About this ingredient

Cornflower extract (Centaurea Cyanus Flower Extract) is a water-glycerin or hydro-ethanolic extract of Centaurea cyanus flowers. Active components: anthocyanins (cyanin), flavonoids (apigenin, luteolin), coumarins, tannins. Where applied. Toners, micellar waters, eye-area products, soothing masks. In Spain – Klorane Bleuet, Avène Eau Thermale, La Roche-Posay Toleriane. Decorative cosmetics: eye patches, hydrogel masks. Mechanism. Anthocyanins provide a mild anti-inflammatory and antioxidant effect on dermal capillaries. Tannins give a light astringent action, reduce eyelid puffiness. Effect is mild, supported by ethnobotanical tradition; RCTs are scarce. Evidence base. Direct clinical RCTs on topical cornflower extract are few. In vitro studies (Lockowandt 2019) show moderate antioxidant activity. Real clinical effect at cosmetic concentrations is likely driven by the carrier (glycerin, thermal water) more than the extract itself. Safety. CIR has not issued a dedicated review; the extract has appeared in cosmetics for decades without systemic toxicity reports. Allergic reactions are rare, described in pollen-sensitive patients to Asteraceae (ragweed, chamomile). Does not photosensitize. Pregnancy and lactation – safe topically. Acceptable on face and eye area at any stage. Oral supplements with cornflower in pregnancy are not recommended per EMA HMPC 2014 consensus due to insufficient data. Suitable for. Sensitive skin, redness-prone skin, eyelid puffiness. Does not treat couperose or rosacea – for those there are active ingredients (azelaic acid, ivermectin, brimonidine).
