Science
Mechanism of Action
This extract operates through a multi-pathway approach: it suppresses pro-inflammatory mediators like IL-6 and PGE2 to calm systemic irritation, boosts Ki-67 expression to accelerate cellular renewal, and stimulates the production of essential structural proteins including collagen, elastin, and glycosaminoglycans (GAGs).
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 A 28-day clinical trial involving 20 participants (ages 40–60) utilized a 0.5% concentration, resulting in a statistically significant reduction in wrinkle depth and improved skin micro-topography.
- 02 In vitro analysis at 10% concentration confirmed the extract supports fibroblast proliferation and enhances wound-healing mechanisms without cytotoxicity.
Transparency
Dusting Analysis
Because this is a specialized callus (stem cell) culture, it is significantly more expensive than standard Calendula flower extract. Products claiming regenerative benefits while listing it at concentrations below 0.5% may not be providing the levels required to match clinical anti-wrinkle benchmarks.
The Formula
Formulation
Stability
Highly stable in various emulsion types (O/W and W/O) but sensitive to light and oxidation; formulations should be stored in opaque, cool environments to preserve carotenoid and flavonoid integrity.
Synergies
- Hyaluronic Acid
- Peptides
- Vitamin E
Conflicts
- Strong oxidizing agents
- Extreme pH environments
Safety
