Science
Mechanism of Action
This ingredient operates through several key pathways to improve skin appearance and function. It actively combats free radicals, delivering significant antioxidant protection to cells. Mechanistically, it promotes fibroblast growth, essential for maintaining the skin's structural integrity, and inhibits the gene expression of TIMP-1 and Tropoelastin. Crucially, it suppresses the gene and protein expression of matrix metalloproteinases (MMP)-1, -2, and -3, enzymes responsible for collagen degradation, thereby preserving skin firmness and diminishing the appearance of fine lines. Its ability to inhibit Tyrosinase activity and Melanin synthesis also contributes to a more even skin tone and enhanced radiance. Furthermore, the Lactobacillus components generally stimulate the production of beta-defensins, serving as antimicrobial peptides, and exhibit anti-microbial and anti-inflammatory properties.

Stability
A pH of 5.0 was noted during the fermentation process for a similar Aspergillus-fermented extract, suggesting this pH range may be suitable for the microbial activity during its production.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel has concluded that Lactobacillus Ferment and related ingredients, including filtrates, are safe for use in cosmetic formulations. While unfermented sorghum extract has rarely been associated with allergic reactions or skin irritation in sensitive individuals, the fermented sorghum leaf/stem extract itself has been reported to have no adverse effects on the skin, indicating a favorable safety profile.
