Brown Dark Circles Under Eyes: What Causes Them?

Have you ever looked in the mirror and wondered, "Why are my dark circles brown?"

Brown dark circles under the eyes are one of the most common forms of dark circles, yet many people don't realise they are different from blue, purple or hollow-looking dark circles.

Understanding what causes brown dark circles under the eyes is the first step towards choosing the right skincare routine and setting realistic expectations.

In this guide, we'll explain the most common causes of brown dark circles, how to identify them, and what you can do to help improve their appearance.

What Are Brown Dark Circles Under Eyes?

Brown dark circles under the eyes are usually caused by excess pigmentation in the skin.

Unlike vascular dark circles, which often appear blue or purple due to visible blood vessels, brown dark circles are typically caused by increased melanin production around the eye area.

Melanin is the natural pigment responsible for the colour of our skin, hair and eyes. When excess melanin accumulates around the eyes, it can create the appearance of darker under-eye skin.

This type of dark circle is often referred to as pigmented dark circles or under-eye hyperpigmentation.

What Causes Brown Dark Circles Under Eyes?

There are several reasons why brown dark circles can develop.

1. Sun Exposure

One of the most common causes of brown dark circles under the eyes is sun exposure.

Ultraviolet (UV) rays stimulate melanin production, which can lead to pigmentation around the eyes.

Because the skin around the eyes is thinner and more delicate, pigmentation can often appear more noticeable in this area.

Daily SPF can help protect the skin from further sun-induced pigmentation.

2. Genetics

For some people, brown dark circles are hereditary.

If your parents or close family members have pigmented dark circles, you may be more likely to develop them yourself.

Genetic pigmentation often appears from a younger age and may be more difficult to improve than pigmentation caused by external factors.

3. Allergies and Eye Rubbing

Allergies can contribute to brown dark circles in two ways.

Firstly, inflammation can trigger increased pigmentation around the eyes. Secondly, frequent rubbing or scratching of the delicate eye area can lead to post-inflammatory hyperpigmentation.

Over time, repeated irritation may cause the skin beneath the eyes to appear darker.

4. Hormonal Changes

Hormonal fluctuations can sometimes increase melanin production, leading to pigmentation in various areas of the face, including around the eyes.

This is why some people notice changes in pigmentation during pregnancy, menopause or periods of hormonal imbalance.

5. Post-Inflammatory Hyperpigmentation

Any irritation or inflammation around the eyes can sometimes leave behind pigmentation.

Common triggers include:

• Eczema
• Dermatitis
• Allergic reactions
• Harsh skincare products
• Excessive rubbing

This type of pigmentation is known as post-inflammatory hyperpigmentation and can contribute to brown dark circles under the eyes.

Brown Dark Circles vs Blue Dark Circles

Many people confuse pigmented dark circles with vascular dark circles.

Brown Dark Circles

• Brown or grey-brown appearance
• Caused by excess melanin
• Often linked to sun exposure, hormones or genetics

Blue or Purple Dark Circles

• Blue, purple or pink appearance
• Caused by visible blood vessels
• Often linked to circulation, fatigue or thin skin

Understanding the difference is important because the underlying cause determines which approach may be most suitable.

How To Tell If Your Dark Circles Are Pigmented

You may have pigmented dark circles if:

• The area appears brown rather than blue or purple
• The darkness remains visible in all lighting conditions
• The colour does not significantly change throughout the day
• Family members also have similar pigmentation

If you're unsure, taking photographs in natural daylight can often help you assess the colour more accurately.

Can Brown Dark Circles Be Improved?

The appearance of pigmented dark circles may improve with a consistent skincare routine and by addressing factors that contribute to pigmentation.

Results can vary depending on the cause, severity and individual skin type.

The key is consistency and realistic expectations.

Pigmentation often develops gradually and may take time to improve.

How To Prevent Brown Dark Circles From Getting Worse

Wear SPF Daily

Protecting the skin from UV exposure is one of the most important steps in preventing pigmentation from becoming darker.

Avoid Excessive Eye Rubbing

Repeated friction can contribute to inflammation and pigmentation around the eyes.

Manage Allergies

Addressing allergy triggers may help reduce irritation and inflammation around the eye area.

Support Skin Hydration

Well-hydrated skin often appears healthier and brighter overall.

Ingredients Commonly Used For Pigmented Dark Circles

Ingredients commonly used in skincare for pigmented dark circles include:

• Vitamin E
• Rice Bran Oil
• Kiwi Seed Oil
• Apricot Kernel Oil
• Peach Kernel Oil

Final Thoughts

Brown dark circles under the eyes are often caused by pigmentation rather than tiredness alone.

Sun exposure, genetics, allergies, hormonal changes and inflammation can all contribute to the development of pigmented dark circles.

If you're experiencing brown dark circles, focus on protecting the skin, reducing irritation and maintaining a consistent skincare routine that supports the delicate under-eye area.
