Science
Mechanism of Action
Potentilla chinensis extract operates through several distinct pathways to enhance skin health. As an anti-inflammatory agent, it effectively inhibits nitric oxide (NO) production, down-regulates iNOS expression, and reduces cyclooxygenase-2 (COX-2) expression. Its antioxidant capabilities are robust, involving the scavenging of various free radicals (DPPH, superoxide anions, nitric oxide, ABTS) and the inhibition of reactive oxygen species (ROS) generation. For anti-aging, the extract—specifically through compounds like potentilloside A—decreases Matrix Metalloproteinase-1 (MMP-1) secretion to limit collagen degradation and stimulates COL1A1 expression for enhanced collagen synthesis. Potentilloside A also modulates cellular signaling by inhibiting the phosphorylation of ERK, JNK, and c-Jun, critical pathways in ECM-degrading enzyme upregulation. Furthermore, the flower extract exhibits a unique botulinum neurotoxin-like effect, interfering with SNARE complex formation to inhibit neurotransmitter release, thereby reducing neuroexocytosis and muscle contraction. Potential benefits observed in related Potentilla species also suggest roles in moisturizing, anti-melanogenesis, and wound healing, possibly via hyaluronic acid synthesis and barrier function improvement.

Key findings
- 01 Inhibited neurotransmitter release from neuronal PC12 cells by approximately 90% and reduced muscle contraction by 70% within 60 minutes, indicative of a botulinum neurotoxin-like function through interference with SNARE complex formation.
- 02 Significantly inhibited TNF-α-induced Reactive Oxygen Species (ROS) generation in human dermal fibroblasts, highlighting its antioxidant potential.
- 03 Potentilloside A, an isolated compound, dramatically decreased Matrix Metalloproteinase-1 (MMP-1) secretion by 1.96 ± 0.14-fold and 0.56 ± 0.05-fold, respectively, in TNF-α stimulated normal human dermal fibroblasts, suggesting a strong anti-aging effect by inhibiting collagen degradation.

Stability
No specific optimal pH range for stability has been identified. However, as a water-soluble plant extract, it is typically incorporated into the aqueous phase of formulations.
Safety
Safety Profile
In vitro studies on normal human dermal fibroblasts (NHDFs) showed no remarkable cytotoxicity for Potentilla chinensis extract and its isolates within a concentration range of 1–100 μM. INCI Beauty indicates 'No penalty' in all categories for this ingredient, generally suggesting a favorable safety profile.
