Science
Mechanism of Action
This ingredient functions as a bioactive messenger system. It utilizes a complex matrix of catechins (specifically EGCG), amino acids, and plant-derived growth factors to neutralize reactive oxygen species (ROS) and inhibit matrix metalloproteinase-1 (MMP-1), the enzyme responsible for collagen degradation. Simultaneously, it signals dermal fibroblasts to accelerate Type I collagen synthesis and suppresses pro-inflammatory cytokines like IL-1 and IL-6.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Clinical evaluation demonstrated a significant reduction in UV-induced DNA damage and a preservation of epidermal Langerhans cells, essential for skin immunity.
- 02 A 4-week trial showed measurable improvements in global skin parameters including tactile texture, visual radiance, and tonal uniformity.
- 03 In-vitro studies confirm the inhibition of protein glycosylation (glycation), protecting skin elasticity from structural degradation.

Dusting Analysis
Due to its high cost and 'luxury' marketing appeal, many brands include this at symbolic levels (less than 0.1%). At Moumoujus, we consider levels below 0.1% to be 'label dusting' as they fall beneath the clinically validated threshold for DNA protection.
The Formula
Formulation
Stability
Highly thermolabile and photolabile. Must be processed in the cooling phase (under 40°C) and stored in opaque, airtight packaging to prevent the oxidation of catechin content.
Synergies
- L-Ascorbic Acid
- Hyaluronic Acid
- Niacinamide
Conflicts
- Strong oxidizing agents
- High temperature processing
- Alkaline environments (pH > 8.0)
Safety
Safety Profile
While the 2014 CIR report noted insufficient data for callus-specific extracts specifically, current toxicological profiles and widespread use in premium skincare indicate a high safety margin with no systemic toxicity reported.
