Science
Mechanism of Action
This extract functions primarily by conditioning the skin, imparting emollient effects that result in a smoother, softer texture. Its soothing action is attributed to key compounds such as flavonoids (e.g., kaempferol, quercetin, and isorhamnetin derivatives) and various caffeoylmalic and pyrrole acids. These constituents are associated with antioxidant and anti-inflammatory properties, contributing to the ingredient's ability to calm skin irritation and reduce discomfort.

Stability
The specific optimal pH range for the stability of Parietaria Officinalis Extract is not explicitly detailed. However, general guidance for plant extracts suggests that phenolic compounds, like those present in this extract, may exhibit enhanced stability at lower pH values (e.g., around 3.5). The extract is water-soluble and can be effectively formulated using common solvents such as water, ethyl alcohol, glycerine, or glycols.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed Parietaria Officinalis Extract. Independent assessments from EWG Skin Deep rate it as 'LOW' for common concerns including cancer, allergies & immunotoxicity, developmental & reproductive toxicity, and general use restrictions, indicating a favorable safety profile. INCI Beauty also reports 'No penalty' across all safety categories. While Parietaria pollen is a recognized allergen, cosmetic extracts are typically processed to minimize or eliminate such allergenic components, thereby reducing the risk of sensitization in skincare applications.
