14 Dec 2023 --- New research investigates how environmental stressors per region affect the skin’s microbiome. Characterization of the skin microbiome of individuals from different geographic regions will help to understand the factors behind the prevalence of skin disorders and support skin care product development, suggest the researchers.

The study highlights the effects of geographic factors on skin microbial structures and skin lipids, especially fatty acids and ceramides.
