Cross-linked sodium hyaluronate gel (medical use, long-lasting filler)
Superficial/Middle/Deep/Ultra-Deep Series BDDE Cross-Linked Hyaluronic Acid Gel (High Elasticity, Long-Lasting Type)
Achieving long-term sustainability and high-precision molding: Medical-grade multi-crosslinked hyaluronic acid gel.
This product is a cross-linked sodium hyaluronate gel manufactured using a multi-crosslinking technology with BDDE. The degree of crosslinking is precisely controlled within the range of 6-8%, forming a uniform three-dimensional mesh structure that achieves excellent viscoelasticity and shape retention. The duration of effect in the body is long-lasting, ranging from 6 to 18 months, ensuring stable volume maintenance and tissue compatibility. Additionally, the residual crosslinking agent (BDDE) is extremely low (<1 μg/ml), designed with safety in mind. With a lineup tailored for various applications from superficial to ultra-deep layers, it can meet diverse needs in the medical aesthetics field, such as wrinkle improvement, contouring, and volume filling. Furthermore, it is also being developed for medical applications such as joint use and adhesion prevention materials.
