Whilst sunscreen is essential, it is important to remember the significance of nourishing our body with vital nutrients and not to overlook your diet.
When UV rays from the sun come into contact with your skin, they can create what is known as ‘free radicals’. Free radicals are active molecules creating a chain reaction of skin inflammation and damage, which could result in premature skin ageing and other skin health issues.
Studies have shown that adding anti-inflammatory antioxidants to your skincare regimen can protect the skin by reducing free radical production and restoring the skin from oxidative stress. Antioxidants have been found to effectively fight free radical damage by interacting and neutralising free radicals, helping to protect your skin against damage and keep your complexion looking fresh and radiant. Incorporating the following simple tips can help to keep your skin in good health when you travel and preload your body with antioxidants. Four nutrients that have been found in clinical evidence to help support overall skin health, due to antioxidant properties are astaxanthin, grape seed extract, superoxide dismutase (SOD) and beta carotene.
Astaxanthin
Astaxanthin is a red pigment which belongs to the xanthophyll carotenoid group naturally found in sources such as salmon, algae and crustaceans. Astaxanthin is cultivated from Haematococcus pluvialis, located close to the ‘Stone Forest’ using natural waters from the Himalayas. Astaxanthin’s antioxidant and anti-inflammatory properties have been demonstrated in a number of studies. In a clinical trial, it was found that astaxanthin significantly suppressed the secretion of inflammatory cytokines caused by UV exposure after 16 weeks of 6-12mg supplementation (1). Inflammatory cytokines are signalling molecules, which are released by the body’s immune cells and promotes inflammation as part of its ‘defence’ response.
Grape seeds
Grape seeds contain naturally occurring antioxidants that can help protect cells from free radical damage. It has been scientifically proven to improve the overall health and appearance of the skin, smooth skin, reduce wrinkles, prevent ageing skin, and protect against oxidative damage generated by UV rays. It was found that supplementing with grape seed extract can improve skin pigmentation, particularly around the summer months (2).
Superoxide Dismutase (SOD)
Superoxide Dismutase (SOD) is a group of enzymes that help catalyse reactions involved in the dismutation of superoxide radicals, thus protecting the cells against oxidative stress Surprisingly, the antioxidant enzyme, Superoxide Dismutase known as SOD, is naturally occurring in a variety of cantaloup melon.
SOD is required as the first line of defence against the formation of free radicals that can contribute to cellular damage. A clinical study found that SOD may help prevent DNA damage to skin cells caused by UV-induced oxidative stress. Therefore, SOD supplementation can significantly increase endogenous antioxidant enzyme activity and reduce sunburn cell formation in response to UV radiation (3).
Carotenoids
Carotenoids are a class of red/orange widespread pigments that are naturally abundant in nature, fruits and vegetables, with over 600 carotenoids present. They are present in carrots, sweet potatoes and butternut squash. In addition to serving as an antioxidant, beta carotene is recognised as a dietary source of provitamin A, meaning that the body can convert it into vitamin A. Beta carotene has been reported to act as a natural pre-tanning aid and protects the skin from any potential damage against UV damage (4).
Conclusion
Supplements are not a replacement for sun protection but should be used as a bonus in addition to regular sun protection. The best ways to protect yourself from the sun include avoiding intense sunlight, wearing sun-protective clothing, and using broad-spectrum sunscreens.
Finally, choosing a quality supplement is vital. All the nutrients used in food supplements should meet US Pharmacopeia (USP) standards - this is the gold standard in food supplement nutrients. Opt for supplements that avoid non-nutritive substances, for example, fillers, flow agents, bulking agents, colours and flavours and only 100% active ingredients.
