BIFIDOBACTERIUM.

Valuable / SKIN PROTECTING

A sophisticated probiotic-derived lysate engineered to fortify the skin's microbiome and accelerate cellular recovery. This bio-fermented active transitions beyond surface hydration to modulate nerve reactivity and reinforce the physical skin barrier at a structural level.

Science

Mechanism of Action

Bifidobacterium Ferment Lysate functions through a multi-pathway approach: it stimulates the production of tight-junction proteins to seal the epidermal barrier and enhances keratinocyte differentiation. It acts as a biological desensitizer by inhibiting the release of CGRP (calcitonin gene-related peptide) from sensory neurons, while providing enzymatic support for DNA repair and neutralizing UVA-induced oxidative stress.

Key findings

  1. 01 A 29-day clinical trial confirmed that a 10% concentration significantly improved barrier function and reduced skin sensitivity in stinging tests.
  2. 02 In vitro models demonstrate that concentrations between 2-10% effectively inhibit UVA-induced oxidative damage and intracellular ROS levels.
  3. 03 Nerve cell culture studies indicate that 1% concentration is sufficient to inhibit capsaicin-induced CGRP release, reducing sensory reactivity.

While many formulas include this ingredient for 'probiotic' marketing claims, concentrations below 1% may fail to provide the desensitizing and barrier-repair benefits observed in clinical benchmarks. Effective therapeutic formulations typically range from 5% to 10%.
