Zeaxanthin

Zeaxanthin is a carotenoid—a natural pigment produced by plants—belonging to the xanthophyll family. Unlike some carotenoids, your body cannot synthesise zeaxanthin, meaning it must be obtained through diet or skincare products. It is structurally very similar to lutein, differing only in the arrangement of atoms, and is found naturally in leafy greens, corn, and egg yolks.In skincare formulations, zeaxanthin functions as an antioxidant, helping to neutralise free radicals and reduce oxidative stress on the skin.

Zeaxanthin works by quenching free radicals—unstable molecules that form from environmental stressors like UV exposure and pollution. By neutralising these free radicals before they can damage skin cells, the ingredient helps reduce oxidative stress, which is implicated in premature ageing and skin barrier compromise.The ingredient's antioxidant effect extends beyond simple free radical scavenging; research suggests it may also help reduce inflammation in skin tissue, though the precise mechanisms in topical skincare require further investigation.

Zeaxanthin is typically used as part of a broader antioxidant strategy rather than a standalone treatment. It works well in serums, moisturisers, and eye products where it can be combined with other antioxidants like vitamin C or vitamin E for potentially complementary protective effects. Apply to clean skin as directed on the product label.

Zeaxanthin is generally well-tolerated in skincare. As a natural carotenoid, it is not known to cause irritation or adverse reactions in topical use.
