Science
Mechanism of Action
This extract functions through a multi-pathway approach: it inhibits Matrix Metalloproteinase-1 (MMP-1) to prevent collagen degradation and suppresses inflammatory signaling (NF-κB and IL-alpha) to reduce redness. Furthermore, its bioactive Astragaloside IV provides telomere protection while its complex polysaccharides reinforce the epidermal barrier and optimize moisture retention.

Key findings
- 01 At a 2% concentration, clinical trials observed a 20% increase in hydration and firmness within 14 days, alongside a 10-15% reduction in blemish markers after 42 days.
- 02 Topical application over 28 days demonstrated significant improvements in epidermal brightness and a visible reduction in wrinkle depth.
- 03 Research into saponin-rich blends containing Astragalus showed an 8.7% increase in collagen levels and a 19.8% improvement in overall skin texture.
Transparency
Dusting Analysis
Astragalus is frequently used in 'label-claim' amounts (below 0.5%) for its traditional reputation; however, precision formulation requires at least 2% to achieve the structural and hydrating benefits seen in clinical data.
The Formula
Formulation
Stability
The extract exhibits high stability in aqueous solutions, particularly between pH 5.0 and 8.0. To preserve its delicate bioactive polysaccharides, it should be integrated during the cooling phase of production (below 40°C).
