Temporal Variation of the Facial Skin Microbiome: A 2-Year Longitudinal Study in Healthy Adults

Abstract

For healthy people, facial skin microbiome diversity and composition are relatively stable from year to year. Tracking the temporal changes in the microbiome along with skin phenotypic changes allows for a deeper understanding of the skin microbiome's role in health and disease. These results should be helpful in the design of longer-term intervention trials with microbiome-based skin care treatments.
