We know we’ll still feel hungry after eating a big bag of chips. But when has that ever stopped us from going arm-deep into that bag until we see the end of it? Similarly, the fact that genetically dark under-eyes can’t be completely treated doesn’t mean we give up. We have vitamin C, niacinamide, caffeine, and licorice extract in our arsenal. And now, the best vitamin K eye creams strengthen our hands to better target dark circles and discoloration under the eyes.
Vitamin K is being incorporated into more and more skincare products, especially eye products. But is the science behind it solid? I found out.
But before I deliver, remember that the narrative changes notably when you talk about an ingredient in the context of diet as opposed to topical skincare.
As always, we’re going to focus on the latter and talk about vitamin K in topical skincare products.
What is Vitamin K?
Vitamin K, also known as vitamin K1, phytonadione, phytomenadione, is a fat-soluble vitamin (1). It’s commonly found in green plants. It’s been increasingly popular and usually found in skincare products formulated to target dark circles under the eyes.
Vitamin K on its own is an important nutrient. In your body, it helps your wounds heal properly (2). But the fact that it’s beneficial when ingested does not mean the same benefits apply when used topically as skincare.
Compared to other vitamins we use in skincare such as vitamins C, E, or A, vitamin K lacks a significant amount of research confirming its benefits for your skin.
Does Vitamin K Really Help with Dark Circles?
Yes and no. Follow me here. The hype behind vitamin K can be traced back to its wound-healing properties, especially bruising. The studies about vitamin K and its benefits on the skin are mostly about patients who have gone through skin treatments (3) like lasers.
As a side note, these facial treatments are controlled trauma to the skin and sometimes you can deal with post-procedure redness and bruising. These studies suggest that vitamin K accelerates the healing of bruising (purpura) after treatments.
The keyword here is bruising! Dark circles are not bruises! They do not happen as a result of an injury. To test this out, there’s another study where participants used vitamin K before the laser treatment to see if vitamin K prevents bruising.
We can assume it was to see if it helps with discolorations such as dark circles even if there’s no trauma to the skin. The study concludes that vitamin K did not prevent bruising but accelerated healing after the bruising occurred (4).
Even though it seems like vitamin K is not such a big deal, it may very well be. Because there are other things that can cause/worsen dark circles.
These include lack of sleep, allergies, stress, tiredness, and even excessive crying that causes the tiny blood vessels to break and give you red and purple spots under the eyes.
Also, the fact that vitamin K helps with broken capillaries, bruising, and swelling makes it a great option for people who are dealing with rosacea flares and under-eye discolorations that are not due to genetics. These are the concerns vitamin K seems to be more useful for.
Plus, vitamin K eye creams are sometimes paired with other potent brightening ingredients like vitamin C and retinol, which increase effectiveness. Whether it’s genetics or not, there’s no harm in trying as long as you manage your expectations.
