Why Does Vitamin D deficiency Cause Oily Skin?

More and more people are finding Vitamin D deficiency to be the cause of their acne. For some of these people, Vitamin D supplementation has been found to reduce oiliness of their skin resulting in clear, acne-free skin.

But does Vitamin D deficiency cause oily skin? And if so, why?

From My Experience….

There is not much information available on Vitamin D and skin oiliness, so I can only hypothesize based on my own personal results and the limited information provided. Vitamin D has reduced the oil on my skin to a great extent and cured my acne. I believe it is because the oil that is over-produced in my skin when I am Vitamin D deficient is an oily cholesterol that contains Vitamin D precursors. You could call it “Vitamin D Making Oil”. These precursors contained within this oil need to react with the sun to produce Vitamin D which your body can use. I believe when you are deficient in Vitamin D, your skin overproduces this “Vitamin D Making Oil” in an attempt to produce more useable Vitamin D. It then clogs your pores and causes acne.

How Humans Produce Vitamin D

Humans get their Vitamin D from the sun by producing a cholesterol that sits in the very top layer of our skin, the epidermis. The cholesterol then reacts with UV radiation to produce Vitamin D which then gets absorbed into our circulatory system and used by our bodies. (Source: Vitamin D and Skin Health) Cholesterol is described as a fatty and waxy substance. Is it possible that this is the substance clogging the pores of acne-sufferers? To answer that question I’ve researched how animals produce their Vitamin D.

Many furry/hairy mammals cannot actually absorb vitamin D through their skin and instead produce Vitamin D in an oil that sits on top of their skin and in their fur. Because their fur blocks the re-absorption of the oil into their skin, they must then ingest the Vitamin D through grooming. To produce vitamin D, sheep create a yellowish waxy substance called lanolin (also known as “wool wax” or “wool grease”). Lanolin contains high amounts of vitamin D and is used to create many Vitamin D supplements!

Birds also secrete oil onto their feathers in order to produce Vitamin D, although how they go about this is still debated. One compelling theory is that the uropygial gland (an oil-containing gland, found on most birds and used for preening) contains cholesterol Vitamin D precursors (among other substances) that the birds spread onto their feathers in order to produce Vitamin D through contact with UV rays. This gland is also believed to provide an oily water-proof coating for aquatic birds. (Source: The Oil Glands of Birds).

Interestingly enough these glands can sometimes get clogged, crust up and become infected, much like pores can get clogged with oil to produce acne infections. If this happens to a domesticated bird, the gland can be declogged using a warm compress. Kind of sounds like acne doesn’t it? Google “clogged uropygial gland” and you will find that they look an awful lot like a pimple.

Is “Vitamin D Producing Oil” what’s clogging our pores?

The key words here are oil and skin. Scientists have long attributed acne to an over-production of oil. However an explanation for this oil overproduction has never been found. I believe the culprit to be “Vitamin D Making Oil” in our skin.

My hypothesis is that the over-production of this oily Vitamin D producing substance in Vitamin D deficient people causes the oily cholesterol to accumulate in the skin, clogging the pores and then causing acne.

  1. Hey! I will try this. Uour explanation sounds rational and actually stumbled upon the vitamin d thing before reading this. I have bad oily skin. Okay. Theres two things i realized: after being outdoor all day my skin always looked so pretty. I always thought it was the freshness of air but might be it was the vitamin d i produced. Yet, i cannot stay outdoor all day every day. I live in germany, my mum is from the philippines and i’m actually darker than my siblings (they have no oily skin). Also i wear loads of makeup daily and high suncreen whenever i go out on a hot day. So i believe the vitamin d thing could be my cure… omg i’m now actually awaiting a miracle… because it makes so much sense! Yeah and thanks for the explanation!

      1. I dont know if it helped. I took a supplement (about 5000 units per day) and since then my skin has been suspiciously unproblematic! I broke out last week… I don’t know it’s also because I forgot to bring my supplements to my parents during vacation… so far, they seem perfect. I will keep on taking them also because I have tan skin and live in Germany! Regards!
