They may appear after nights of endless laughter, early mornings chasing dreams, or even moments of stress. This delicate area of the face, where the skin is thinnest, easily reflects changes in our body—whether from lack of sleep, genetics, or the passage of time.
While we often associate dark under-eye circles with tiredness, they actually have multiple causes and types. And no matter where they come from, there might be times when you’d like to soften their appearance and bring brightness back to your eyes.
Today, we’re diving into everything you need to know about dark circles—what they really are, why they appear, and, of course, how to help reduce them.
What are dark circles under eyes?
When you hear the term “dark circles,” you probably picture shadows or discoloration around the eyes. But they’re more than just a change in color—they’re little windows into our physical, emotional, and even genetic state. The skin around the eyes is the thinnest and most delicate on the face, almost like a veil that reveals what’s happening underneath—circulation, pigment buildup, or even signs of aging.
Though dark circles are often linked to tiredness or stress, that’s not always the case. Understanding their causes can help us manage them better—and even view them more kindly. At the end of the day, they’re part of your skin’s story and what makes you unique.
What’s the reason for dark circles?
Dark circles aren’t the same for everyone, but they often stem from a few specific factors:
- Genetics: If your parents or grandparents have dark circles, you might have them too. It’s not a flaw—just a part of your genetic makeup, like your eye color or smile shape. Genetics affect pigmentation and skin’s thickness around the eyes, making dark circles more noticeable for some.
- Lack of sleep: Burning the midnight oil can leave its mark. Sleep is crucial for skin regeneration, and without enough rest, blood vessels in the eye area can become more visible.
- Aging: Over time, our skin changes, and the eye area is no exception. The natural decline of important building blocks such as collagen and elastin can make shadows under the eyes more prominent.
- Allergies: Reactions to external factors like pollen or congestion can cause temporary darkening around the eyes.
- Lifestyle factors: Every decision leaves an imprint. A balanced diet, movement, and self-care help to keep skin vibrant. But if that late night was worth it, just think of your dark circles as proof that you’re living life to the fullest.
Types of dark circles
1. Pigmented dark circles
These have a brown or yellowish tint, almost as if your skin held onto a little extra sunshine. More common in deeper skin tones or those with a genetic predisposition, these circles result from melanin buildup (the natural color your skin produces to protect itself). If this sounds like you, remember: it’s completely natural and very common!
2. Vascular dark circles
Bluish, purplish, or even reddish, these dark circles reflect the activity beneath the skin. They often arise from dilated blood vessels or fluid retention, something totally normal in such a delicate area. If your dark circles vary in intensity depending on the day, they might be vascular.
3. Hollow dark circles
These aren’t so much about color but rather the play of light and shadow. They appear when volume is lost in the under-eye area, creating a slight indentation. They often develop over time, as a natural part of your skin’s journey.
How to reduce the look of dark circles
The secret is in your skincare routine (and a few simple changes that can work wonders). And when it comes to eye care, nothing beats step two: an eye contour solution.
