Enzovera Recombinant Human Type I Collagen (EV-COL-004) is a 26.9 kDa recombinant human collagen fragment of >90% purity, supplied in sponge form in 50 g and 100 g bags. Type I collagen is the most abundant protein in the human body, constituting the primary structural scaffold of skin, bone, tendon, and connective tissue throughout the musculoskeletal system. EV-COL-004 provides a recombinant, animal-origin-free source of Type I collagen for cosmetic formulation, skin repair products, hemostatic applications, and tissue engineering research — with defined composition, high batch-to-batch consistency, and full traceability absent from animal-extracted collagen preparations.

Biology of Type I collagen. Type I collagen is the dominant fibrillar collagen of the extracellular matrix, assembled from two α1(I) chains and one α2(I) chain wound into a heterotrimeric triple helix approximately 300 nm in length. These trimers self-assemble into fibrils through hierarchical staggered packing arrangements stabilized by covalent cross-links formed by lysyl oxidase, creating the fibers that give skin, tendon, and bone their tensile resilience. In the skin, Type I collagen forms a dense meshwork in the reticular dermis that provides structural integrity and resistance to mechanical deformation. Dermal Type I collagen content declines with age due to reduced fibroblast synthesis and increased matrix metalloproteinase (MMP) activity, causing progressive loss of skin firmness characteristic of intrinsic and photoaged skin — making collagen replenishment a primary target of anti-aging dermocosmetic formulation.

Bioactivity and downstream use. Type I collagen fragments interact with integrin receptors (α1β1, α2β1, α11β1) on fibroblast and keratinocyte surfaces via RGD-containing and GFOGER-related binding motifs, stimulating downstream collagen biosynthesis signaling — the mechanistic basis of pro-collagen induction claimed by topical collagen ingredients. In tissue engineering, Type I collagen hydrogels and sponge scaffolds serve as universal cell culture matrices providing bioinstructive mechanical and adhesive cues matching native soft tissue stiffness, and are enzymatically remodeled by resident cells, enabling dynamic in vitro tissue maturation.
