The single-phase gel provides strong support and a more three-dimensional effect.

Higher viscoelasticity indicates greater resistance to deformation, displacement, and tissue shear after administration. A pure gel texture without added non-cross-linked hyaluronic acid also provides better support after administration.

100% cross-linked gel provides longer-lasting results.

Through a unique natural cross-linking process, the product's tissue compatibility is effectively enhanced, and long-term retention effectively improves collagen regeneration efficiency. The 100% pure gel texture avoids the rapid metabolism of non-cross-linked components, which can lead to a rapid decline in efficacy, ensuring longer-lasting visual effects.

Extremely low cross-linking residue makes the product safer to inject.

The naturally cross-linked, entangled structure provides inherent support, effectively avoiding the use of excessive cross-linking agents. The purification process developed by Yijiabao's physical and chemical laboratories effectively reduces residual free cross-linking agents.

The double-beveled, ultra-thin-wall stainless steel needle ensures smoother injection.

The uniquely designed double helix pattern matches the syringe, preventing needle dislodgement and providing a more comfortable and easy injection experience for the physician.
