Science
Mechanism of Action
This extract modulates skin response by significantly downregulating inflammatory factors, including IL-1α, IL-6, and TRPV1, and reducing histamine release in mast cells by nearly 74%, thereby calming irritation and redness. It offers robust antioxidant protection against free radical damage and oxidative stress. Furthermore, it exhibits anti-aging properties by promoting collagen production, repairing UVB-induced DNA damage, inhibiting collagen-degrading matrix metalloproteinases (MMPs), and reducing senescent cells. The extract also contributes to a more even skin tone through melanin regulation and possesses moisturizing and skin barrier-supporting characteristics.

Stability
Specific optimal pH for overall extract stability is not detailed. While paeonol, a component of Paeonia suffruticosa, can have stability issues, this concern is specific to the isolated compound and not characteristic of the callus extract itself.
Safety
Safety Profile
The CIR Expert Panel found insufficient data for several Paeonia Suffruticosa extracts, including those from bark, root, and the general 'Paeonia Suffruticosa Extract', but 'Paeonia Suffruticosa Callus Extract' was not explicitly evaluated. However, independent studies suggest that peony callus extract is considered a safe and promising ingredient for cosmetic use. It is listed in the European Union's Cosmetic Ingredient Database (CosIng) with assigned functions, and its non-cytotoxic profile further supports its safety in concentrations up to 1%.
