Mechanism of Action
The mechanism involves a dual-action approach: Lactobacillus ferments release a spectrum of beneficial postbiotics including amino acids, peptides, organic acids (such as lactic acid), enzymes, and antioxidants. These compounds work synergistically to balance the skin's microflora, promote cell renewal, regulate pH, and offer humectant (hydrating) effects while calming irritation. Concurrently, Coriandrum Sativum contributes potent antioxidant activity, safeguarding human keratinocytes from oxidative damage by upregulating natural defense systems like glutathione and activating Nrf2 expression. Additionally, specific Lactobacillus postbiotics may contribute to skin brightening by inhibiting tyrosinase.

Stability
Coriandrum Sativum Seed Water components demonstrate general stability under recommended storage conditions, away from direct sunlight and extreme temperatures. Lactobacillus ferment ingredients, however, typically necessitate a comprehensive preservation strategy and precise pH control to maintain integrity and efficacy within a formulation.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Lactobacillus Ferment and Lactobacillus Ferment Filtrate, core components of this ingredient, are safe for use in cosmetics. The highest reported concentration for Lactobacillus Ferment in face and neck products is 5.6%. However, a reported risk of allergic reaction for sensitive skin exists, making a preliminary patch test advisable.
