Anti-Aging Effects of Probiotics

The body of evidence demonstrating the beneficial effects of probiotics on the skin continues to grow in the published literature. Insights into their effects at the molecular level, in animal models, and in human clinical trials build the case for their role in slowing the skin manifestations of both intrinsic and extrinsic aging. The reports reviewed in this manuscript demonstrate that probiotics can restore acidic skin pH, alleviate oxidative stress, attenuate photoaging, improve skin barrier function, and enhance hair quality.
