Polyphenol-Rich Cranberry Beverage Positively Affected Skin Health, Skin Lipids, Skin Microbiome, Inflammation, and Oxidative Stress in Women in a Randomized Controlled Trial
-
Sixteen oz of cranberry juice for 6 weeks.
In conclusion, six weeks of polyphenol-rich cranberry beverage consumption protected skin against UV-induced erythema, improved skin elasticity, and reduced oxidative stress. Most of the skin parameter benefits were observed in women ≥40 years old, whereas younger women were much less responsive. Skin lipids were found to be modulated after both cranberry beverage and placebo consumption, while the skin microbiome was altered at the species and strain level by cranberry beverage consumption. These findings suggest a potential benefit of cranberry beverages on skin health in women ≥40 years old and warrant future studies on this group of women and the mechanism behind this.
