Science
Mechanism of Action
This ingredient operates by leveraging Pichia yeast to ferment Panax ginseng roots, a process that significantly increases the skin's ability to absorb the active compounds. The resulting filtrate is enriched with optimized nutrients and potent antioxidants, which collectively strengthen the skin's protective barrier, stimulate cellular renewal, and contribute to a balanced skin microbiome. Functioning as a comprehensive skin conditioning agent, it improves the skin's resilience to external stressors and maintains optimal hydration levels.

Stability
This water-soluble ingredient integrates readily into various aqueous cosmetic formulations. While a precise pH stability range for the filtrate itself is not specified, optimal stability for key ginsenosides (Rg1, Rb1) within red ginseng extract products is noted at approximately pH 6.0, which also aligns with the optimal pH for Pichia pastoris fermentation processes.
Safety
Safety Profile
Generally regarded as safe for cosmetic use and well-tolerated across most skin types, this ingredient is described as non-irritating and non-sensitizing. However, the Cosmetic Ingredient Review (CIR) Panel has indicated 'insufficient data' for a comprehensive safety assessment under intended conditions of use for this specific ingredient. While studies on other fermented ginseng types (e.g., Lactobacillus brevis) show reduced sensitization compared to unfermented versions, this specific Pichia fermentation has not been directly assessed in similar detailed studies. Individuals with known allergies to plants or exceptionally sensitive skin should proceed with caution.
