Microbiota analysis offers important new indicators of the safety and efficacy of your cosmetic and personal care products for the skin and scalp.

The skin is the largest human organ. Skin flora or microbiota contribute to the equilibrium of the skin barrier and are an important bioindicator of human health. The microbiome of healthy human skin contains around 1,000 bacterial species and over two million genes. The equilibrium of skin and scalp flora contributes to overall health, and an imbalance contributes to conditions such as dermatitis, eczema, psoriasis, acne and dandruff.

Mérieux NutriSciences conducts innovative research into the human microbiome in the areas of nutrition, health and cosmetics. Skin microbiota analysis offers promising opportunities for applied research in cosmetics and dermatology:

  • Prediction of skin disorders (characterization or microbiota health indicators)
  • Prevention and treatment of skin disorders (modulation of skin flora)
  • Personalized product development (based on skin flora characteristics)

We offer the following microbiota analysis services and studies in support of your new product or research project:

  • Clinical study design, recruitment and statistical analysis
    • Exploratory studies for characterization of skin microbiota based on ethnicity, age, sex, body site, healthy or diseased skin or scalp
    • Comparative studies for tolerance testing: skin microbiota equilibrium including composition, diversity, richness and homeostasis
    • Modulation of microbiome studies to determine beneficial effects of probiotics, and skin and scalp products
  • Biological analysis such as oxidative stress, and immune and inflammatory markers
  • Skin and gut microbiota characterization including sampling, logistics and processing, bioinformatics and statistical analysis
  • Reports and scientific communications
