Apium Graveolens Extract

Apium graveolens (celery) extract is a botanical additive typically used at low concentrations for antioxidant/soothing claims, but celery contains furocoumarins and other sensitizing constituents that have documented associations with allergic contact dermatitis and can contribute to photosensitivity in susceptible individuals. In sensitive-skin and eczema populations, botanical extracts are a common trigger category in patch testing, and risk rises with leave-on use and cumulative exposure alongside other irritants. Given the non-essential benefit and credible sensitization/irritation potential despite low typical use levels, a moderate irritancy score is the safer clinically aligned assessment. Safety Notes: In mass-market leave-on skincare, Apium graveolens (celery) extract is commonly used as a minor botanical supportive ingredient, often at trace-to-low levels (~0.0005–0.1%) when supplied as a diluted extract in a blend or as part of a preservative/soothing complex. Mid-range “natural” serums, toners, and moisturizers typically place it around 0.1–1% as a named botanical. Higher-strength consumer-available products (botanical concentrates, booster serums, and some wash-off masks) can reach ~2–5% when the supplier material is a standardized/glycerin or glycol extract and sensorial/irritation limits are managed; above this is uncommon OTC due to odor/color, stability, and potential sensitization risk typical of aromatic plant extracts.
