Science
Mechanism of Action
This ingredient, along with related extracts, is abundant in bioactive compounds such as polyphenols, paeonol, and penta-O-galloyl-β-D-glucose (PGG). These compounds enable significant antioxidant activity by neutralizing free radicals and shielding skin from damaging oxygen species, thereby contributing to the reduction of dark spots, fine lines, and wrinkles. It exerts anti-inflammatory effects by mitigating skin inflammation, soothing irritation, and reducing redness, acting through pathways like AMPK/PI3K/Akt/Nrf2 to inhibit oxidative stress. Furthermore, it offers anti-aging benefits by enhancing skin tone and texture, diminishing hyperpigmentation, and ameliorating photoaging via the IRS1/PI3K/FOXO pathway. It also supports cell renewal, aids skin recovery from external aggressors, and contributes to skin brightening by reducing age spots and evening out tone, partly by inhibiting tyrosinase activity. Its moisturizing properties help maintain skin barrier function and reduce irritation.

Safety
Safety Profile
The CIR Expert Panel determined that available data are insufficient to conclude on the safety of Paeonia Suffruticosa Root Extract and related forms, including Paeonia Suffruticosa Root Water due to shared CAS numbers. Formulators are advised to ensure minimal impurities like heavy metals and pesticide residues. The Panel also cautioned that skin lightening is considered a drug effect, emphasizing that the ingredient should not cause depigmentation.
