About





            

                
Vitamin K is a fat-soluble vitamin essential for blood coagulation that may support skin healing and reduce bruising. Topical vitamin K has been studied for dark circles under the eyes. Oral supplementation for skin has minimal clinical evidence, though K2 is being investigated for elastic fiber calcification prevention.

            

        

        

        
        
        

            

  
How It Works





            

                
Fat-soluble vitamin essential for blood coagulation (carboxylation of clotting factors); may support skin healing and reduce bruising; vitamin K-dependent proteins (Gas6) are involved in skin cell proliferation; topical vitamin K may reduce dark circles by strengthening capillary walls.
