Science
Mechanism of Action
The fermentation process of Chondrus ocellatus by Lactobacillus yields a rich filtrate abundant in beneficial postbiotic compounds including amino acids, peptides, organic acids (such as lactic acid), enzymes, and antioxidants. These components collectively enhance skin hydration through potent humectant action, fortify the skin barrier, and foster a stable skin microbiome, which in turn helps to calm irritation. It also provides robust antioxidant protection against environmental stressors, balances the skin's pH, promotes gentle exfoliation and cell renewal, and may contribute to skin brightening by inhibiting tyrosinase activity.

Stability
While a specific optimal pH range for the stability of this filtrate in formulations is not explicitly defined, the fermentation process typically occurs within a slightly acidic range of pH 4-5. Formulators may need to consider pH control and the use of co-preservatives for optimal stability and efficacy, especially given its aqueous solubility.
