Short, intense sun seeking trips can disturb skin's microbiome - Video

Overview

Skin, the largest organ of the human body, is home to a vast array of bacteria, fungi, and viruses-microorganisms that compose the skin microbiota. Among other things, these microbial populations, which are organized in complex community structures, protect against pathogens. Prolonged exposure to UVR is associated with damage to DNA in skin cells, inflammation, and premature skin aging, yet intentional sun-seeking behaviors remain common.

Due to a lack of studies focusing on how individual behavior influences UVR-associated microbiota shifts, and how this may relate to skin health, researchers in the UK have now examined the effects of sun-seeking behaviors on the skin microbiota composition of holidaymakers.

Prior to vacations to sunny destinations, which lasted at least seven days, the researchers analyzed participants’ skin. The skin microbiota is largely made up of three bacterial communities on the surface: Actinobacteria, Proteobacteria, and Firmicutes. On day one, 28, and 84 post-holiday, participants’ skin microbiota was assessed again.

Dr Thomas Willmott, the study’s first author explained, “This study was performed in real-life holidaymakers and provides important insights into how sun exposure resulting in a tanning response – even over a relatively short sunny period – can lead to an acute reduction in Proteobacteria abundance, which decreased skin microbiota diversity.”
