Centella Asiatica Stem Cell Exosomes are a high-end skincare ingredient developed by Longzang Biotech in collaboration with the Institute of Botany, Chinese Academy of Sciences (CAS). They are rich in small RNAs, active proteins, and repair factors, enabling targeted anti‑inflammation, soothing and redness reduction, skin barrier strengthening, and accelerated wound healing.

Validated by multi-omics technologies, this ingredient demonstrates significant reparative effects on sensitive skin, acne-prone skin, and post-procedure skin (e.g., after cosmetic dermatological treatments). It stimulates collagen production, improves roughness and redness, while being gentle, non‑irritating, and free from animal‑derived risks. Suitable for both cosmetic (cosmetic‑grade) and medical device (medical‑grade) product registrations, it is widely used in repair serums, healing gels, medical dressings, and professional aesthetic care formulations. It serves as a core ingredient for high‑end functional skincare.
