| Résumé : |
- Objective :The present study investigated the relationship between the skin bacterial and fungal microbiomes and skin pH at sebaceous sites, namely, the forehead, cheek and upper chest. We also examined the relationship between the skin microbiome and transepidermal water loss (TEWL), which is an indicator of rough skin.
- Methods : Thirty healthy Japanese subjects (15 females and 15 males) were enrolled as subjects. The forehead, cheek and upper chest were examined in August (summer) and February (winter). Skin surface samples were collected using the swab method, and the 16s rRNA and ITS regions were analysed using next-generation sequencing. Skin pH and TEWL were also assessed.
- Results : The changes observed in the skin microbiome were associated with season-dependent changes in skin pH. An increase in skin pH at the forehead and cheek was associated with a higher relative abundance of Cutibacterium spp., a reduction in bacterial diversity, and a lower relative abundance of Staphylococcus spp. A decrease in skin pH at the upper chest was associated with a higher relative abundance of Malassezia restricta, a lower relative abundance of M. sympodialis and decrease in fungal diversity. Moreover, these changes were also associated with an increase in TEWL.
- Conclusion : The present results indicate that changes in skin pH are associated with changes in the skin bacterial and fungal microbiomes at sebaceous sites. The changes observed in the skin microbiome were also associated with rough skin. |
