In the rapidly evolving landscape of regenerative aesthetics, CD BioGlyco provides a specialized recombinant type III human collagen production service. While type I collagen is the scaffold of the skin, type III collagen, often referred to as "baby collagen", is the essential fibrillar component responsible for the softness, flexibility, and rapid repair capabilities characteristic of youthful tissue. As human skin ages, the ratio of type III to type I collagen drastically shifts, leading to increased rigidity and decreased healing potential. CD BioGlyco addresses this biological decline by utilizing high-efficiency eukaryotic expression systems to produce 100% human-sequence recombinant type III collagen. Our platform ensures high-purity, bioactive, and non-immunogenic collagen that mimics the natural triple-helix structure, offering a sophisticated solution for high-end cosmetic additives and medical-grade regenerative applications.
Core Technologies
We utilize a proprietary technology suite to ensure the structural integrity and bioactivity of recombinant type III collagen:
High-Yield Eukaryotic Expression
We employ optimized Pichia pastoris and CHO cell lines that secrete full-length human procollagen III with precise post-translational modifications.
Enzymatic Hydroxylation Tuning
Our systems co-express human prolyl 4-hydroxylase (P4H), a critical enzyme that stabilizes the collagen triple helix by hydroxylating specific proline residues.
Triple-Helix Validation
We utilize circular dichroism (CD) and differential scanning calorimetry (DSC) to confirm the presence of the biologically active helical structure, ensuring the protein maintains its shape at physiological temperatures.
Advanced Downstream Processing
Our purification workflow integrates selective precipitation and multi-stage ion-exchange chromatography to achieve pharmaceutical-grade purity while preserving delicate protein folding.
Genomic Optimization
Utilizing advanced bioinformatics, we optimize the human COL3A1 gene sequence for host-specific codon usage, enhancing protein secretion titers and reducing truncated impurities.
Restoring the Biological Architecture of Youth.
The recombinant type III human collagen production service offers an expansive scope designed to serve as the backbone for next-generation skin rejuvenation. Our service goes beyond simple contract manufacturing; we provide a full-spectrum development ecosystem that includes structural tailoring and bio-functional optimization. We specialize in producing recombinant human-sequence collagen that is entirely free from animal-derived pathogens, BSE/TSE risks, and the immunogenic telopeptides often associated with traditional bovine or porcine extractions. Our scope covers the production of high-titer collagen for use in aqueous serums, lipid emulsions, and specialized medical scaffolds.
We provide characterization data with every batch, including structural verification through CD and biological efficacy profiles. Our production capabilities range from milligram-scale research batches to metric-ton industrial supply, ensuring a seamless transition from laboratory development to global market launch. Furthermore, we offer formulation stability studies, helping our clients understand how our type III collagen interacts with other actives like antioxidants or peptides.
Workflow
Chassis Engineering & Vector Design
We design and synthesize a humanized, codon-optimized expression vector containing the full-length gene for human type III collagen. This construct is engineered with strong, inducible promoters and secretion signal sequences, and is then stably transformed into a proprietary high-expression host, such as a glyco-engineered yeast strain or a mammalian cell line (e.g., HEK293), specifically selected and optimized for high-yield secretion of complex proteins.
Precision Fermentation
The production clone is cultured in large-scale, automated bioreactors under tightly controlled conditions. Key parameters, including dissolved oxygen, pH, temperature, and nutrient feed (especially critical precursors like ascorbate), are precisely monitored and adjusted in real-time. This optimizes cell density, viability, and productivity, maximizing the extracellular accumulation of correctly folded, fully hydroxylated procollagen.
Pro-peptide Cleavage
The secreted procollagen is harvested and subjected to a controlled enzymatic digestion process. Using highly specific recombinant peptidases (e.g., ADAMTS-2, BMP-1, or related enzymes), the N- and C-terminal pro-peptide domains are precisely cleaved off. This critical activation step converts the soluble procollagen into mature Type III collagen monomers, which are capable of spontaneous self-assembly into native-like fibrils.
Isocratic Purification
The mature collagen undergoes a multi-step, isocratic purification process. This typically involves a sequence of chromatographic steps, such as affinity capture, ion-exchange, and size-exclusion chromatography, to efficiently remove all process-related impurities, including host cell proteins (HCP), nucleic acids, endotoxins, and any residual pro-peptides. The result is a highly pure, non-immunogenic collagen solution suitable for biomedical applications.
Biophysical Characterization
Every production batch undergoes biophysical and biochemical analysis. This includes SDS-PAGE and mass spectrometry for molecular weight verification, amino acid analysis to confirm sequence fidelity, and CD spectroscopy to demonstrate the correct triple-helical conformation and measure its thermal denaturation temperature (Tm), ensuring it matches the stability profile of native human type III collagen.
Formulation & Lyophilization
The purified collagen solution is concentrated, sterile-filtered, and aseptically dispensed. It is then freeze-dried (lyophilized) under optimized conditions to remove water without damaging the triple-helical structure. The final product is a stable, highly soluble white powder that can be readily reconstituted for integration into advanced cosmetic serums, medical hydrogel scaffolds, or injectable formulations.

Results: This research article by Hu et al. investigates the efficacy of injectable recombinant human collagen type III for ameliorating skin photoaging. The authors conducted a comprehensive evaluation, first confirming the material's favorable injectability, cytocompatibility, and ability to promote fibroblast migration and collagen I/III expression in vitro. In a rat model of UV-induced photoaging, intradermal recombinant human collagen type III injection significantly improved skin metrics (moisture, elasticity, whiteness), increased dermal thickness, and enhanced the density and organization of collagen fibers compared to controls. The study also demonstrated that recombinant human collagen type III possesses immunomodulatory properties, suppressing pro-inflammatory macrophage activity. The findings collectively indicate that recombinant human collagen type III functions not merely as a structural filler but as a bioactive agent that stimulates endogenous collagen regeneration and modulates the skin microenvironment, positioning it as a promising therapeutic candidate for skin rejuvenation.
Applications
Gentle Eye Care Formulations
Its non-irritating, human-identical structure makes recombinant type III collagen exceptionally suitable for the delicate and thin skin of the eye area. It works to reinforce the skin's supportive matrix, helping to visibly reduce the appearance of fine lines, wrinkles, and puffiness while providing lasting hydration to smooth and brighten the periocular region.
Sun Damage Recovery & Repair Lotions
Recombinant type III collagen is specifically incorporated into formulations designed to counteract photoaging. It aids in the structural repair of the dermal-epidermal junction and extracellular matrix that have been degraded by UV exposure, thereby helping to restore skin elasticity, firmness, and deep hydration for a more resilient and youthful complexion.
Professional-Grade Sheet Masks
This ingredient serves as a high-concentration, bioactive core for professional and spa-grade sheet masks. It delivers an immediate, intensive treatment effect, providing deep dermal hydration that results in a visible "plumping" of the skin, a reduction in the appearance of pores, and a lasting, healthy glow.
