Science
Mechanism of Action
LACTOBACILLUS/LANOLIN FERMENT EXTRACT operates through a dual-action mechanism derived from its components. The Lactobacillus ferment component exerts probiotic effects by naturally acidifying the skin's microenvironment and generating antimicrobial peptides, known as bacteriocins, which inhibit undesirable microbial growth. It further supports the skin's inherent barrier function, offers antioxidant and hydrating benefits, and contributes to anti-inflammatory responses and DNA repair. Concurrently, the Lanolin component acts as a potent emollient and occlusive agent, forming a protective lipid barrier on the skin's surface. This barrier effectively minimizes trans-epidermal water loss (TEWL), ensuring sustained hydration and promoting skin softness and suppleness.

Stability
For optimal stability, this water-soluble extract should be incorporated into water-based formulations or the aqueous phase of emulsions. Integration is best performed during the cooling phase, at temperatures maintained below 70°C (158°F), and ideally before the addition of thickening agents. Comprehensive challenge testing of the final formulation is highly recommended to validate preservation efficacy.
Safety
Safety Profile
While there is no specific Cosmetic Ingredient Review (CIR) assessment for the combined LACTOBACILLUS/LANOLIN FERMENT EXTRACT, its individual components have been evaluated. The CIR Expert Panel considers Lactobacillus Ferment and related derivatives safe for cosmetic use (observed up to 5.6% in face and neck products). Lanolin and its derivatives are also deemed safe for topical application, with maximum concentrations of 40% in leave-on and 10% in rinse-off products, and 0.2% for children's products.
