What causes pigmentation under the eyes?

Pigmentation means extra melanin, the substance that gives skin its colour. Under the eyes, pigment can follow eczema, contact dermatitis or repeated rubbing and scratching. Pigment left after inflammation is called post inflammatory hyperpigmentation. Sun exposure and inherited traits can also contribute.123

Brown circles often have a pigment component, while blue, pink or purple circles can involve visible blood vessels; hollows create shadows, and several causes can coexist. Age related loss of fat can deepen those hollows. A brightening cream does not fill a hollow, however ambitious its job description.45

How to reduce the look of pigmented dark circles

  1. 1Start with the trigger. Stop rubbing your eyes. If itching, eczema or a product reaction keeps the area irritated, get help addressing that cause before adding a lightening treatment.
  2. 2Protect the area every day. Use SPF 30 or higher sunscreen and UV protective sunglasses. Avoid prolonged exposure during the strongest sunlight.
  3. 3Choose treatment for the actual cause. A dermatologist can assess whether pigment is near the surface or deeper in the skin and whether shadows or blood vessels also contribute.
  4. 4Use concealer if you want coverage while treatment takes effect. Makeup hides the colour rather than removing pigment, which is a more modest job than most eye cream advertising offers.

Can skincare help under eye pigmentation?

Vitamin C creams and hydroquinone can help lighten dark circles. Other pigment treatments include kojic acid, azelaic acid and topical retinoic acid. However, eyelid skin is sensitive, stronger products can irritate it, and pigment deeper in the skin responds poorly to creams. Do not assume a facial dark spot treatment is suitable for your eyelids: choose an appropriate product and application instructions with a dermatologist.134

Choose gentle, fragrance free skincare. Stop a product if it burns or stings. Hydroquinone can irritate the area and cause further darkening through inflammation, so pushing through irritation can work against the result you want.267

How to prevent dark circles from getting darker?

For pigmentation, particularly in darker skin tones, tinted sunscreen containing iron oxide adds protection from visible light that can worsen dark spots. Choose broad spectrum, water resistant SPF 30 or higher. Apply sunscreen before going outdoors and reapply every two hours, and after swimming or sweating. Add sunglasses, a wide brimmed hat and shade. Continue managing the irritation that started the pigment; fading existing marks does not prevent new ones if the trigger remains.67

How long does fading take?

As general guidance for post inflammatory pigmentation, a mark a few shades darker than your skin usually fades within 6 to 12 months after its cause stops. Deeper pigment can take years. These are general dark spot timelines, not a fixed schedule for under eye circles. Inherited circles are particularly resistant to treatment. Cold compresses help swelling or prominent vessels, rather than targeting pigment.126

When should you see a dermatologist?

Seek an assessment if dark circles persist despite care or you are considering stronger treatment. Chemical peels can target surface pigment, while lasers are an option for deeper pigment. These procedures require an experienced clinician because incorrect technique can make circles more prominent. Contact a healthcare provider if darkness or swelling affects only one eye, or swelling is excessive.123
