Sequential

The Biome Mask has been created with the goal of maintaining the microbiome while targeting concerns such as skin dehydration and sensitivity.

Extend your clinical trials and studies with specialist human biomarker, microbiome and multi-omics capabilities. We work alongside your existing protocol.

Measure the body's biological response to your product or treatment. Human biomarker panels show changes in the host, not only in the microbes on it.

Non-invasive sampling designed around real product use. Validated methods that collect human and microbial samples remotely or in the clinic.

The oral cavity supports complex microbial communities that play a crucial role in both oral and systemic health. When this balance is disrupted, it can lead to conditions such as gingivitis and periodontitis.

Proteomics is the large-scale study of proteins, how they are expressed, modified and interact with the body. In skincare, proteomics is emerging as a powerful tool to understand how products influence skin function at a molecular level.

Case studies, white papers and articles. Practical reading on clinical study findings, novel ingredients and actives, biomarkers and multi-omics.

Taking a microbiome sample for the purpose of gene expression.
