What Causes Dark Circles? Causes, Types and Treatments

What Causes Dark Circles? Causes, Types and Treatments
Published: Jul 09, 2026

Let me start with a confession. I have had dark circles since I was 16. And I am not talking about those cute little shadows you get after a bad night. I am talking about the kind that makes people ask "are you okay?" every single day. The kind that concealer cannot fully hide no matter how much you layer.

I tried everything. Those expensive eye creams. Cucumber slices. Tea bags. Cold spoons. Gold under eye patches. Nothing gave permanent results. Some stuff worked temporarily. Most did nothing.

Then I finally stopped blaming sleep and started understanding what causes dark circles. And let me tell you, it is not just about staying up late.

What Actually Causes Dark Circles?

Here is the thing nobody tells you. Dark circles are not one single problem. They have different causes. And until you figure out which one is yours, you will keep wasting money on products that do not work. So let me break down the real reasons.

The Skin Under Your Eyes is Thin

This is the most basic reason. The skin under your eyes is the thinnest skin on your entire body. And I mean really thin. Like 0.5 millimeters thin. Compare that to other parts of your face and you will understand why.

Because it is so thin, you can see what is underneath. Blood vessels. The dark blue purple color of veins. When blood pools under your eyes, it shows right through. And it looks like dark circles.

This is also why older people have more dark circles. As you age, your skin gets even thinner. The fat under your eyes decreases. The darkness becomes more visible.

Blood Vessels Under Your Eyes Get Stretched

The blood vessels under your eyes are tiny and delicate. When they get stretched or leak, blood collects under the skin. This blood looks blue or purple. And because the skin is so thin, you see it clearly.

What causes these vessels to stretch? Rubbing your eyes. Sleeping on your face. Fluid retention from salty food. All of these make the vessels expand. Then you get dark circles.

Genetics - Thanks Mom and Dad

Some people are just born with dark circles. Their skin is naturally thinner. Or their blood vessels are naturally closer to the surface. Or their eye shape creates shadows.

If your parents have dark circles, chances are you will have them too. And no cream is going to change your genetics completely. You can improve them but you cannot erase them. This was hard for me to accept honestly.

Allergies and Sinus Problems

This one is so common in India. We have dust and pollution everywhere. Our sinuses get blocked. We rub our eyes constantly. And this causes dark circles.

When you have allergies, your body releases histamine. Histamine makes your blood vessels dilate. More blood flows under your eyes. You get that dark appearance.

Also when you have sinus congestion, blood pools around your eyes. Your nose and the area between your nose and eyes especially. This is why some people have dark circles specifically in the inner corner near the nose.

Sun Damage Makes It Worse

The skin under your eyes is sensitive. You probably do not put sunscreen there. But you should. Sun exposure increases melanin production. This means pigmentation. And pigmentation under your eyes looks like dark circles.

People who spend a lot of time in the sun without protection get darker under eyes over time. This is particularly visible in Indian skin because we are prone to hyperpigmentation.

Types of Dark Circles

A visual comparison chart showing the four main types of dark circles: vascular, pigmented, structural, and lifestyle-related.

Not all dark circles are the same. Here are the four main types.

Vascular Dark Circles

These are blue or purple. They are caused by blood vessels under the skin. When you stretch the skin under your eye, the color changes. If it turns darker or lighter, you have vascular dark circles.

These are mostly genetic. But allergies and lack of sleep make them worse. Eye creams with vitamin K or caffeine help with these. They constrict blood vessels.

Pigmented Dark Circles

These are brown or grey. They look like patches of pigmentation. When you stretch the skin, the color does not change. Because the color is in the skin itself, not in the blood vessels.

These are caused by sun exposure. Also by rubbing your eyes. And sometimes by eczema or dermatitis. People with darker skin tones get these more often.

Vitamin C and retinol help with these. They fade pigmentation slowly over time. Hydroquinone is stronger but prescription only.

Structural Dark Circles

These are not actually dark circles. They are shadows. When your eyes are deep set or you have hollows under your eyes, light does not hit those areas properly. It creates a shadow that looks like darkness.

Age makes this worse. The fat under your eyes decreases. The bones become more prominent. The hollows deepen.

No cream will fix structural dark circles. You need fillers or fat transfer for these. Only medical procedures work.

Lifestyle Dark Circles

These are temporary. They come from lack of sleep. Or too much screen time. Or dehydration. Or poor diet.

The good news is these can be fixed. Improve your sleep. Drink more water. Reduce salt. Cut screen time. Within a few weeks, these circles improve.

What Causes Dark Circles Around the Eyes in Adults?

As an adult, new things start contributing to dark circles that did not matter when you were young.

Weight Changes

When you lose weight rapidly, you lose fat from your face. The fat under your eyes disappears. The skin becomes hollow. The hollow creates shadows. Shadows look like dark circles.

This is why crash dieting makes your face look older. Your eyes look sunken. The darkness becomes more noticeable.

Hormonal Changes

Pregnancy. Menopause. Thyroid issues. These affect your hormones and your skin. The skin becomes thinner. Pigmentation increases. Your dark circles get worse.

Many women notice dark circles during pregnancy. It is normal. Usually goes away after delivery. But sometimes it stays.

Medication Side Effects

Some medicines dilate your blood vessels. This includes blood pressure medications. Including those used for heart conditions. Also certain allergy pills. And steroids.

When blood vessels dilate, they show through the thin under eye skin. You get dark circles even if you sleep perfectly.

Anemia and Iron Deficiency

This is very common in Indian women. Low iron means less oxygen reaches your skin. Your skin becomes pale. The blood vessels under your eyes become more visible. The dark circles look worse.

If you feel tired all the time and have dark circles, get your hemoglobin checked. Iron supplements might help.

What Causes Dark Circles Between Eyes and Nose?

This specific area is interesting. The inner corner of your eye, near your nose, is where many people have the darkest circles.

Sinus Pressure

Your sinuses are located right behind this area. When they are inflamed, blood vessels dilate. The skin in this area is especially thin. Darkness shows up clearly.

Nasal Congestion

When your nose is blocked, veins around your nose and eyes swell. Blood flow increases. The area looks darker.

Allergic Shiners

Doctors call them allergic shiners. Dark circles specifically at the inner corners near the nose. When you have allergies, your nasal passages swell. Blood flow slows. It pools in this area.

Eye Rubbing

This is where most people rub their eyes. Right near the nose. Rubbing causes tiny blood vessels to break. Blood leaks under the skin. And the inner corner area turns dark.

Foods That Cause Dark Circles Under Eyes

A healthy lifestyle comparison showing processed salty foods versus fresh water-rich foods for skin health.

You eat something today and your eyes look tired tomorrow. Here is why.

Salt and Sodium

  • Too much salt makes your body retain water. Water retention makes your under eye area puffy. The puffiness creates shadows. Shadows look like dark circles.
  • Also salt affects your blood circulation. When circulation is poor, blood pools under your eyes. The dark appearance increases.
  • Reduce your salt intake. Stop adding extra salt to food. Avoid processed snacks. Your eyes will look better.

Sugar

  • Sugar causes inflammation. Inflammation affects your blood vessels. They become leaky. Blood collects under your eyes.
  • Also sugar damages collagen. Collagen keeps your skin plump and thick. Damaged collagen means thinner skin. Thinner skin shows more darkness.

Caffeine and Alcohol

  • Both dehydrate your body. Dehydrated skin looks dull. The under eye area becomes hollow. Hollow areas create shadows.
  • Alcohol also dilates blood vessels. Dilated vessels show through the thin under eye skin. You get dark circles even after good sleep.

Foods That Cause Allergies

  • Everyone has different food triggers. Dairy can cause bloating and under eye puffiness. Gluten causes inflammation in some people. Soy and nuts are allergens for others.
  • If you notice dark circles after eating certain foods, you might have mild food allergies. Try eliminating foods one at a time. See if your eyes look better.

Processed Foods

  • Packaged foods have preservatives and additives. These cause fluid retention. They also increase inflammation. Both contribute to dark circles.
  • Eat fresh foods. Cook at home. Your skin will thank you.

Other Things That Make Dark Circles Worse

Screen Time

  • Blue light from screens penetrates deep into your skin. It breaks down collagen. It also causes pigmentation. Under eye skin gets affected more because it is already thin.
  • Take breaks from screens. Every 20 minutes, look away for 20 seconds. Blink often. This reduces eye strain and dark circles.

Not Removing Makeup

  • Sleeping with eye makeup on. The leftover mascara and kajal stay in your pores. They also cause pigmentation. Skin under eyes gets darker over time.
  • Always remove eye makeup properly. Use a gentle eye makeup remover. Then wash your face.

Rubbing Your Eyes

  • I know you do it. I do it too. But rubbing breaks blood vessels. The broken vessels leak blood. Leaked blood looks like darkness.
  • Instead of rubbing, apply something cold. Cold reduces inflammation. It also constricts blood vessels.

Stress

  • Stress increases cortisol. Cortisol affects your sleep. It also affects your blood circulation. Poor circulation means blood pools under your eyes.
  • Find ways to reduce stress. Walk in the morning. Listen to music. Talk to friends. Your eyes will reflect your calmness.

Smoking

  • Smoking damages collagen. Damaged collagen means thinner skin. Thinner skin means visible blood vessels. Visible vessels mean dark circles.
  • Also smoking reduces oxygen to your skin. Oxygen deprived skin looks dull and grey. Dark circles become more prominent.

What Actually Works for Dark Circles?

Okay enough about causes. Here is what I did that actually helped.

Sleep

Yes obviously. But here is the thing. Quality matters more than quantity. 6 hours of deep sleep is better than 8 hours of light sleep. Elevate your head while sleeping to reduce fluid retention under eyes.

Water

Drink 2 to 3 liters daily. Dehydrated skin looks thin and tired. Hydrated skin looks plump and bright. The difference is visible.

Cold Compress

Apply something cold under your eyes. Ice cubes wrapped in cloth. Cold spoons. Chilled cucumber slices. This constricts blood vessels. The dark appearance reduces immediately.

Eye Creams

Some ingredients actually work. Vitamin C for pigmentation. Retinol for thickening skin. Caffeine for reducing puffiness. Hyaluronic acid for hydration.

But do not expect miracles from a cream. They help but not fix genetics.

Sunscreen

Apply sunscreen under your eyes. The delicate skin needs protection. Choose a gentle SPF that does not sting your eyes.

Diet Change

Reduce salt and sugar. Eat antioxidant rich foods. Berries, citrus fruits, leafy greens. These reduce inflammation and help skin repair.

Sleep Position

Sleep on your back. Sleeping on your side or stomach causes fluid to pool under your eyes. In the morning you have puffiness. Puffiness creates shadows. Shadows look like dark circles.

Products I Actually Recommend

I have tried so many. These worked somewhat.

  • Vitamin C serum - Use around your eyes. Fades pigmentation slowly. Takes at least a month to see difference.
  • Retinol eye cream - Thickens skin over time. Thicker skin means less visible blood vessels. Start with low concentration. Use alternate nights.
  • Caffeine eye gel - Works temporarily. Good for morning puffiness. Gives instant but short term improvement.
  • Hyaluronic acid eye serum - Plumps up the under eye area. Less hollowness means less shadow. Use before moisturizer.
  • Under eye patches - Great for emergencies. Before an event or meeting. Gives instant brightening.

What Does Not Work?

I want to be honest. Some things are a waste of money.

  • Expensive creams with gold or platinum - Marketing gimmick. No real benefits.
  • Under eye rollers - Feel good but do nothing long term.
  • Home remedies with potato juice - Myth. Does not lighten skin.
  • Tea bags - Green tea bags have caffeine which constricts vessels. Works temporarily. But brown tea bags? Leave stains.
  • Toothpaste under eyes - Please no. Burns skin. Damages the delicate area.

When to See a Doctor?

  • If your dark circles come with other symptoms. Puffiness that does not go away. Pain or itching. Vision changes.
  • If you have allergies that you cannot manage. Sinus infections that keep returning. Thyroid symptoms. See a doctor.
  • If dark circles suddenly appear without reason. Or become much worse. Get a checkup. Sometimes it indicates anemia or kidney issues.

Managing Expectations

Here is the honest truth. Some dark circles never go away completely. Genetics play a big role. You can improve them but not erase them.

And that is okay. Everyone has something about their face they do not like. Dark circles do not make you ugly. They do not make you tired. They are just part of you.

I still have dark circles. They are lighter than before. People no longer ask if I am sick. But they are still there. And I have made peace with that.

Final Words

Dark circles are frustrating. I get it. I have lived with them for years. But obsessing over them makes it worse. Stress affects hormones. Hormones affect skin. Everything is connected.

Do what you can. Sleep better. Drink water. Eat less sugar. Use sunscreen. Apply a good eye cream. Manage allergies. Reduce screen time.

Beyond that, accept the rest. Your dark circles do not define your beauty. They are just a small part of a much bigger person. Now stop staring at yourself in the mirror. Go live your life.
