The human microbiome plays a crucial role in immune regulation and skin barrier function. Clinical studies have shown that dysbiosis—an imbalance in microbial communities—correlates with increased allergy incidence, with up to 20-30% of patients showing altered microbiota profiles. Similarly, compromised skin barrier function is associated with reduced microbial diversity and altered inflammatory responses.

The challenge lies in identifying and maintaining specific bacterial populations that can modulate immune responses while preserving the delicate balance of the skin's microenvironment.

This page brings together solutions from recent research—including targeted bacterial strain selections (Akkermansia, Faecalibacterium, and Lactobacillus combinations), biofilm management strategies, and microbiome-based approaches for inflammatory skin conditions. These and other approaches focus on developing stable formulations that maintain bacterial viability while delivering consistent therapeutic benefits.
