Centella Asiatica Extract

Centella asiatica extract is primarily a soothing/anti-inflammatory botanical (often used around ~0.1–5% in leave-on products) and is generally well tolerated, including in compromised skin when the formula is otherwise simple. However, as a complex plant extract it can still trigger irritation or allergic contact dermatitis in a small subset of highly reactive or eczema-prone patients, especially with higher extract loads or impurity/solvent residues. Given this low-but-real sensitization potential, it scores as gentle rather than very gentle or inert. Safety Notes: Across mass-market and dermocosmetic products, Centella asiatica extract is often included at very low levels (around 0.01–0.1%) primarily for marketing/soothing claims, especially in rinse-off cleansers and lower-cost lotions. Most leave-on toners/serums/creams commonly sit in the ~0.1–5% range, while high-strength consumer “cica” ampoules and concentrated soothing gels frequently disclose 10–25% Centella extract (noting this is typically a supplier extract solution rather than purified actives like madecassoside). Centella extracts are not specifically concentration-limited by major cosmetic regulations, so the upper end is mostly set by stability, sensory impact, and supplier solvent system rather than legal caps.
