A study published in the October 2009 issue of the International Journal of Cosmetic Science found that antioxidant supplements may help keep aging skin healthy, vibrant and smooth.
Researchers recruited 60 women between 35-65 years of age for the double-blind, placebo-controlled trial.
The women were randomly assigned to receive an antioxidant supplement or a placebo for 12 weeks.
The supplement contained a number of antioxidants including coenzyme Q10, beta-carotene, grape seed extract, French maritime pine bark extract and green tea extract. The supplement also contained the minerals zinc and selenium.
The researchers measured the level of skin roughness and wrinkles at the beginning of the 12 week study period and once every 4 weeks until the end of the study.
At the beginning of the study there was no difference in skin roughness or wrinkles between the two groups.
By the time the researchers measured skin roughness and wrinkles again at the 4 week mark, there were already significant reductions in roughness and wrinkles among the antioxidant group.
By the end of the study, skin roughness and fine wrinkles had reduced by 21% in the antioxidant group and less then 2% in the placebo group.
Using questionnaires the researchers were also able to find a self reported reduction in pore size, skin roughness and fine wrinkles and the antioxidant group was significantly more satisfied with their skin at the end of the study.
This study adds to a growing body of evidence linking antioxidants with skin health and more vibrant, young looking skin. A number of cosmetic creams now use antioxidants but this study shows that oral forms may be just as effective.
Taking antioxidant and mineral supplements orally may also provide you with a large list of other health benefits such as reduced risk of cancer, cardiovascular disease, cognitive impairment and Alzheimer’s disease.
