Science
Mechanism of Action
This extract operates through a triple-action pathway: it inhibits tyrosinase activity to regulate melanin production, stimulates dermal fibroblasts to accelerate collagen and hyaluronic acid synthesis, and suppresses matrix metalloproteinases (MMP-2) and collagenase to prevent the enzymatic degradation of the skin's structural framework.

Clinical Evidence
High confidence2.5%
Key findings
- 01 In-vitro analysis at 200 μg/mL demonstrated significant upregulation of collagen and HA while providing potent anti-tyrosinase effects (Jing-Zhong et al., 2016).
- 02 A 3-month clinical trial using a 5% concentration showed measurable improvements in skin barrier function, hydration levels, and a visible reduction in wrinkle depth (MDPI, 2012).
- 03 Recent 2024 data highlights its efficacy in acne management due to targeted antimicrobial and anti-inflammatory properties at pH 5.5.
Transparency
Dusting Analysis
While bioactive effects are observed as low as 0.02% in vitro, clinical improvements in texture and barrier function typically require concentrations between 1% and 5%. Formulae listing this ingredient near the bottom of the INCI list often use it for label claims rather than physiological impact.
The Formula
Formulation
Stability
The extract remains thermally stable up to 40°C; however, its phenolic antioxidants are sensitive to prolonged high heat and alkaline environments.
Synergies
- Vitamin C (L-Ascorbic Acid)
