Micronutrients and Skin Health: The Beginning


Understanding which micronutrients are important for skin and nail health, and maintaining healthy levels of those nutrients, can help prevent some dermatologic conditions. It’s also beneficial if you already have skin conditions arising, you may be able to recognize a possible vitamin or mineral deficiencies. This article is only intended as a starting point, it's always recommended to discuss any major changes with a medical professional you trust. 

There are several micronutrients that play a role in maintaining skin health and preventing dermatological issues:

  • Vitamin C – The antioxidant properties of vitamin C (ascorbic acid) and its role in collagen synthesis make vitamin C a vital molecule for skin health [source]

  • Vitamin D – A 2007 study in the American Journal of Clinical Nutrition demonstrated that telomeres (the caps of genetic material on the free ends of DNA strands which shorten with age) were significantly longer in patients with the highest serum vitamin D levels, compared to those with the lowest … equivalent to five years of aging.

As studies and research continues in the field of micronutrients and skin health, new findings are revealed supporting older studies and also revealing new effects of these micronutrients in the field of dermatology. The articles we write are meant to act as living documents, so as to keep you as up to date as possible with current advancements and information. They are also intended to help spread as much of the helpful information released as possible in order to extend the knowledge and raise the awareness!

These micronutrients will be looked at in individual articles as a series, and will discuss the link between each vitamin or mineral and the skin. Especially highlighting the effects on red, reactive, and sensitive skin.
