A vitamin K derivative. Well tolerated; independent data limited.
Phytonadione Epoxide is a derivative of vitamin K1. Its INCI name is Phytonadione Epoxide. In cosmetics it appears in eye-area formulas linked to dark circles and the marks of small bruises. On efficacy it is worth being honest. The manufacturer links it to fewer bruises and lighter dark circles, but independent data are thin. The evidence base for topical vitamin K on dark circles is weak, so it is more reasonable to see it as a supportive active than a proven fix. Do not expect marked results. Applied topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerance is high, with a low irritation and allergy potential, and it suits the delicate skin around the eyes. Most people see no reaction.
