Science
Mechanism of Action
Leveraging its comprehensive profile of organic acids, vitamins B and C, polyphenols, and amino acids derived from the fermentation process, this bioferment acts as a robust antioxidant, actively neutralizing free radicals and mitigating oxidative stress from environmental aggressors. It systematically promotes cellular regeneration and collagen synthesis, supporting skin's elasticity through anti-glycation properties which inhibit the degradation of collagen and elastin. Furthermore, it reinforces the skin barrier, reduces inflammation, and refines texture by balancing the natural microflora and providing gentle exfoliation, leading to a smoother, more even tone.

Key findings
- 01 Clinical trials at concentrations of 1.0-10.0% demonstrate significant free radical scavenging activity, restoration of skin vitality, enhanced moisture, and improved suppleness. Studies also report promotion of collagen synthesis and cell proliferation, alongside increased skin elasticity and resistance to external oxidative attack and UV damage, aiding in skin repair.
- 02 A manufacturer claim for use in toners at 60-70% suggests benefits in boosting radiance, smoothness, and skin thickness.
Transparency
Dusting Analysis
While some manufacturer claims suggest concentrations of 60-70% are utilized for specific effects such as boosting radiance, smoothness, and thickening skin in certain product categories like toners, a comprehensive array of clinical benefits, including potent antioxidant activity, collagen synthesis promotion, and skin repair, is demonstrably achieved within the 1.0-10.0% range.
The Formula
Formulation
Stability
The fermented product, Kombucha, maintains optimal stability and safety within a pH range of 2.5 to 4.2. This pH range is typically lower than the optimal growth pH for the constituent microorganisms.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) panel has deemed this ingredient safe for use in cosmetics. The Environmental Working Group (EWG) also assigns a low concern rating across various toxicity categories including cancer, allergies, and developmental toxicity. While generally well-tolerated, individuals with highly sensitive skin may experience mild, localized irritation; a preliminary patch test is recommended before widespread use.
