Science
Mechanism of Action
This extract operates through several pathways to enhance skin health. It significantly reduces inflammation by inhibiting the formation of pro-inflammatory mediators like IL-6 and PGE2, and by deactivating TNF-α induced NF-κB signaling within keratinocytes. Its vasoconstrictive properties, partly achieved by scavenging nitric oxide (NO) and inhibiting endothelial NO synthase (eNOS), can lead to a visible blanching effect. Potentilla Erecta Extract reinforces the skin's structural integrity by stimulating collagen VII synthesis, crucial for dermal-epidermal cohesion, which in turn diminishes wrinkles and strengthens the skin. Furthermore, its tannin content contributes to astringent effects, minimizing pore appearance and controlling excess oil, alongside mild antiseptic and antioxidant actions. It also supports wound healing and promotes a more even skin tone and texture.

Key findings
- 01 Clinical research indicates that concentrations between 2-5% are recommended for optimal results in formulations targeting skin barrier reinforcement, intense hydration, antioxidant protection, anti-inflammatory action, and a reduction in aging indicators.
- 02 Cell culture studies have demonstrated efficacy at 0.0001%-1%, with 0.01-0.5% being preferable, for stimulating collagen VII synthesis in human keratinocytes and fibroblasts, which improves dermal-epidermal cohesion.
- 03 Unspecified concentrations of the extract have exhibited significant anti-inflammatory capabilities, reducing inflammatory markers (IL-6, PGE2) and inhibiting NF-κB activation, as well as vasoconstrictive effects, supporting its use in inflammatory skin conditions.
- 04 Studies also point to its potential for improved and accelerated diabetic wound healing and altered oxidative events.
- 05 Topical application of an extract-containing gel showed anti-inflammatory effects by reducing rat paw edema and was considered safe with no irritation in rats, affirming its safety for external use.

Dusting Analysis
Potentilla Erecta Extract demonstrates effectiveness for specific mechanisms, such as collagen VII stimulation, at concentrations as low as 0.0001%. However, achieving optimal, broad-spectrum benefits, including robust barrier strengthening, deep hydration, anti-inflammatory, and anti-aging effects, typically requires formulations containing 2-5%. Products claiming comprehensive efficacy with concentrations below 2% may be underdosing for optimal results, and usage below 0.0001% is highly indicative of cosmetic dusting, offering negligible functional benefit.

Safety
Safety Profile
Acute toxicity studies in rats and mice, involving high intragastric and intraperitoneal doses, indicated no mortality or adverse effects, suggesting a favorable acute safety profile for humans. Topical application of an extract-containing gel caused no irritation in rats, supporting its safety for dermal use. However, no specific safety assessments by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) are currently available.
