Science
Mechanism of Action
Milk Ferment influences the skin's ecosystem by modulating the skin microbiome. It releases bioactive peptides and stabilizes sebum production. The organic acids, such as lactic and propionic acids, produced during fermentation, create an acidic environment that can inhibit the growth of skin pathogens. Furthermore, lysates of probiotic bacteria, often present in ferments, are known to improve skin barrier function.

Stability
Fermented milks are inherently acidic, typically ranging from pH 3.16 to 4.92, often standardized between 4.0 and 4.5. For optimal stability and to prevent off-flavors in lactic acid fermented emulsions containing milk solids and water, a pH range of 3.5 to 5.3 is preferred, with a more precise range of 4.0 to 4.7 being even more beneficial. This acidic condition also aids in product preservation by inhibiting spoilage and bacterial growth.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Lactobacillus Ferment ingredients (including Lactobacillus Ferment, Lactobacillus Ferment Filtrate, Lactobacillus Ferment Lysate, and Lactobacillus Ferment Lysate Filtrate) safe for cosmetic use. Separately, CIR also found bovine milk proteins and their derivatives safe, reporting no relevant ocular or dermal irritation or sensitization in animal or human studies. The U.S. FDA recognizes bovine milk, proteins, and derivatives as Generally Recognized As Safe (GRAS).
