Developed over a decade by the Song-Ji Bio-Tech team, this peptide collagen is engineered to achieve the highest affinity with human skin.
Core Technical Advantages
- Ultra-Small Molecules for Direct Absorption: With a molecular weight of only 1,000 Daltons (approx. 100 nm), it successfully overcomes the skin’s natural absorption barrier (which typically requires molecules to be smaller than 1,500 Daltons). This is an animal-derived peptide that can be absorbed directly by the skin.
- Global Certification: It is officially certified by the INCI (International Nomenclature Cosmetic Ingredient). Currently, it is the only key peptide collagen raw material to hold this certification, allowing for distribution in Japan, Europe, and the United States.
- Pure & Safe Sourcing: Extracted from milkfish scales, the raw material is guaranteed to be free of heavy metals and antibiotics.
- High Biocompatibility: Its superior skin compatibility ensures no allergic reactions, making it the optimal choice for high-end cosmetic formulations.
