Five Fast Vitamin K Facts
Vitamin K is popular in under-eye creams because it can lighten infraorbital darkness, AKA under eye circles. It is most beneficial for circles with a blue or brown undertone.
- Vitamin K reverses the calcium deposits in elastin fibers. These deposits harden and cause wrinkles.
- Vitamin K helps with blood coagulation and circulation.
- Vitamin K is also called Phytonadione on ingredient listings.
- Some dark circles are caused by weak vessels that allow blood near the surface of your skin. These circles have a blue, purple or brown undertone.
- Topical application of vitamin K cream prior to an in-office procedure strengthens blood vessels. Stronger blood vessels means less bruising after surgical or laser treatments.
What to look for in a Vitamin K Topical
Vitamin K is most effective as part of a team instead of a standalone K cream or gel. A study in the Journal of Cosmetic Dermatology showed topical Vitamin K works best when paired with retinol, Vitamins C, E, and the Bs. (1)
If you use prescription retinol, apply the retinol first and then the topical K product.
Choose a product with enough Vitamin K to be effective. The study used a 2% Vitamin K concentration.
