Healthy Microbiome Plays a Role in Skin Aging, Researchers Say

Numerous factors contribute to skin aging, including environmental, genetics and lifestyle.

Researchers at the Center for Microbiome Innovation (CMI) at the University of California San Diego (UC San Diego) and L’Oréal Research and Innovation discovered the skin microbiome could hold the key to understanding how the skin ages.

Their findings were recently published in Frontiers in Aging.

For the study, the research team analyzed 13 previous L’Oréal studies, which included skin clinical data of more than 1,000 female participants ages 18–70.

Researchers found a link between skin microbiome diversity and, generally viewed as a key sign of skin aging. They also found a negative association between microbiome diversity and transepidermal water loss, which is the moisture that evaporates through the skin.

“The microbial markers and aging signs identified in this study will steer future research, enabling the generation of larger, more harmonized data to accelerate our understanding of the microbiome in the context of healthy skin and skin aging,” Dr. Zheng, Head of Advanced Research, North America at L’Oréal, noted.

A growing body of research suggests it may be beneficial to focus on skin health and gut health. Researchers continue to explore the connection between the gut and skin and whether a healthy gut could lead to healthier, more youthful skin.
