Science
Mechanism of Action
It functions by stimulating the expression of COL17A1, a critical anchoring protein that maintains the structural integrity of the dermal-epidermal junction and promotes healthy stem cell competition. Simultaneously, it modulates the skin's inflammatory response by inhibiting pro-inflammatory cytokines like TNF-α and IL-6 while upregulating SIRT1 and FOXO1 genes to enhance cellular longevity and antioxidant defense.

Key findings
- 01 Demonstrated significant anti-melanogenesis activity (31.63%) and successfully upregulated anti-aging genes SIRT1 and FOXO1 without cytotoxicity.
- 02 Proven to induce COL17A1 expression, facilitating wound healing and maintaining epidermal thickness to prevent visible skin thinning.

Dusting Analysis
Because it shows gene-stimulating activity at very low concentrations (0.1 mg/mL), brands often include it at trace levels for marketing purposes; however, therapeutic anti-inflammatory and regenerative benefits typically require higher inclusion rates.
The Formula
Formulation
Stability
Highly sensitive to thermal degradation; should be formulated at temperatures below 45°C. The active flavonoid astilbin is prone to isomerization in alkaline environments.
