About this study
Official title: Skin Microbiome of Chinese Population Cohort Study: Association Between Human Health and Skin Microbiome
This observational study aims to investigate the relationship between public health and the skin microbiome in the province of Zhejiang. Due to the lack of current research on the skin microbiome, the following general questions will be investigated in this study: 1) What connection exists between dietary practices and facial skin microbiome? 2) How do people's lifestyle routines affect the facial skin microbiome? 3) What effects does the altered living environment have on people's facial skin microbiomes? 4) How do the seasons affect people's facial skin microbiomes?
Every 3 to 4 months, the participants' facial skin microbiota samples will be taken, and they will be asked to complete a survey.
- Conditions
- Skin Microbiome
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in facial microbiota profiling
Quantitative and qualitative analysis of bacteria population from the sample, rRNA and metagenome sequencing will be conducted on each sample
Measured: Day 1, Day 90, Day 180, Day 270, and Day 360

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Sep 2026.
