Science
Mechanism of Action
The fermentation process, mediated by Saccharomyces, fundamentally transforms and optimizes the bioactive compounds from Camellia Sinensis, enhancing their stability and skin absorption. This ingredient provides a rich source of essential nutrients and potent antioxidants, which collectively work to reduce inflammation, stimulate collagen production, and visibly improve skin elasticity, texture, and the appearance of fine lines. Concurrently, it fortifies the skin's natural barrier and deeply moisturizes. Fermentation byproducts like lactic acid contribute to pH regulation and gentle exfoliation, while bacteriocins and hydrogen peroxide offer antimicrobial and anti-inflammatory support, fostering a balanced and healthy skin microbiome.

Key findings
- 01 Saccharomyces Ferment Filtrate has been shown to reduce inflammation, promote collagen production, improve skin elasticity and texture, and decrease the appearance of fine lines and wrinkles. It also enhances the skin's natural barrier function and moisturizes.
- 02 Green tea extract (Camellia sinensis) demonstrated significant anti-sebum efficacy in facial toners during a randomized, placebo-controlled study.
- 03 Glycolic extracts of Camellia sinensis leaves, when applied topically, notably increased both immediate and long-term skin moisture, and refined skin microrelief, leading to a reduction in roughness.
- 04 Acute topical application of Camellia sinensis leaf extract improved skin hydration, barrier function, and rejuvenation. Long-term use was linked to improved facial skin health and a reduced skin age perception.
- 05 Bio-extracts of Camellia sinensis var. assamica, fermented with probiotics including Saccharomyces cerevisiae, exhibited considerable antioxidant, lipid peroxidation inhibition, nitric oxide inhibition, tyrosinase inhibition (MMP-1 and MMP-2), collagenase inhibition, and antimicrobial activity.

Dusting Analysis
Extensive research supporting the benefits of both Saccharomyces ferment and Camellia sinensis, along with studies on their fermented combination, demonstrates a clear, active efficacy profile. This indicates the ingredient's genuine functionality rather than a 'dusting' application.
The Formula
Formulation
Stability
The fermentation process is critical for enhancing the stability of catechins and other active compounds from Camellia Sinensis, which are otherwise highly sensitive to light and oxygen. Fermented Miang tea bio-extracts show improved stability within an acidic pH range, often reducing to pH 3.26-3.50 during fermentation.
Safety
Safety Profile
The CIR Expert Panel deemed Camellia Sinensis leaf extract safe for use up to 0.86% in leave-on products and 1% in rinse-offs, provided it is formulated to be non-sensitizing. Saccharomyces Ferment Filtrate itself is generally considered safe at 0.1%-5% in leave-ons. While fermented green tea extract typically has an excellent safety profile, rare instances of allergic reactions, irritation, redness, or itching may occur, making patch testing advisable for sensitive individuals. The stated maximum concentration refers to the Camellia Sinensis component in leave-on applications for this combined ingredient.
