What it is
Bifida Ferment Lysate is produced by fermenting Bifidobacterium bacteria and then lysing the cells to release a mixture of metabolites, peptides, and other components. In skincare it is valued as a conditioning and comfort-oriented ingredient often featured in barrier-support and soothing formulas. In sunscreens it appears as a supporting active rather than as a UV filter.
