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.
