Science
Mechanism of Action
This ingredient operates through a triple-action pathway: it neutralizes free radicals via flavonoid-rich antioxidant activity, prevents the enzymatic breakdown of collagen and elastin by inhibiting MMP-2 and elastase, and utilizes phyto-compounds to modulate melanogenesis for improved skin clarity.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 In vitro trials confirmed that concentrations as low as 0.1% provide antioxidant protection comparable to 0.1% Catechin.
- 02 Studies at 0.5% concentration demonstrated significant inhibition of elastase, protecting the skin's structural proteins from degradation.
- 03 Clinical assays at 0.25% to 0.5% showed effective suppression of melanin production in B16 melanoma cells.

Dusting Analysis
Due to its premium 'Sakura' branding, many products include this at symbolic levels (below 0.05%). At Moumoujus, we recognize that biological activity for radical scavenging and melanin inhibition requires at least 0.1% to 0.25% for measurable cellular benefits.
The Formula
Formulation
Stability
Highly stable in aqueous and glycolic solutions; however, the powder form is sensitive to oxidation and should be protected from light and moisture. Excessive heat during processing may degrade delicate floral polyphenols.
Synergies
- Vitamin C
- Niacinamide
- Hyaluronic Acid
Conflicts
- Strong oxidizing agents
- Highly alkaline formulations (pH > 8.0)
Safety
Safety Profile
Human patch testing on the 0.8% extract solution confirmed zero irritation, making it suitable for delicate skin types.
