Cell source: Minimally invasive extraction of the dermis layer from concealed areas such as the back of the customer's ear/scalp, resulting in better compatibility with their own tissues;
Quality control standard: Compliant with the relevant requirements of the national "Guidelines for Cell Therapy Products", after undergoing quadruple testing (quality/release/review/independent testing), the endotoxin index is controlled at 0.25EU/ml (referring to relevant EU standards, with stricter indicators).                

Persistent effect: Cells can maintain a certain level of activity in the body (the specific duration may vary depending on individual differences and skin conditions, with a clinical observation reference range of 1-3 years), and continue to participate in collagen related processes. The effect may gradually manifest over time and remain stable;
Natural without stiffness: Does not affect the normal movement of facial muscles and ligaments, maintains natural expressions, and avoids the stiffness of 'filling the face'.                

Preparation environment: B+A-level clean GMP laboratory, independent negative pressure operation room, reducing the possibility of sample contamination;
Process control: Digital traceability system, from cell extraction, expansion to cryopreservation, with real-time recording of each step of operation, traceable and traceable;
Culture medium: FDA certified serum-free culture medium is used, which improves safety related indicators by about 86% compared to traditional serum containing culture medium (data from laboratory comparative studies).
