Protecting the skin with nutrition

Our skin may be the first line of defence but it is under constant attack from the moment we wake up.

Air pollution (traffic fumes, air conditioning/heating systems, city dirt) sun exposure, ultraviolet (UV) B rays and free radicals generated from toxins such as cigarette smoke all have an impact on our skin health. Even chemicals in cleaning agents and body care products are putting the skin - the human body’s largest organ - under threat.

Whilst you may have little control over the environmental factors, we can learn how nutrition can play a role in protecting the skin tissue from premature aging, infection, imbalance and chronic conditions.  

Here are some key nutrients which play an important role in skin health:


- Consider carotenoids – often found in bright red, yellow and orange fruit and vegetables. Carotenoids are a family of phytonutrients known to quell free radical attack, contribute to membrane stability and structure, offer protection from the effects of sun burn and disrupt in-body repercussions of UV-B sun exposure[1] [2].  Check the nutritional panel for; beta carotene, mixed carotenoids, lutein and zeaxanthin. 

- Look for Astaxanthin. Vegan Astaxanthinis sourced from microalgae and is an important member of the carotenoid family. This nutrient has produced phenomenal results for skin and DNA protection from the effects of UV rays[3].


- Grape seed extract is a major source of oligomeric proanthocyanidins (OPCs); a compound that is reported to have a significantly greater anti-oxidant potential than vitamin C or vitamin E[4].  This protective effect has the potential to support the collagen matrix, protect against free radical damage and reduce inflammation and infection[5] [6].

- Superoxide dismutase (SOD) – the ‘enzyme of life’. Skin health is reliant on the potent anti-oxidant effects of Superoxide dismutase (SOD)[7], an enzyme produced by our bodies alongside free radicals. This is possibly a self-preservation action and consequently is known as the ‘enzyme of life’.  However, production of SOD reduces with age[8], making SOD supplementation an important element of protection.

Unfortunately there isn’t a nutrient that can protect from the pain, inflammation and redness of sunburn.  Therefore, an ethical, certified organic sun screen should always be used, especially during the period when the sun is directly overhead.  

Is there ever a time when the skin does not need protection?  Probably not, but it is worthwhile considering making small changes to your diet to support your skin health.
