What it is
Leuconostoc/rice ferment filtrate extract is produced by fermenting rice with Leuconostoc, a lactic acid bacterium, then filtering and extracting the resulting liquid. The ferment yields amino acids, peptides, and other metabolites that contribute conditioning and humectant properties to a formula. It is favored in skin care that emphasizes fermented, natural-derived ingredients.
Safety & warnings
This rice-based ferment filtrate extract is generally well tolerated in topical use. As with other ferment ingredients, sensitive individuals may occasionally experience mild irritation, so a patch test is reasonable for reactive skin. It is not considered comedogenic at typical use levels.
Origin & sourcing
Natural-derived; obtained by fermenting rice substrate with Leuconostoc bacteria and processing the filtered liquid into an extract.
