Science
Mechanism of Action
The extract utilizes a high concentration of polyphenols, specifically catechins and procyanidins, to neutralize reactive oxygen species (ROS) and prevent oxidative damage. Furthermore, its natural sugar content (galactose and glucose) acts as a humectant to bind moisture to the skin, while organic phyto-acids provide a very gentle, non-irritating exfoliation that mimics the effects of mild AHAs to support cellular turnover.

Key findings
- 01 In vitro DPPH assays indicated a free radical scavenging capacity ranging from 55% to 90%, outperforming synthetic ascorbic acid in comparative potency at equivalent concentrations.
- 02 In vivo testing of the leaf oil components demonstrated a significant reduction in inflammatory markers, specifically reducing edema volume and inhibiting pro-inflammatory cytokines like IL-6.
- 03 Phyto-compound profiling identifies specific catechin structures that correlate with a reduction in visible wrinkle depth and improved skin elasticity.
Transparency
Dusting Analysis
Due to its premium source and marketing appeal as an 'Australian native,' this ingredient is frequently included in formulations at sub-therapeutic levels (under 0.5%) purely for label claims. For meaningful antioxidant and anti-inflammatory benefits, concentrations should ideally fall between 1% and 5%.
The Formula
Formulation
Stability
Maintains excellent stability in water and glycerin-based systems; however, the active catechins are prone to degradation if exposed to highly alkaline environments (pH > 7.0) or prolonged UV light and heat.
