Vitamin K— Are you on an endless quest to find the miraculous ingredient to transform your dull skin into gorgeous skin? So, put an end to your search! 

Today, we’re going into the lovely world of Vitamin K and its numerous skin benefits. 

We investigated everything from its brightening powers to its potential drawbacks. 

Let’s explore the advantages of Vitamin K together!

What Is Vitamin K?

You’ve undoubtedly heard of it, but are you aware of what it can do for your skin? 

Vitamin K is a fat-soluble vitamin in two varieties: K1 and K2. Many leafy green crops, including spinach and kale, contain K1, also known as phylloquinone. K2, or menaquinone, is produced by bacteria in your stomach and can be found in some fermented foods.

Its main functions include bodily functions, blood clotting, calcium regulation, and bone health.

“In dermatology, Vitamin K is used to help promote healing by it’s anti-inflammatory properties, and reduce bruising,” says Dr. Lucy Chen.

Benefits of Vitamin K for Skin

#1. Get Rid of Dark Circles: We’ve all struggled with those bothersome dark circles beneath our eyes. Vitamin K is like a superhero that appears out of nowhere to rescue the day! Its anti-inflammatory characteristics help decrease the appearance of dark circles and puffiness around the eyes, leaving you feeling refreshed and invigorated.

#2. Wound and Scar Healing: Vitamin K is well-known for its exceptional ability to aid in skin healing, including wrinkles. When used topically, it may help diminish scars, bruises, and even redness.

“Topical Vitamin K helps in wound healing by helping the healing epithelial cells move in faster and promote more blood flow to close the wound,” says Dr. Chen.

So, if you’ve been hoping for smoother and cleaner skin, Vitamin K might be the missing element.

#3. Brightening Dull Skin: Do you want a vibrant and glowing complexion? Vitamin K might assist you in achieving that natural glow and skin elasticity. It brightens your skin and gives it a young and healthy appearance that will turn attention everywhere you go!

#4. Capillary Strengthening: Weak capillaries can cause apparent redness and small blood vessels near the skin’s surface. Vitamin K is rescued by strengthening these delicate blood vessels, reducing redness, and promoting an even skin tone.

#5. Fighting Stubborn Bruises: We all get bruises occasionally, whether it’s a clumsy accident or a sports-related injury. Vitamin K’s clotting properties help break down these bruises faster, allowing you to bid farewell to those unsightly marks more quickly.

“Vitamin K cream has been shown to reduce bruising after procedures such as lasers and cosmetic injections,” says Dr. Chen.

Expert Advice

According to National Institute of Health, there are certain recommended intakes of Vitamin K as follows:

Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals.
Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA.

Side Effects Of Vitamin K

The good news is, Vitamin K is generally considered safe for all skin types. However, if you have a history of blood clotting issues, it’s essential to consult your physician before adding Vitamin K to your skincare routine. 

While Vitamin K doesn’t have any known side effects, it’s better to err on caution if you have specific health concerns.

How To Use And Apply Vitamin K

So, you’ve decided to give Vitamin K a shot – great choice! Here are some tips on how to make the most of this wonder ingredient.

“Underye dark circles are more apparent when capillaries and veins are close to the skin’s surface,” says Dr. Chen. “So, you’ll find Vitamin K in eye creams for dark circles and tired-looking eyes.”

Applying it once or twice daily should do the trick. To enhance its brightening effects, look for products that combine Vitamin K with other skin-loving ingredients like caffeine or arnica.
