The essential of dermal filler is volume performance for the area needs to be corrected or volumized. Its viscosity and elasticity measured by mechanical method representing its remarkable better volume performance compared with other filler. Through its UHDT(Ultra High Density Technology), it realizes optimal viscoelasticity. The essential of dermal filler is volume performance for the area needs to be corrected or volumized.
