Science
Mechanism of Action
This extract operates through a triple-action pathway: it inhibits tyrosinase enzymes to disrupt melanin production, neutralizes reactive oxygen species (ROS) via potent antioxidant activity, and protects the dermal matrix by suppressing collagenase and elastase—the enzymes responsible for breaking down skin elasticity.

Dusting Analysis
While effective at 1.0% for brightening, many mass-market formulations include it at trace levels (<0.1%) merely for botanical claims. To achieve measurable anti-glycation and brightening results, concentrations between 1% and 5% are recommended.
The Formula
Formulation
Stability
Highly thermolabile due to Vitamin C and polyphenol density; must be incorporated during the cooling phase below 40°C. Requires opaque, air-restrictive packaging to prevent oxidation.
Synergies
- Ascorbic Acid
- Niacinamide
- Hyaluronic Acid
Conflicts
- Strong oxidizing agents
- High pH formulations (>7.0)
Safety
Safety Profile
While the specific flower extract is pending a formal CIR review, it is closely related to food-grade species (C. sinensis) and is generally recognized as safe for topical application up to 5%.
