Science
Mechanism of Action
This extract, often referred to as Petasites hybridus, exerts its anti-inflammatory effects primarily through active compounds such as petasins and sesquiterpene lactones, which act by inhibiting leukotriene synthesis. Its proposed role in skin tightening and firming is conceptually inspired by the leaf's dense, interconnected nerve network, which parallels the structural integrity desired within the skin.

Stability
For safe formulation, it is paramount to ensure that Petasites Vulgaris Leaf Extract is certified free of detectable levels of toxic pyrrolizidine alkaloids (PAs). No specific optimal pH range or general stability notes are available in the provided data.
Safety
Safety Profile
The primary safety concern associated with Petasites species is the potential presence of toxic pyrrolizidine alkaloids (PAs). It is critical that any extract intended for cosmetic use be certified as PA-free. The U.S. Food and Drug Administration (FDA) holds companies responsible for the safety of their cosmetic products. Topical application of PA-free essential oils from Petasites hybridus leaves has been shown to not elicit skin irritation in human subjects.
