Science
Mechanism of Action
The extract operates through a multi-pathway approach: it neutralizes reactive oxygen species (ROS) via EGCG-rich catechins while simultaneously inhibiting collagenase enzymes to preserve the dermal matrix. On a cellular level, it triggers the synthesis of essential structural fibers—collagen, elastin, and proteoglycans—and optimizes keratinocyte differentiation to reinforce the skin's barrier integrity.

Key findings
- 01 Stimulation of extracellular matrix fibers (collagen and elastin) and balanced epidermal regeneration for increased skin density.
- 02 Significant reduction in sebum secretion and clinical improvement in acne-prone skin over an 8-week period.
- 03 Substantial increase in stratum corneum hydration and objective reduction in skin roughness within 30 days.

Dusting Analysis
While many formulas list Green Tea for marketing appeal at negligible levels, clinical efficacy for structural densification requires at least 0.5%. Formulations utilizing less than 0.1% are likely 'label dusting' and will not provide the documented cellular regenerative benefits.
The Formula
Formulation
Stability
Highly prone to oxidation and color shift; formulations must avoid temperatures exceeding 50°C and maintain an acidic to neutral pH. Requires protection from light and air.
