Vitamin K is a fat-soluble vitamin essential for blood clotting and bone health. In skincare, it is particularly favoured for reducing the appearance of dark circles and varicose veins. Discover more about vitamin K below.
Does vitamin K have proven effects on dark circles?
By stimulating blood circulation, vitamin K could potentially reduce the visibility of bluish dark circles. However, while some clinical studies have been conducted on this matter, the scientific evidence remains limited.
Does vitamin K possess healing properties?
Yes, the vitamin K speeds up wound healing, particularly due to its ability to stimulate the epithelialisation process.
Is vitamin K beneficial for hair application?
The antioxidant properties of vitamin K could potentially protect hair fibres from oxidation, thereby delaying the onset of grey hair. However, this has not been scientifically confirmed at present.
What are the different forms of vitamin K that exist?
There are three types of vitamin K : vitamin K1 (phylloquinone, phytomenadione or phytonadione), vitamin K2 (menaquinone) and vitamin K3 (menadione). In cosmetics, it is the oxidised vitamin K1 that is used.
Is the cosmetic use of vitamin K safe?
In some individuals, the vitamin K may cause an allergic reaction. Therefore, it is recommended to perform a patch test when using a new skincare product for the first time.
