Vitamin D And Skin

We’ve been hearing whispers of a vitamin D acne connection for several years now.  We all know that vitamin D is the “sunshine “ vitamin and that it is good for your bones.  At the same time we’ve also been warned to always wear sunscreen and limit sun exposure for fear of premature aging and developing skin cancer.  However more and more evidence is now cropping up, proving a vitamin D acne correlation.  Vitamin D can reduce inflammation which means that it can be very helpful to those with acne and other skin problems.  But who should we believe and what should we do?

What Is It?

Vitamin D is a steroid vitamin, a group of fat soluble pro hormones which encourage the absorption and metabolism of calcium and phosphorus.  There are 5 forms of Vitamin D but only 2 forms matter to humans - D2 (ergocalciferol) and D3 (Cholecalciferol)  Vitamin D is synthesized in the skin from cholesterol on exposure to the sun.  It can also be obtained from food and supplements. 10-15 minutes of sun exposure 2 times a week on the face, arms, hands or back without sunscreen is necessary for adequate amounts of Vitamin D3.  Longer exposure times do not produce more vitamin D and increases the risk of sunburn, premature again and skin cancer.

Vitamin D Acne Benefits

Vitamin D is antimicrobial.  It can stimulate the production of cathelicidans which are natural antibiotics.  These kill the P.acnes bacteria and prevent acne from occurring.  The antioxidant properties of Vitamin D protect skin cells from oxidative stress, a key component in the cause of acne. Vitamin D is protective, shielding epidermal cells from UV radiation and exposure to chemotherapy.

In a 2008 study led by Richard Gallo M.D. Phd. Division of Dermatology at UCSD School of Medicine, researchers discovered that vitamin D supplementation supports the production of protective chemicals, which in turn helps prevent infections of the skin.  It has been noted that acne can become worse during Winter when most of us do not get enough sunlight.  It was brought to light in a 2006 study by J Reichrath et al. that vitamin D suppresses sebaceous gland activity and cell proliferation – less oil and less skin production of skin cells means less acne.

The Vitamin D acne benefits extends to its anti-inflammatory properties.  But since it is dose dependent, with too much making its effects negative, more studies are necessary to understand the full extent of its capabilities.
