Centella Asiatica Flower/Leaf/Stem Extract

Centella asiatica extract is primarily a soothing/anti-inflammatory botanical used at low concentrations, and in most clinical and consumer use it is well tolerated on sensitive and eczema-prone skin. However, as a multi-component plant extract (including triterpenes and other phytochemicals), it has a small but real risk of irritant or allergic contact dermatitis in reactive individuals, especially with repeated exposure or in compromised barriers. Given this non-zero sensitization potential despite its calming reputation, it fits best as a generally gentle ingredient rather than exceptionally gentle. Safety Notes: In mass-market leave-on products (creams/lotions/cleansers), Centella Asiatica Flower/Leaf/Stem Extract is often used as a label-level soothing botanical at very low levels (~0.001–0.05%), especially when paired with other extracts. Mid-range serums and barrier creams commonly use ~0.1–5% depending on extract carrier/standardization. High-strength consumer-available “cica/centella” ampoules and mask essences can reach ~10–20% extract solution (often not standardized for asiaticoside/madecassoside and sometimes glycerin/propylene glycol/water-based), with rinse-off products typically sitting lower than leave-on formats due to cost and limited contact time.
