Science
Mechanism of Action
This ingredient operates via a dual-action pathway: it neutralizes reactive oxygen species (ROS) using a potent complex of L-ascorbic acid, epicatechin, and gallic acid, while downregulating pro-inflammatory cytokines such as TNF-α and IL-6 to soothe dermal irritation. Its high polysaccharide and sugar content (pectin, glucose, and fructose) creates a hydrating film that binds water to the stratum corneum.

Clinical Evidence
Medium confidence0.5%
Key findings
- 01 In vivo murine models demonstrated a 78% reduction in induced ear edema, highlighting significant anti-inflammatory suppression of leukocyte migration.
- 02 Enzymatic optimization studies indicate that a 0.15% concentration is the threshold for maximizing antioxidant and phenolic compound bioavailability.

Dusting Analysis
Due to its exotic appeal, it is often included at negligible levels (<0.05%) for marketing purposes. To provide physiological benefits, particularly antioxidant support, it should be present at 0.15% or higher.
The Formula
Formulation
Stability
Highly sensitive to photo-oxidation and thermal degradation; requires opaque, airtight packaging. Depectinization is often required to maintain formula clarity.
