Science
Mechanism of Action
This complex acts through multiple pathways to enhance skin vitality. Polygonatum sibiricum rhizome inherently provides robust antioxidant defense, helps to regulate immune responses, and demonstrably reduces inflammatory markers such as iNOS and TNF-α. Its rich polysaccharides further support antioxidant functions and promote skin barrier integrity. The fermentation process, driven by Lactobacillus and Saccharomyces, significantly boosts the bioavailability of these active compounds while generating new beneficial metabolites, including organic acids. Lactobacillus ferments are also recognized for their ability to support DNA repair mechanisms, shield skin from environmental damage, and exert antimicrobial actions, which can help balance the skin's microflora, potentially addressing concerns like acne and rosacea.

The Formula
Formulation
Stability
This ferment extract maintains stability and efficacy within acidic to near-neutral pH conditions, typically above pH 4.00, aligning with common fermentation and product shelf-life requirements. It is formulated exclusively for topical skincare applications and is not intended for use as a fragrance or flavor component.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Lactobacillus Ferment and related derivatives safe for cosmetic use, with a reported maximum concentration of 5.6% in face and neck products. While this assessment specifically covers the Lactobacillus ferment aspect, a dedicated safety review for the full LACTOBACILLUS/SACCHAROMYCES/POLYGONATUM SIBIRICUM RHIZOME FERMENT EXTRACT complex by CIR or SCCS has not been individually identified. However, Polygonatum sibiricum itself has a documented history of safe use in medicinal and edible applications with minimal reported adverse effects.
