We have all experienced pesky dark circles under our eyes at some point in our lives. Whether due to sleepless nights, stress, or genetics, these under-eye shadows can be quite bothersome.
But did you know there are different types of dark circles? Have you ever wondered what causes these dark circles?
In this blog, I will deep dive into the scientific explanations behind various types of dark circles, shedding light on the factors at play. So grab your reading glasses and let's explore the world of shadows!
Understanding Dark Circles: Anatomy of the Under Eye
To understand the types and causes of dark circles, we first need to examine the anatomy of the undereye area. The skin in this region is thinner and more delicate compared to the rest of our faces. The layer of skin under our eyes also contains more pigment cells and fewer oil glands, making it more susceptible to dryness and photodamage (just think more fine lines, wrinkles, and hyperpigmentation).
1. Vascular Dark Circles
One of the leading causes of under-eye dark circles is the presence of dilated blood vessels beneath the thin eye skin. When these blood vessels expand, they become more visible through the translucent skin, giving the appearance of dark circles. These types of dark circles are called vascular dark circles.
Genetics, ageing, and lifestyle choices can all have an impact on the dilation of these blood vessels, which causes them to peek through the skin and cause vascular dark circles.
2. Dark Circles From Melanin Pigmentation
Another type of under-eye dark circles is those caused by the presence of excess melanin, the pigment responsible for the colour of our skin, hair, and eyes. Increased melanin production or accumulation under the eyes can lead to hyperpigmentation, resulting in darker areas. Genetics, sun exposure, and certain medical conditions can influence melanin production.
3. Dark Circles From Fluid Bags & Swelling
Ever wake up with puffy eyes? Fluid retention and swelling can contribute to the appearance of dark circles under the eyes. When excess fluid accumulates around the eyes, it causes the skin to stretch and appear darker. Factors such as allergies, sinus congestion, a lack of sleep, and dietary habits can all contribute to fluid retention and cause these types of dark circles.
4. Dark Circles From Loss of Collagen & Skin Elasticity
Collagen and elastin are essential proteins responsible for maintaining the strength and elasticity of our skin. As we age, the production of these proteins decreases, leading to thinner and more fragile under eye skin. The loss of collagen and elastin can make blood vessels and pigmentation more visible, resulting in the appearance of dark circles.
Dark Circles Due To Lifestyle Factors
- Sleep deprivation: Lack of quality sleep can cause blood vessels to dilate, leading to under-eye shadows.
- Stress: Chronic stress can disrupt normal blood circulation and exacerbate under-eye dark circles.
- Poor nutrition: A diet lacking in essential nutrients can contribute to skin discolouration and fatigue.
- Smoking and alcohol: These habits can compromise blood flow and contribute to under-eye darkness.
Conclusion
Several factors come together to cause different types of dark circles, including vascular dark circles and those brought on by lifestyle choices. These include genetics, blood vessel dilation, pigmentation, fluid retention, collagen loss, and lifestyle choices. Understanding the underlying mechanisms can help us figure out how to get rid of dark circles by taking the appropriate measures.
Practising good sleep hygiene, managing stress, maintaining a healthy diet, protecting the skin from sun damage, and using specialised skincare products like eye serums for dark circles can all contribute to a brighter, more refreshed undereye area.
