🔬 Advanced Recombinant Humanized Collagen Technology
ProtYouth is built on the highest global compliance benchmarks, so our biotech innovations meet clinical standards as well as the world's most demanding cosmetic regulations. Here is the verified research behind the collagen in every formula.
We have been deeply engaged in the structural analysis of recombinant humanized collagen, with 11 atomic-resolution collagen structures successfully submitted to and archived by the Protein Data Bank (PDB), the world's most authoritative database for protein structures. Our type V and type XVII collagen models remain the only entries of their kind currently available in the PDB, underscoring our globally leading position in the study of these collagen subtypes. With robust in-house capabilities in structural elucidation, we are one of the world's most prolific contributors of humanized collagen structural data.
The paper Characterization by high-resolution crystal structure analysis of a triple-helix region of human collagen type III with potent cell adhesion activity, co-authored by core members of our research team, was the first to resolve the high-resolution triple-helical structure of a functional domain of human type III collagen. That study confirmed its exceptional cell adhesion properties, laying the theoretical foundation for next-generation recombinant humanized collagen biomaterials.
The U.S. invention patent US 11,396,537 B recognizes our collagen for the structural design and expression methods of key functional fragments of recombinant collagen, reflecting our work developing functional collagen molecules.
Our research and development in recombinant collagen materials provided critical technical support for the issuance of the National Medical Products Administration's YY/T 1888-2023 Guidelines for Nomenclature of Recombinant Collagen Biomaterials. As the first registered entity (Document No. 001) to complete the filing for recombinant collagen, we pioneered the compliance process in this field. As principal drafter of the first national nomenclature standard and the foremost compliant registrant in the sector, we helped drive the formal classification and regulatory institutionalization of recombinant collagen within China's oversight system.
ProtYouth is powered by Class-A Recombinant Humanized Collagen—a medical-grade biomaterial 100% identical to the human genetic sequence. Unlike animal-derived collagens or recombinant formulas that contain foreign amino acid tags, our molecule carries zero non-human sequences. Free from bovine or marine raw materials, it acts as a true "skin-native" ingredient that your body recognizes as its own.
Co-developed with top scientists and archived in the Protein Data Bank (PDB IDs: 6A0A, 6A0C), our collagen features a proprietary 164.88° flexible triple-helix architecture. This precise 3D geometry forms a self-assembling honeycomb matrix within the skin, exhibiting a cell adhesion rate 250% higher than native collagen. In laboratory models, this high affinity actively guides cell migration up to 97% and prompts fibroblasts to boost endogenous Type I collagen synthesis by 2.65 times.
By restoring dermal scaffolding, cell signaling, and matrix renewal, our molecule delivers clinical-grade structural anti-aging for lasting skin longevity(). Crucially, because it matches your skin's exact biological blueprint, this transformative performance comes with complete peace of mind—delivering deep structural rejuvenation with zero risk of allergic reaction, immunogenicity, or tissue rejection.
Our collagen is not harvested from an animal. It is produced through precision fermentation, a biotechnology process in which the human genetic sequence for type III collagen is expressed and then purified. The result is a protein sequence identical to the type III collagen already present in your own dermis, made without bovine or marine raw material. Our serums contain only collagen and water, produced under ultra-sterile conditions.
Roughly 90% of the global collagen market still relies on marine or bovine sources. Those are heterologous proteins, meaning their sequences are foreign to the human body, so skin may not recognize them well and the benefit can stay at the surface. Because ours carries the same blueprint the skin already uses, it has exceptional skin affinity and is biocompatible, with no risk of rejection. A purified, animal-free protein also means fewer of the extraneous residues that come with animal extraction, which is why our formulas suit skin that reacts easily.
From heart surgery to aesthetic injections, and now into daily skincare, our recombinant humanized collagen brings medical-grade biotechnology into everyday use as a biocompatible, clinically studied material formulated with precision, safety, and care.
