Give full play to its excellent biological activity and histocompatibility, promote the proliferation of dermal fibroblasts, improve cell activity, and be absorbed by fibroblasts as raw materials for collagen synthesis, stimulate cells to synthesize more collagen, fill and repair damaged aging skin, rebuild reticular structure, enhance the expansion of damaged skin and restore skin elasticity. Make the skin anti-aging, repair, calm muscles, desensitize, remove scars, eliminate imprints, replenish water and brighten skin color.

Type ⅲ collagen is a homotrimer or protein composed of three identical peptide chains (monomers), and each peptide chain is called α 1 chain of type ⅲ collagen. The formal name of this monomer is collagen III and α- 1 chain, which is encoded by COL3A 1 gene in human body. Type III collagen is a fibrous collagen, and its protein has a long, inflexible triple helix domain.

Distribution of collagen

Collagen is the most important water-insoluble fibrin in extracellular matrix. Collagen types I, II and III are the most abundant and can form similar fiber structures. Type ⅰ collagen often forms coarse fiber bundles, which are widely distributed, mainly in skin, tendons, ligaments and bones, with strong tensile strength, accounting for about 90% of human collagen content;

Type ⅱ collagen mainly exists in cartilage; Type III collagen forms a fine fibril network, which is widely distributed in extensible tissues, such as loose connective tissues such as skin, blood vessels and internal organs. Type ⅳ collagen forms a two-dimensional grid structure, which is the main component and scaffold of basement membrane.
