Paeonia Suffruticosa Extract

Paeonia suffruticosa (tree peony) extract is a botanical antioxidant/soothing agent typically used at low percentages, but botanical extracts contain multiple bioactive compounds and trace constituents that can trigger stinging or dermatitis in reactive or eczematous skin. Human patch-test and post-market data for peony extracts generally suggest low overall irritancy, yet unpredictable individual reactions (including delayed hypersensitivity) are plausible, especially in compromised skin barriers and when layered with other actives. Given the variability of extract composition and the higher risk profile of botanicals in highly sensitive populations, a mild irritancy score is the safer clinically aligned assessment. Safety Notes: In mass-market leave-on skincare (toners/lotions/creams) Paeonia suffruticosa (tree peony) extract is commonly used as a minor botanical antioxidant/brightening support, often dosed at ~0.001–0.1% active extract (especially when part of multi-extract blends or when supplied in glycerin/butylene glycol). Higher-strength consumer serums and “single-hero botanical” calming/brightening products can reach ~1–5% of the supplier extract solution, with practical upper limits driven by odor/color, solubility, and potential sensitivity rather than regulatory caps; rinse-off products typically sit toward the low end due to brief contact time.
