Prunus Persica Leaf Extract

Prunus persica (peach) leaf extract is a botanical soothing/antioxidant additive typically used at low concentrations, but peach-derived plant materials can contain sensitizing constituents and show occasional positive reactions in patch testing, especially in atopic (eczema-prone) individuals. Because botanicals have variable composition and can trigger delayed hypersensitivity or stinging on compromised barriers despite being marketed as “gentle,” I rate it as mild with a meaningful but not frequent irritation risk in sensitive skin. Safety Notes: In commercial skincare, Prunus Persica (Peach) Leaf Extract is most often used as a low-level botanical supporting ingredient in leave-on lotions/serums and rinse-off cleansers, where it commonly appears in the ~0.001–0.5% range and can be present at trace levels (~0.0001%) when part of a blended preservative/soothing botanical complex. High-strength consumer-available products marketed as botanical/“single-extract” boosters or concentrate ampoules can push total extract (as supplied) into the ~1–5% range, with practical limits driven by odor/color, solubility, and batch-to-batch variability rather than specific regulatory caps.
