About
To evaluate whether personal care products shift the skin microbiome bacteria and diversity after a week of daily use.
Full description
Studies have shown that microbiome is important in skin conditions such as eczema, rosacea, acne, and many other skin conditions. Personal care products are widely used on a daily basis but it is not know how these personal care products shift the skin's microbiome. The diversity of the skin microbiome is important in the maintenance of skin equilibrium as a loss of diversity predisposes to development of skin disease.
The aim of this study is to evaluate multiple over the counter products that are used on the face daily to assess how they alter skin microbiome and diversity of microflora on skin after a week of daily treatment.
A second aim of the study is to assess how baseline diversity of microbiome are different based on self-graded skin types.

- Individuals who have participated in any other clinical studies using the same test sites (face) in the past 14 days
Exclusion criteria
- Individuals who have been on any topical antibiotic for the past one month or oral antibiotic therapy for the past 2 months or are currently on any antibiotic therapy
- Individuals who have history of acute or chronic disease that would likely interfere with or increase the risk on study participation at the discretion of the investigator
