UV exposure to skin generates Vitamin D, a hormone essential to health and preventive of a variety of cancers.

Reduced sun exposure carries with it one substantial but easily-mediated risk: Vitamin D deficiency.

Recent studies have shown that Vitamin D prevents cancers, such as prostate and lung cancer, however Vitamin D does not appear to protect against skin cancer.

In fact, although sunscreen is presumed to reduce Vitamin D production in the skin, some studies have shown that this is not the case.

When sun shines on skin Vitamin D (a hormone which has been labelled a Vitamin because it is essential to health) is produced.

Patients often cite the potential for Vitamin D deficiency as a reason not to use sunscreens in the treatment for their rosacea, or worse, to gain additional sun exposure.

If you must expose yourself to the sun, there is no reason to use your face for the exposure.

Less frequently exposed areas of skin usually produce Vitamin D more efficiently than areas which have sustained more sun damage.

It is worth noting that sun exposure does not guarantee that you will not become Vitamin D deficient.

Sun damage from exposure appears to reduce the skin's efficiency at producing Vitamin D and while it is not very common, it is not unheard of for dermatologists to find heavily sun exposed patients deficient in Vitamin D.

Foods naturally high in or fortified with Vitamin D can be used in place of UV exposure.

The solution is simple — take a 1000 i.u. daily Vitamin D supplement (either alone or as part of a combination supplement), or make a point of eating foods containing Vitamin D or Vitamin D-fortified foods.

Vitamin D supplement (liquid form) from Ostelin.

A blood test should be made to verify your Vitamin D levels are high enough.

By taking 1000 i.u. daily it is highly unlikely that you'll be deficient, however you should still verify your levels after a month of supplementation and periodically thereafter.

You should be reassured that the upper limit of daily Vitamin D supplementation is 30x more than the recommended daily supplementation.
