A more uncommon skincare ingredient in the vitamin world is vitamin K, which is mainly hailed for aiding the body’s process of healing wounds. But could ‘K’ prove another important link when it comes to building an iron-clad defense against anti-aging? The vitamin is a rather intriguing one—a study on vitamin K even confirmed that ample vitamin K intake can help you live longer. We asked dermatologists to break down the vitamin and its various health properties.
According to Yunyoung Claire Chang, MD, a board-certified cosmetic dermatologist at Union Square Laser Dermatology in New York City, vitamin K—mainly found in green leafy vegetables like spinach, kale, collards, and swiss chard—is best described as an essential fat-soluble vitamin that plays an important role in blood coagulation (inhibiting excessive bleeding), blood calcium regulation, and overall bone health.
“Additionally, lab and animal studies have found that vitamin K can reduce the production of pro-inflammatory proteins (called cytokines), therefore working as an anti-inflammatory,” says Dr. Chang. “Both animal and human studies have shown topical vitamin K to help with wound healing, potentially due to its antioxidant or blood-clotting properties.”
