1.The hyaluronic acid macromolecule forms straight lines—hyaluronan chains.
2.The crosslink agent BDDE will develop hyaluronan chains into reticular formation.
3.Using advanced technology, reticular formation molecule become three-dimensitional matrix,which will improve both viscosity and elasticity of the gel.
4.After injected, the HA filler locks water and expands instantly. Then the soft tissue depression is filled.
