunscreen around the eyes, as UV worsens pigmentation; read our sun safety guide.

Simple home care

Cold compress: a cool, damp cloth or chilled spoons for a few minutes can reduce puffiness and the appearance of blood vessels.
Cooled tea bags: some people use cooled, steeped tea bags as a compress. The cold does most of the work; caffeine in green or black tea may help slightly with puffiness.
Gentle moisturising: a fragrance-free eye cream or light moisturiser keeps the area supple. Pat, do not rub.

Skincare ingredients with some evidence

Vitamin C: may help brighten pigmentation and support collagen.
Retinol: may thicken skin slightly over time; use gentle formulations made for the eye area.
Niacinamide, azelaic acid and kojic acid: used for pigmentation.
Caffeine: may temporarily reduce puffiness.

Hydrating products such as the Korean Collagen Ampoule can improve the look of dry, crepey skin when patted gently around (not into) the eye area. Patch test first and avoid getting products in the eyes.

Professional options

Dermatologists may offer prescription creams, chemical peels, laser treatments or tear-trough fillers depending on the cause. Choose qualified professionals.

When Dark Circles May Signal a Health Issue

Dark circles are usually harmless, but see a doctor if they:

Appear suddenly or affect only one eye
Come with swelling, pain or vision changes
Accompany fatigue, breathlessness or pale skin (possible anaemia)
Come with puffiness of the legs or ankles (possible kidney, heart or thyroid issues)

Eat for Your Skin

A diet rich in iron (beans, leafy greens, meat), vitamin C (citrus, peppers, berries) and antioxidants supports healthy skin and blood. Our anti-inflammatory eating guide shows how.

Frequently Asked Questions

Do cucumber slices work for dark circles?

The coolness can temporarily reduce puffiness, much like any cold compress. They do not change pigmentation.

Will more sleep get rid of my dark circles?

If tiredness is a factor, it helps. But if your circles are genetic or due to pigmentation or structure, sleep alone may not change them much.

The Takeaway

Dark circles have many causes, and genetics often play a big role. Focus on what you can change: sleep, allergies, sun protection, not rubbing your eyes, and a nutrient-rich diet. And if they come with other symptoms, check in with your doctor.
