Science & Benefits

Lactobacillus/Milk Ferment Filtrate is a probiotic-rich active containing natural Lactic Acid, proteins, and vitamins. It works to lower the skin's surface pH, creating an inhospitable environment for pathogenic C. acnes. As a humectant, it provides NMF-identical minerals and moisture. It is completely non-comedogenic. It is a strategic choice for rebalancing the skin's acid mantle after cleansing, providing hydration and microbiome support in one weightless, water-soluble vehicle.
