What it is
Lactobacillus/Grape Juice Ferment Filtrate is made by fermenting grape juice with Lactobacillus bacteria and filtering the resulting broth. Grapes contribute polyphenols, and the fermented filtrate is used as a conditioning, water-binding ingredient with plant-derived antioxidant constituents. It typically appears in the water phase of a formula at modest levels.
Safety & warnings
Ferment filtrates of this type are generally well tolerated at cosmetic use levels. As with other fermentation-derived botanicals, occasional contact sensitivity is possible in predisposed individuals. The filtrate is cell-free and does not contain live cultures.
Origin & sourcing
Natural-derived via fermentation; grape juice is fermented with Lactobacillus bacteria and the liquid is filtered to produce the cell-free ingredient.
Questions everyone asks
Does this contain alcohol?
It is a filtered ferment intended as a conditioning ingredient; any byproducts of fermentation are part of the processed filtrate rather than added alcohol, and it is used at low cosmetic levels.
What does fermented grape juice do for skin?
It acts as a skin-conditioning, water-binding, and antioxidant botanical additive within the formula and does not provide sun protection.
