Vitamin K2
Vitamin K2 is a fat-soluble vitamin increasingly used in modern skincare formulas for its ability to support skin resilience and brightness. Often paired with retinol or peptides, it helps create a more even, luminous complexion and is popular in targeted serums and eye creams. Shoppers looking for gentle yet effective anti-ageing ingredients are turning to it for a fresher-looking finish.
How it works in skincare
In cosmetic formulations Vitamin K2 works by supporting the skin’s natural processes that maintain healthy microcirculation and reinforce the skin barrier. It helps minimise the appearance of dark circles, redness and uneven tone while working synergistically with other actives to promote a smoother, more radiant texture without irritation.
