Centella Asiatica Leaf Extract

Centella asiatica leaf extract is primarily a soothing/anti-inflammatory botanical used in leave-on products typically around ~0.1–5% (with variability depending on standardization), and it is generally well-tolerated in sensitive and eczema-prone skin. However, as a complex plant extract it can contain multiple constituents with batch-to-batch variation, and rare irritation or allergic contact dermatitis has been reported in patch testing and case reports, so it is not truly inert. Given its overall low incidence of reactions but nonzero sensitization potential typical of botanicals, a very gentle score is appropriate. Safety Notes: In mass-market leave-on products (lotions, cleansers, toners) Centella asiatica leaf extract is frequently used at trace levels around 0.0001–0.05% as a label claim/soothing support ingredient within broader botanical blends. Dedicated “cica” serums/ampoules and sensitive-skin creams commonly formulate Centella leaf extract in the ~0.1–2% range, while some consumer-available high-strength soothing gels/ampoules list Centella asiatica leaf extract at 5–10% (distinct from higher-percentage ‘Centella water’ or whole-plant extracts). Rinse-off products typically sit toward the lower end due to dilution on use, but the same upper limits can appear on label in specialty leave-on formats when stability/preservative systems are well designed.
