Microbiome Comparison Profile of Normal Skin and Acne Vulgaris Patients

Microbiome Comparison Profile of Normal Skin and Acne Vulgaris Patients

The aim of this study is to compare the profile of the microbiome on normal skin and acne vulgaris patients. A cross sectional study with 144 samples, male or female between 18-40 years old, from January to May 2023.

Recently, research on the role of the microbiome in the process of acne vulgaris has continued to grow. Seeing the important role of the microbiome in maintaining the balance of skin health, this study aims to compare the profile of the microbiome on normal skin and on acne vulgaris patients, in order to gain a deeper understanding the role of the microbiome in acne vulgaris and also to compare skin microbiome features in various degrees of acne vulgaris severity. This research is an observational study with a cross sectional design. Subject selected by consecutive sampling, with total 144 samples consists of males and females age 18-40.

There will be two visits in this research. The first visit, for screening patients with requests for informed consent, giving facial soap, screening for inclusion and exclusion criteria, screening for facial skin complaints and facial care habits, collecting data on patient demographics and medical history, physical examination, sebumeter examination to measure sebum levels on facial skin, and taking clinical photos for documentation. The second visit is collecting microbiome data which will be taking in 1 to 2 weeks after the first visit. Using swab method to take microbiome samples, after that, there will be DNA extraction, amplification and sequencing were carried out on the sample and the Shannon Index will be calculated. Then, the data will be tabulated and analyzed according to the hypothesis.
