The Power of Antioxidants: Achieve Radiant Skin

Wednesday June 27, 2018

 


Familiar with the buzz word? Antioxidants are naturally occurring compounds found in a plethora of colourful fruits and vegetables, that work to protect cells against harmful oxidative damage, which may augment the development of diseases and health issues. Many antioxidants have been highlighted to promote skin health, such as Vitamin E, Vitamin A (including carotenoids).  


Vitamin E:


A fat-soluble vitamin that is critical for skin maintenance and protection, vitamin E is a frequently used ingredient in skincare products and supplements for a reason. Functioning as an antioxidant, vitamin E can absorb and prevent UV damage to the skin, that may contribute to premature ageing and skin irritation. Furthermore, vitamin E can may exert anti-inflammatory benefits to reduce skin swelling and oedema. Due to these suggested effects, vitamin E supplementation has been used extensively to help treat chronic inflammatory skin conditions (1). Acting as a vital role to the skin's defences, vitamin E supplementation may promote healthy skin maintenance and integrity. 


Vitamin A (Beta Carotene):


Vital to healthy skin cell production and natural defence, vitamin A is another exceptional antioxidant that plays a central role in the skin. Vitamin A is classified into a group of compounds, including carotenoids, retinol, retinoic acid and retinal. Carotenoids (including beta-carotene) is the form that is found in dietary sources or supplements. The body then converts beta-carotene to the active form of vitamin A in the body for use. Exhibiting photoprotective benefits, vitamin A may help protect the skin against UV damage that may break down collagen, integral to skin structure. Furthermore, not getting enough vitamin A can contribute to weakened skin, dryness, and impaired wound healing. As vitamin A can also stimulate cell turnover, it may reduce the likelihood of clogged pores that contribute to acne.


Zeaxanthin:


Another carotenoid that is naturally occurring in dietary sources, zeaxanthin is present in abundance in the skin and eyes, which has been shown to help reduce light-induced skin damage in research (2). Specifically, research displays that oral supplementation with zeaxanthin may help reduce sunburn cell formation and inflammation (2).  Furthermore, oral supplementation of zeaxanthin and lutein can contribute to an improvement in overall skin tone, according to a recent trial (3). After 12 weeks of supplementation, volunteers experienced improved luminance and skin condition compared to placebo.


Conclusion:


Not only do antioxidants show potential for optimal skin health, they are integral in the protection against chronic diseases. To support your diet, you may wish to supplement with fat-soluble antioxidants to promote skin maintenance.
