Abstract

Objective

Exploring the effects of age on microbial community structure and understanding the effects of chronological ageing as well as sun exposure on microbial community diversity.

Method

The microbial characteristics of the facial skin of 98 adult women aged 18–70 years were studied using 16S rRNA gene sequencing, and differences based on age and reported sun exposure were assessed.

Results

The cheek skin's bacterial diversity and richness increased with age. The relative abundance of Cutibacterium decreased with age, while the relative abundance of Corynebacterium, Anaerococcus, Paracoccus, Micrococcus, Kocuria, Kytococcus, and Chryseobacterium increased. In addition, an increase in Micrococcus and a decrease in Cutibacterium were observed in volunteers with more than 2 h of daily sun exposure compared to volunteers with <2 h of daily sun exposure. Under low-sunlight conditions, Cutibacterium was more prevalent in the youth group, and Corynebacterium, Anaerococcus, and Kytococcus were more prevalent in the older group.

Conclusion

The diversity and composition of the bacterial community on the cheeks are affected by age and extrinsic factors (sun exposure) may also play a role in this.

北京地区健康女性面部皮肤细菌组成与年龄有关的变化。

目的探索年龄对微生物群落结构的影响，并了解年龄增长和日晒对微生物群落多样性的影响：方法：采用16S rRNA基因测序法研究了98名18-70岁成年女性面部皮肤的微生物特征，并评估了年龄和日晒对微生物群落多样性的影响：结果：脸颊皮肤细菌的多样性和丰富度随着年龄的增长而增加。Cutibacterium 的相对丰度随着年龄的增长而下降，而 Corynebacterium、Anaerococcus、Paracoccus、Micrococcus、Kocuria、Kytococcus 和 Chryseobacterium 的相对丰度则有所上升。此外，与得出结论的志愿者相比，每天晒太阳超过 2 小时的志愿者体内的微球菌增加，而 Cutibacterium 减少：脸颊细菌群落的多样性和组成受年龄影响，外在因素（日晒）也可能在其中发挥作用。

期刊介绍： The Journal publishes original refereed papers, review papers and correspondence in the fields of cosmetic research. It is read by practising cosmetic scientists and dermatologists, as well as specialists in more diverse disciplines that are developing new products which contact the skin, hair, nails or mucous membranes. The aim of the Journal is to present current scientific research, both pure and applied, in: cosmetics, toiletries, perfumery and allied fields. Areas that are of particular interest include: studies in skin physiology and interactions with cosmetic ingredients, innovation in claim substantiation methods (in silico, in vitro, ex vivo, in vivo), human and in vitro safety testing of cosmetic ingredients and products, physical chemistry and technology of emulsion and dispersed systems, theory and application of surfactants, new developments in olfactive research, aerosol technology and selected aspects of analytical chemistry.
