If you have been dealing with dark circles for as long as you can remember — perhaps since your teens or early twenties — genetics is likely the dominant factor in your situation. If you have noticed them developing or worsening over the past few years alongside other changes to the skin beneath your eyes, ageing and cumulative environmental exposure are probably playing a significant role. And if the darkness is more pronounced on some days than others, lifestyle factors are amplifying whatever underlying structural or pigmentary cause exists.
Most people with dark circles have all three of these drivers operating to some degree — understanding how each contributes, and which is dominant in your individual situation, is what makes the difference between an approach that actually helps and one that does not.
Genetics: The Foundation
The genetic component of dark circles operates through several mechanisms. First, the structural anatomy of the under-eye area is inherited — the depth of the tear trough groove, the size and position of the orbital fat pads, and the prominence of the bony orbital rim all have a genetic basis. People who inherit a deep tear trough will tend to have more structural shadowing beneath the eyes regardless of lifestyle.
Second, the tendency toward periorbital pigmentation has a genetic basis. In South Asian, Southeast Asian, and East Asian populations, the melanocytes of the periorbital skin are often inherently more active and more prone to overproduction of melanin — a pattern that runs in families and presents from relatively early in life.
Third, the thickness and translucency of periorbital skin is partly inherited. People with naturally thin periorbital skin will show the underlying vasculature more easily, contributing to bluish or purplish tints beneath the eye.
The genetic component of dark circles is not something that lifestyle changes or topical products can address at the root level.
UV Exposure: The Accelerant
In Singapore’s equatorial climate, UV exposure is a year-round, daily reality. The UV index regularly reaches extreme levels even on overcast days, and most people leave the periorbital area completely unprotected. UV light stimulates melanin production as a protective response — in the already-reactive periorbital melanocytes of people with Asian skin, this means accelerated pigmentation development over time. UV also degrades the collagen and elastin of the periorbital skin, accelerating the thinning and loosening that makes structural shadows more visible and allows blood vessels beneath the skin to show through.
Consistent daily SPF of the periorbital area is one of the most impactful preventive measures available and is underused by the overwhelming majority of people in Singapore.
Lifestyle: The Amplifier
Lifestyle factors do not typically cause dark circles at the root level — but they amplify their severity significantly. Poor sleep elevates cortisol, dilates blood vessels, and impairs the skin’s repair processes. High sodium intake causes fluid retention that creates periorbital puffiness and shadow. Alcohol worsens under-eye darkness and puffiness. Unmanaged allergies cause chronic low-grade periorbital inflammation and eye-rubbing that compounds the appearance of dark circles.
Managing these lifestyle factors consistently reduces the day-to-day severity of dark circle appearance. But for people whose dark circles are primarily genetic and structural, lifestyle changes alone will not produce the fundamental improvement that addresses the root cause.
What Treatment Can Achieve
For patients whose dark circles are primarily driven by structural shadowing — tear trough hollowing creating a persistent shadow regardless of sleep or lifestyle — eye filler placed along the tear trough is often the single most effective treatment available. By restoring the volume that has been lost and smoothing the under-eye contour, eye filler eliminates the hollow that is casting the shadow. The improvement is structural rather than cosmetic — it addresses the cause of the darkness rather than attempting to conceal it.
For patients whose dark circles are primarily pigmentary, laser treatments and topical brightening agents targeting melanin production are the relevant path. For those with a combination of causes — which is most common — a treatment plan that addresses each component appropriately produces the most comprehensive result.
