what causes dark circles
Dark circles are usually caused by a mix of genetics, lifestyle, and skin changes around the eyes, rather than just “being tired.”
Quick Scoop: Main Causes
- Genetics and natural skin tone
- Some people are born with more pigment under the eyes or naturally thinner skin there, making blood vessels show through more.
* Dark circles are more common and more noticeable in people with darker skin tones due to a tendency toward hyperpigmentation.
- Lack of sleep and fatigue
- Poor or too little sleep can make the skin look paler and dull, so the vessels and shadows under the eyes stand out more.
* Being overtired can also cause mild puffiness; the resulting shadows can look like darker circles.
- Hyperpigmentation (extra pigment)
- Overproduction of melanin under the eyes leads to brownish or gray circles.
* This can be triggered or worsened by sun exposure, previous irritation, or rubbing the area (post‑inflammatory pigmentation).
- Aging and skin thinning
- As you age, you lose some of the fat and collagen that keep skin thick and smooth, especially around the eyes.
* Thinner skin makes underlying blood vessels and natural hollows more visible, which reads as dark circles.
- Facial structure and shadows
- Deep tear troughs (hollows under the lower eyelid) create shadows that look like dark circles even if the skin color itself isn’t very different.
* Sudden or major weight loss can deepen these hollows, increasing shadowing.
- Allergies and skin conditions
- Allergies, eczema, or contact dermatitis around the eyes can cause chronic rubbing, swelling, and increased blood flow, which darkens the area over time.
* Long‑term irritation can also trigger hyperpigmentation in the eye area.
- Lifestyle factors (everyday habits)
- Smoking, high alcohol intake, high stress, and poor diet can impair circulation and skin health, making circles more prominent.
* Dehydration can make the under‑eye area look sunken and dull, accentuating darkness.
- Medical and nutritional issues
- Conditions like anemia, malnutrition, asthma, allergies, and some kidney or liver diseases can be associated with darker under‑eye skin in some people.
* Certain medications (including some glaucoma drops and drugs that cause pigment changes) may also darken the under‑eye area.
Simple way to think about it
Most dark circles come from one or more of these buckets working together:
- extra pigment in the skin,
- visible blood vessels or pooled blood under thin skin,
- actual shadows from hollows or puffiness, and
- overall health and lifestyle factors that affect skin and circulation.
| Cause type | What it looks like | Typical triggers |
|---|---|---|
| Genetic / natural | Dark since youth, often runs in family | [5][7]Inherited pigment pattern, natural facial structure | [7][5]
| Sleep & fatigue | Dull, tired look, sometimes puffy in mornings | [9][1]Short sleep, irregular sleep schedule, chronic tiredness | [1][9]
| Hyperpigmentation | Brown or gray tone under the eyes | [3][1][7]Sun, rubbing, eczema, darker skin type | [1][3][7]
| Aging / thinning skin | Visible vessels, hollow or “sunken” look | [3][5][1]Natural aging, collagen loss, weight loss | [5][1][3]
| Allergies / irritation | Darkness with itch, swelling, or redness | [1][3][5]Hay fever, eczema, eye rubbing, contact reactions | [3][5][1]
| Lifestyle | General dullness, enhanced lines and shadows | [9][5][1]Smoking, alcohol, stress, poor diet, dehydration | [9][5][1]
| Medical / meds | Persistent or gradually worsening darkness | [7][5][1]Anemia, organ disease, some medications | [5][7][1]
