NASHA Technology

NASHA (Non-Animal Stabilized Hyaluronic Acid) technology uses a unique modification and crosslinking process, combined with specialized particle sieving and physical stability optimization, to produce stable gels with different physical properties. It strikes a balance among three key attributes: high safety, strong support, and exceptional comfort.

1, Customized Layered Rejuvenation

We precisely control gel particle size and density based on your specific filling needs — from Derm to Deep, and all the way to Ultra Deep. The result is ultra-fine smoothness for delicate lines, combined with lifting strength and tissue integration. Whether softening crow’s feet or lifting the midface, NASHA delivers.

2, High Viscoelasticity and Stability

By preserving the natural long-chain structure, NASHA gel achieves a higher G’/G” ratio (elasticity to viscosity) at the same crosslinker concentration, offering strong resistance to deformation. Compared to overly crosslinked conventional products, NASHA demonstrates more stable viscoelastic properties both in vitro and in vivo, with slow mechanical degradation during its durability period.

3, Excellent Safety

Adhering to the principle of “low chemical modification,” NASHA retains the natural structure of hyaluronic acid. It features extremely low residual crosslinker and an endotoxin level below 0.04 IU/mg, significantly reducing the risk of post-procedure swelling and foreign body sensation.

4, Smooth and Comfortable Injection Experience

Thanks to a uniform particle distribution, injection force is consistently kept below 25 N. The injection process feels smooth as silk, allowing physicians to precisely control treatment outcomes while significantly reducing pain — offering a comfortable experience even without excessive addition of lidocaine.

HICE Technology

HICE (High Concentration & Uniform Crosslinking Efficiency) technology starts with ultra-high molecular weight hyaluronic acid (HA) and a high-concentration environment, combined with uniform crosslinking. This achieves high crosslinking efficiency with extremely low crosslinker usage, delivering strong lifting capacity and long-lasting results.

1, High Concentration for Strong Support

The technology uses long-chain HA of approximately 3 million Daltons (3 MDa), creating an extremely dense and stable molecular arrangement. This gives the gel stronger elasticity and resistance to displacement — staying firmly in place even in highly expressive facial areas.

2, Uniform Crosslinking for a Dense 3D Network

The unique uniform crosslinking process creates a tight three-dimensional network that effectively resists enzymatic degradation in the body. This means a longer duration of effect, making it an ideal choice for patients seeking long-term aesthetic results.

3, Low Burden, High Purity

Thanks to its exceptionally high crosslinking efficiency, HICE achieves the desired gel hardness with minimal crosslinker usage. While delivering immediate and visible filling results, it allows your skin to enjoy a more natural, low-burden transformation.
