Science
Mechanism of Action
Through a sophisticated fermentation process, this ingredient converts active ginsenosides into more potent and skin-accessible forms, thereby enhancing their overall efficacy. It supports a healthy cutaneous microflora balance, which is vital for maintaining the skin's protective barrier and facilitating natural regeneration. Furthermore, its adaptogenic properties aid the skin in resisting environmental stressors and pollution. This complex delivers comprehensive benefits, including potent antioxidant action against free radicals, profound hydration, nourishment, and support for cell regeneration, leading to improved skin resilience and a more radiant appearance. Specific lactobacillus ferments also demonstrate the ability to inhibit tyrosinase activity, potentially contributing to a more even skin tone.

Key findings
- 01 Fermented red ginseng extract (FRGE) showed enhanced antioxidant activity, ranging from 44.05% to 61.95%, at concentrations between 0.25 to 4 mg/mL in vitro, surpassing the effects of unfermented red ginseng.
- 02 A 10% concentration of fermented red ginseng was classified as practically non-irritating (P.I.I. score of 0) in primary skin irritation tests. It significantly reduced sensitization risk to 20% (with a mean irritation score of 0.2) compared to 100% sensitization and a 1.4 irritation score observed with unfermented ginseng.
- 03 Topical application of a Saccharomyces and Lactobacillus ferment complex effectively alleviated symptoms such as itching, prickling, tightness, dandruff, and burning in a study involving 30 female volunteers with sensitive scalp syndrome.

Stability
This ingredient demonstrates stability and activity within an acidic environment, a characteristic supported by a pH decrease from 6.45 to 3.64 during the fermentation process due to lactic acid production.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of Lactobacillus Ferment ingredients, including similar ferments, for cosmetic applications. Notably, the fermentation process significantly improves the safety profile of red ginseng, reducing its irritancy and allergenic potential. While some Lactobacillus ferments may exhibit skin-lightening effects through tyrosinase inhibition, formulators are advised to ensure usage does not lead to unintended depigmentation. Although generally well-tolerated, individuals with sensitivities to probiotics or ginseng are advised to perform a patch test. No specific maximum concentration or pregnancy safety data for the full complex was found in the provided research.
