Vitamin K

Description

Vitamin K is a fat-soluble vitamin that plays a crucial role in blood clotting and skin health. In skincare formulations, it is primarily used for its potential to address various dermatological concerns. Vitamin K exists in two main forms: phylloquinone (K1) and menaquinone (K2), with K1 being more commonly used in topical applications.

This vitamin exhibits potent anti-inflammatory properties, making it beneficial for reducing redness and swelling associated with various skin conditions. It is particularly effective in treating bruising and post-procedural ecchymosis due to its ability to strengthen capillary walls and promote faster healing. Vitamin K has also shown promise in addressing dark under-eye circles by improving microcirculation in the delicate periorbital area.

In skincare formulations, Vitamin K is often combined with other active ingredients like retinol or Vitamin C to enhance its efficacy. It is typically incorporated into serums, creams, and eye treatments at concentrations ranging from 1% to 5%. While generally well-tolerated, some individuals may experience mild irritation or allergic reactions. As with any active ingredient, patch testing is recommended before full application to ensure compatibility with individual skin types.
