Learn why dark circles can appear under the eyes, the different factors that can contribute to them, what skincare can realistically do, and how to build a simple routine for the delicate eye area.
Dark circles are a darker or shadowed appearance around the under-eye area. They can look brown, blue, purple, grey or deeper than the surrounding skin depending on the underlying cause and individual skin characteristics.
Dark circles are not caused by one single factor. Genetics, pigmentation, visible blood vessels, allergies, skin thickness, ageing and the natural structure of the area around the eyes can all contribute to their appearance.
Some under-eye darkness comes from pigment, while other cases can be related to visible vessels, thin skin or shadows created by hollows and facial structure. Identifying the likely cause matters when choosing skincare.
Several factors can contribute to under-eye darkness. More than one factor can also be present at the same time.
Some people naturally have more visible under-eye darkness because of inherited skin characteristics, pigmentation or facial structure.
Increased pigmentation around the eyes can contribute to brown or darker-looking under-eye skin.
The skin around the eyes is delicate. When underlying structures or blood vessels are more visible, the area can appear darker.
Nasal congestion associated with allergies can contribute to dark-looking circles known as allergic shiners.
Changes in skin thickness, elasticity, fat distribution and facial contours can make under-eye shadows more noticeable.
Poor sleep or fatigue can make the area around the eyes look more tired or shadowed, although sleep is not the only cause of persistent dark circles.
Looking at the colour and appearance of the under-eye area can provide clues about what is contributing to the darkness, although appearance alone cannot establish a medical diagnosis.
Brownish darkness may be associated with increased pigmentation. Sun exposure and repeated irritation can also influence pigmentation.
Blue, purple or reddish tones may become more noticeable when the skin is thin and underlying blood vessels are visible.
Tear-trough hollows and changes in facial contours can create shadows that make the under-eye area appear darker.
Many people have more than one contributing factor, such as pigmentation together with natural shadowing.
Dark circles and under-eye bags are often mentioned together, but they are not the same concern.
The main concern is a darker or shadowed appearance beneath the eyes. Pigmentation, visible vessels and facial structure can all contribute.
Bags generally refer to puffiness or protrusion beneath the eyes. Fluid retention, tissue changes and age-related structural changes can contribute.
Puffiness can create additional shadows, making an existing dark appearance seem more noticeable.
Topical skincare may support skin quality and pigmentation, but structural hollows or pronounced bags may not be fully corrected with skincare alone.
The most appropriate ingredient depends on what is contributing to the under-eye appearance. Products designed specifically for the eye area are generally preferable because the skin around the eyes is delicate.
Vitamin C is commonly used in skincare focused on uneven pigmentation and antioxidant support. Use products formulated appropriately for the eye area.
Niacinamide is used in many routines targeting uneven tone and supporting the skin barrier. Tolerance around the eyes varies by formulation.
Caffeine is commonly included in eye products aimed at temporarily improving the appearance of puffiness and tired-looking eyes.
Retinoids can be used in some anti-ageing routines, but the eye area can be sensitive. Follow product directions and avoid getting products into the eyes.
Hyaluronic acid is primarily used as a hydrating ingredient and can help support a moisturised, comfortable skin surface.
Sun protection is important when pigmentation is a concern. Use a sunscreen suitable for the face and apply carefully around the eye area according to its directions.
Avoid applying strong acids, retinoids or other irritating products too close to the eyes unless the product is specifically intended for that area.
A simple routine is usually easier to maintain than layering multiple strong products around the delicate eye area.
Cleanse the face without aggressively rubbing or pulling the skin around the eyes.
If you use an eye serum or cream, choose a formulation intended for the eye area and follow its instructions.
A suitable moisturiser can help maintain comfortable, hydrated skin around the eyes.
Include broad-spectrum sunscreen in your daytime routine and use appropriate sun protection around the face.
Skincare is only one part of under-eye care. Some temporary changes in appearance can also be influenced by sleep, allergies, fluid retention and other everyday factors.
Improving sleep quality may help reduce a tired-looking appearance, although persistent dark circles can have other causes.
If nasal allergies are contributing to dark-looking circles, addressing the underlying allergy may be more useful than simply applying cosmetic products.
Repeated rubbing can irritate the delicate skin around the eyes and may worsen irritation or discoloration.
Remove makeup gently and avoid aggressive scrubbing around the eyes.
The eye area is delicate, so aggressive treatments can sometimes create more irritation rather than improving the appearance.
Pigmentation, visible vessels, allergies and structural shadowing can have different contributing factors. A routine should be based on the likely cause rather than simply adding more active ingredients.
Ordinary dark circles are often a cosmetic concern, but a sudden or unusual change around the eyes should not automatically be treated as a skincare problem.
If the appearance is sudden, unusual, painful or associated with vision changes, seek appropriate medical or eye-care advice rather than relying only on cosmetic products.

Dark circles can have several contributing factors, including genetics, pigmentation, visible blood vessels, allergies, ageing, skin characteristics and shadows caused by facial structure.
Poor sleep or fatigue can make the under-eye area look more tired or shadowed. However, persistent dark circles can have other causes that are unrelated to sleep.
It depends on the underlying cause. Skincare may help improve some aspects of pigmentation or skin quality, while genetic, structural or age-related factors may not be completely corrected with topical skincare.
Ingredients such as vitamin C, niacinamide, caffeine, retinoids and hydrating ingredients may be used in different under-eye routines. The appropriate choice depends on the likely cause and the sensitivity of the eye area.
Vitamin C is commonly used in skincare targeting uneven pigmentation and antioxidant support. It may be useful when pigmentation contributes to the appearance, but it will not correct every type of dark circle.
Caffeine is commonly included in eye products designed to improve the appearance of puffiness and tired-looking eyes. Its usefulness depends on what is causing the under-eye appearance.
Retinoids may be used in some routines for skin ageing and pigmentation, but the eye area can be sensitive. Only use a product as directed and avoid getting it into the eyes.
No. Dark circles mainly refer to darker or shadowed coloration, while eye bags generally refer to puffiness or protrusion beneath the eyes. They can occur together.
Yes. Nasal congestion associated with allergies can contribute to dark-looking circles known as allergic shiners.
The skin around the eyes is delicate. Strong exfoliating acids should not be applied close to the eyes unless the specific product is designed and labelled for that area.
Sun protection is particularly relevant when pigmentation is contributing to uneven skin tone. Use a suitable broad-spectrum sunscreen as part of your daytime routine.
Seek professional advice if under-eye changes are sudden, painful, significantly swollen, associated with vision changes, or accompanied by other unusual symptoms.
