Spermidine-induced recovery of human dermal structure and barrier function by skin microbiome

摘要

a Relative abundance (RA) of facial skin microbiome at the genus level including some clinical information. The top 10 most abundant genera are presented. Violin plot and boxplot show the RA of each skin microbiome with the columns sorted by age. b Boxplot illustrating the RA of the Streptococcus genus in old (n = 26) and young (n = 26) participants. c Taxonomic plot of LDA scores from LEfSe, illustrating the sequenced microbiome that differed significantly at least at the genus level between the old and young group (|LDA score| > 3.5); g, genus; s, species. d Boxplot illustrating the elasticity index of the old and young groups. Wilcoxon–Mann–Whitney test and Pearson correlation test were used for statistical analysis. e RA of Streptococcus versus normalized elasticity index of the old and young groups.
