Skin microbiota plays a key role in maintening skin balance and health. How can you ensure your ingredients respect it?
For 20 years, GLYcoDiag has been providing high-level microbiology expertise to the cosmetics industry.
For over a decade, we have supported our clients in objectively assessing the impact of ingredients and formulations on the microbiota.
- Advanced in vitro co-culture models
We develop biologically relevant co-culture models based on selected wild-type strains, grown under strictly controlled and reproducible conditions.
Our models cover major skin microbiota ecosystems:
• Dry, wet and sebaceous skin
• Scalp
• Face
• Oral
• Intimate
They enable the simulation of both eubiosis and dysbiosis, providing a realistic framework for evaluating ingredient behavior.
- Reliable. Reproducible. Discriminating.
Our validated methodologies generate robust data that clearly differentiate microbiota-neutral, modulatory or antimicrobial effects — supporting confident decision-making for R&D, regulatory and marketing teams.
Our scientific leadership has been recognized through peer-reviewed publications.
Our co-culture model to identifiy cosmetic ingredients that respect the skin microbiota developped in collabiration with SEPPIC is published (https://library.scconline.org/v075n06/38) and patented (FR3160187).
- From microbiota-friendly / neutral / respect positioning to certification-oriented studies, we design tailored protocols aligned with current scientific and regulatory expectations.
Independent expertise. Strategic partnership. Rigorously scientific.
