Recombinant Type III Humanized Collagen Lyophilized Fiber is China's first independently developed medical device using a new type of biological material- recombinant humanized collagen. After Recombinant Type III Humanized Collagen Lyophilized Fiber is injected, its triple helix structure forms a collagen fiber network through intermolecular interaction, and the network structure will provide extra support to cells and tissues, so as to physically fill the collapsed part of wrinkles.
