Dark Circles: Causes and What Helps

Why the under-eye area is different

A review of the causes of dark circles describes several that can occur together: extra pigment, thin skin that lets blood vessels show through, and shadowing from hollows under the eye (Vrcek et al., 2016). That is why they vary so much from person to person and why the right approach depends on the cause.

The four main causes

A quick home check

1. Look at the area in good daylight, not under a bathroom light.
2. Gently stretch the skin sideways. If the colour stays, it is likely pigment. If it fades or shifts, it is likely vascular.
3. Tilt your head back and then forward under a light. If the darkness moves or disappears, a shadow from the contour is a large part of it.

This is only a rough guide. A dermatologist can tell you which type you have and what to expect.

What often makes it worse

• Short or broken sleep. After a night of sleep loss, faces were seen as having darker under-eye circles, paler skin and redder, more swollen eyes (Sundelin et al., 2013). See sleep and your face.
• Allergies and rubbing. Rubbing irritates the delicate skin and may leave lasting pigment, so try not to rub.
• Sun exposure. Sun drives most visible facial ageing (Flament et al., 2013). In a small study of darker skin, visible light caused darker, longer-lasting pigmentation than long-wave UVA (Mahmoud et al., 2010). Use sunscreen and sunglasses.
• Alcohol and very salty food. Some people find these make them look puffier the next morning. That is common experience, not something we can point to trials for.
• Smoking. In identical twins, the twin who smoked longer looked older (Guyuron et al., 2009).
• Ageing and weight loss. Hollows under the eye cast shadows (Vrcek et al., 2016), and losing volume there may deepen them.

What actually helps

Protect from sun

Daily sunscreen has the best trial evidence for protecting skin from visible ageing (Hughes et al., 2013). We cite no trial on under-eye pigment itself, but it is a sensible step. Apply it around the orbital bone and wear sunglasses.

Sleep, consistently

Sleep experts recommend at least seven hours a night for adults (Watson et al., 2015). Some people find that sleeping slightly propped up reduces morning puffiness.

Treat allergies

If you wake with itchy, swollen eyes or have hay fever, ask a pharmacist or doctor about antihistamines or nasal treatments. Treating the allergy may improve both puffiness and colour.

Use targeted ingredients, gently

• Vitamin C in the morning is a common choice. It is needed to build collagen and shows some benefit on skin (Pullar et al., 2017), but we cite no trial for under-eye colour.
• Niacinamide improved blotchy redness, dark spots and sallowness in a 12-week split-face trial, though it was industry-run and not specific to the eye area (Bissett et al., 2005).
• Caffeine eye creams are widely marketed for puffiness. We cite no trial, so treat the effect as short-lived at best.
• Retinoids boosted collagen-building activity in a 24-week trial on older adults' skin (Kafi et al., 2007) but irritation is the usual side effect, which matters near the eye. Use a product designed for the eye area and introduce slowly. See retinoids for beginners.
• Moisturiser can make the surface feel and look smoother.

Cold compresses

A cool compress for a few minutes may feel helpful for puffiness. It will not change pigment.

Concealer

A colour-correcting concealer is the fastest result. Makeup artists commonly use peach or orange tones to counter blue and brown-purple on deeper skin, and pink-peach tones on lighter skin. That is styling convention. Pat, do not rub.

Professional options

If circles bother you, see a dermatologist or an accredited cosmetic physician. Depending on the cause, they may discuss prescription lightening agents, chemical peels, laser or light treatments for pigment and vessels, or filler for deep hollows.

What to skip

• Cucumber slices and tea bags as a cure. They can feel nice, but they do not fix pigment.
• Harsh scrubs or acids near the eyes.
• Rubbing or pulling at the skin when applying products.
• Unlabelled bleaching creams, which can contain harmful ingredients.
• Constantly changing products. The area is sensitive and needs time and consistency.

Tracking progress

Because lighting changes how dark circles look, judge progress with photos taken in the same place, light and time of day. LookFlex scans include an under-eye brightness read, count a change only when it beats the measurement margin, and warn you when two scans were lit too differently to compare. You can start a free scan on your iPhone to set a baseline.

Give any new routine at least eight to twelve weeks. If circles are sudden, asymmetric, painful or accompanied by swelling or other symptoms, make an appointment with a doctor.
