Simplify your Study Protocols with our Tailored Candidate Recruitment
Highlight your specific requirements for clinical test subjects and we will take care of the entire candidate recruitment process for you, whether it is in-person or remote. This allows us to closely supervise and guarantee the quality of microbiome collection.
10,000+ Subject Database
We offer candidate recruitment across a diverse pool of candidates to give better insights into how certain formulations work with individuals of different backgrounds.
In Lab or Remote Testing
The nature of our recruitment process is often linked to at-home testing, however, if you would prefer a controlled environment to test participants, we can arrange for testing to be conducted within our labs in Singapore, London and New York City.
Simplified Recruitment Process
As a global company, we pride ourselves in our reach and ensuring your study targets are met. We can recruit all the candidates required by the study regardless of geographical barriers.
Longitudinal Studies
Understanding the long-term impact of your formulation of personal care products is only possible with our in vivo solution which requires human participants to test the products on themselves.

Why is a Human Approach Better when it Comes to Personal Care Product Testing?
At present, there are no regulations for microbiome-related formulas that brands and formulators can follow, however, it has been universally acknowledged that the in vivo method of conducting clinical studies is becoming critical to getting marketing claims through.
​
When regulations are introduced, which may be imminent, the in vitro system will find itself lacking, resulting in limited claims and certifications that do not hold their value. This is why, we at Sequential strive to offer an in vivo approach, knowing full well that we want our client's claims to be significantly backed by scientific and quantifiable data.

Analyze select bacteria within a lab setting
​
Narrow view of microbiome: Isolated from other bacteria
Cannot extract meaningful conclusions on how the product will interact with its place of application
Limited analysis: brief snapshot of how the product interacts with an isolated bacteria
Analyze all bacteria within its natural context
​
Broad view of microbiome: you can see interactions between bacteria
​
Can extract meaningful conclusions on how the product will interact with its place of application
​
Longitudinal analysis: evaluate the product over time and its impact on the microbiome
