Science
Mechanism of Action
The fermentation process meticulously breaks down complex biomolecules present in Camellia Sinensis, isolating and enhancing the bioavailability and efficacy of key beneficial components. This ingredient operates as a robust natural antioxidant, neutralizing free radicals responsible for premature skin aging. It delivers essential nutrients, including polysaccharides, peptides, vitamins, minerals, and amino acids, vital for skin nourishment and moisture retention. The ferment filtrate actively stimulates skin regeneration, fortifies the skin's protective barrier, and supports the production of collagen and elastin, leading to improved elasticity and a visible reduction in fine lines. Furthermore, it exhibits strong anti-inflammatory actions, reducing redness and irritation, while contributing to the balance of the skin's microflora, regulating pH, and offering protection against UV-induced damage, and can mildly exfoliate.

Key findings
- 01 Studies on the fermentation of Camellia Sinensis with probiotics, including Saccharomyces cerevisiae, indicate considerable enhancement in antioxidant, anti-inflammatory, tyrosinase inhibition, and collagenase inhibition activities.
- 02 Saccharomyces Ferment Filtrate, a core component, has demonstrated the ability to enhance skin regeneration, restore the protective barrier, boost skin elasticity and radiance, provide moisturization, soothe, combat free radicals, and reduce the appearance of fine lines. These effects have been observed in concentrations ranging from 0.1% to 5% in leave-on products and up to 10% in rinse-off formulations.
- 03 Topical application of Camellia Sinensis Leaf Extract, the other foundational component, at concentrations between 2% and 7% has shown improvements in skin hydration, barrier function, and rejuvenation. Specifically, a 6% glycolic extract significantly increased skin moisture (both immediate and long-term) and refined skin microrelief.

Dusting Analysis
As a complex bio-ferment known for its multi-functional benefits and enhanced bioavailability, this ingredient is not typically 'dusted' at sub-efficacious concentrations. Its value lies in the active, targeted delivery of beneficial compounds, making higher inclusion rates desirable for optimal results.
The Formula
Formulation
Stability
The potent catechins derived from Camellia Sinensis are inherently sensitive to light and oxygen, necessitating meticulous formulation strategies to preserve their biological activity. Furthermore, fermented bio-extracts may contain viable microorganisms, requiring stringent microbial elimination protocols such as filter separation or the incorporation of suitable sanitizers to ensure product safety and stability. The fermentation process itself naturally results in an acidic pH environment, typically shifting from a range of 4.87-5.08 to 3.26-3.50 over time.
Safety
Safety Profile
Saccharomyces Ferment Filtrate is widely regarded as safe for all skin types, with no significant reported side effects. Ingredients derived from Camellia Sinensis have been assessed by CIR as safe for cosmetic use when formulated to be non-sensitizing. The FDA also recognizes 'Tea Extract (Thea Sinensis L.)' as Generally Recognized As Safe (GRAS) and Saccharomyces cerevisiae derivatives as approved food additives. While the overall safety profile of fermented green tea extract is excellent, a patch test is recommended before extensive use, as rare allergic reactions may occur in individuals sensitive to plant extracts. Max concentration for Saccharomyces Ferment Filtrate is 5% in leave-on and 10% in rinse-off products, and for Camellia Sinensis leaf extract, it's 0.86% in leave-on and 1% in rinse-off products.
