Dark circles around the eyes are something that almost everyone has noticed at some point. They can make you appear fatigued, anxious, or older than you really are. What makes them frustrating is that many people are unsure why they appear in the first place.
“Dark circles are rarely caused by just one reason,” explains Dr Sunil Kumar Prabhu, Consultant Dermatologist and Aesthetic Physician at Aster RV Hospital in Bangalore. “In most people, it is a mix of lifestyle habits, skin type, and sometimes genetics.”
The skin around our eyes is significantly thinner than the rest of our face. As a result, even minor changes in blood flow, hydration, or pigmentation become apparent fast in this area.
Lack of sleep is the most common reason.
Inadequate sleep is one of the leading causes of dark circles. When you don’t get enough sleep, the blood vessels under your eyes expand and become more visible, resulting in a dark, shadowy appearance.
“When the body does not get enough rest, it shows up first around the eyes,” says Dr Prabhu. “Adequate sleep allows the skin to repair itself naturally.”
Despite getting plenty of sleep, some people nevertheless get dark circles. This is frequently attributed to genetics. If dark circles occur in your family, the skin around your eyes could be thinner or more pigmented.
Screen Time and Eye Strain
Long periods of time spent on phones, laptops, or watching television also contribute to this. Continuous eye strain makes the muscles around the eyes work harder, resulting in expanded blood vessels that make the area appear darker.
“Our modern screen-heavy lifestyle has made under-eye darkness more common, even among young adults,” Dr Prabhu points out.
Allergies, Dehydration, and ageing
Allergies are another common trigger. Constant scratching and rubbing can injure the sensitive under-eye skin, resulting in discolouration. Asthma can induce nasal congestion, which darkens the colour around the eyes.
Dehydration is commonly neglected, yet it has a noticeable impact. When the body lacks water, the skin becomes dull and sunken, making dark circles more visible.
Collagen levels decrease with ageing, and the skin thins. This makes the veins beneath the eyes more prominent. Sun exposure can exacerbate the problem by increasing melanin levels, particularly in individuals with medium to dark skin tones.
Simple Ways to Reduce Dark Circles.
Understanding the underlying causes of dark circles is the first step towards treatment. Good sleep is essential—ideally, seven to nine hours every night. Staying hydrated throughout the day makes the skin appear fuller and healthier.
“Small daily habits can make a big difference over time,” Dr Prabhu explains.
Cold compresses such as ice packs, chilled spoons, or cucumber slices can temporarily reduce puffiness and darkening by constricting blood vessels. Moisturising on a regular basis is similarly crucial. Eye treatments containing vitamin C, hyaluronic acid, peptides, or niacinamide can strengthen the skin and improve discolouration over time.
Another important step is to protect the under-eye area from sunlight. Using sunscreen and sunglasses outside helps prevent further discolouration and squinting.
Taking regular breaks from screens helps the eye muscles relax. If allergies are a problem, treating them with prescribed medication and avoiding excessive eye rubbing can be quite beneficial.
When to Visit a Dermatologist
If your dark circles are mostly caused by heredity or deep pigmentation, home care may not be sufficient. In such circumstances, skilled dermatological treatments can produce superior outcomes.
“Dark circles are not a medical problem, but they do affect confidence,” Dr Prabhu explains. “With consistent care, most people will see improvement over time.”
Finally, a mix of good sleep, hydration, sun protection, and moderate skincare can help keep the under-eye area healthy and bright.
