Collagen, as a polymer biomaterial, has been widely studied due to its abundant presence in the extracellular matrix and its key structural functions. In the field of tissue engineering and regenerative medicine, collagen is favored for its good biocompatibility, low immunogenicity and excellent cell adhesion properties. The application of collagen in medical aesthetics, especially as a dermal filler and part of anti-aging treatment, has been a focus of continuous attention in medical research and clinical practice. BOC Sciences offers a full range of collagen, including animal-derived collagen, human-derived collagen, and recombinant collagen. We are committed to expanding chemical-grade or food-grade collagen to injectable grade. In addition, we also provide collagen gel preparation, cell/animal testing, and formulation raw material support services.
Collagen is a natural biopolymer produced in animal fibroblasts, accounting for more than 30% of the total body protein, equivalent to 6% of human body weight. It is a spiral fibrous protein twisted from three peptide chains, mainly synthesized by fibroblasts, with a quaternary structure from amino acids to peptide chains, triple helices to collagen fibers, and is widely distributed in the connective tissues of the human body, such as skin, cartilage and bone, tendons, ligaments, etc. Structurally, collagen molecules exist in the extracellular matrix as supramolecular structures, supporting organs and protecting the body. They play an important role in cell regeneration and ensuring the normal function of skin and bones. Collagen is also closely related to animal cell differentiation and cell aging. At present, at least 30 types of collagen have been discovered, named with Roman numerals in the order of discovery, such as type I, II, and III. The skin is mainly composed of type I and type III collagen, of which type I accounts for 80%-85% and type III accounts for 10%-15%.
Simply put, the working principle of collagen is to inject collagen into the dermis and subcutaneous surface to fill and restore sunken skin. The injected collagen fuses with autologous collagen, activates and repairs broken fibroblasts to achieve collagen proliferation, which can stimulate the production of a large amount of collagen, elastic fibers, and colloids, activate and repair broken fibroblasts, and thus help the skin to be rejuvenated.

Collagen is an important protein in the human body, accounting for approximately 30% of the total protein content. It plays a vital role in maintaining and supporting the structural integrity of various tissues and systems. Collagen is primarily a key component of connective tissue, providing strength, elasticity, and toughness to bones, skin, muscles, tendons, and ligaments. In addition, collagen plays a key role in wound healing and tissue repair. It acts as a scaffold for new tissue growth and is involved in the process of closing wounds and repairing damaged skin and other tissues. In addition to its direct physiological effects, collagen has medical and cosmetic uses. Topical treatments containing collagen are widely used to reduce visible signs of aging and improve skin texture.
Yes, collagen is a protein and is the most abundant protein in the human body, making up about one-third of the body's protein composition. Collagen is composed of the amino acids glycine, proline, and hydroxyproline, which are organized into a triple helical structure. This triple helical structure gives collagen its unique tensile strength and ability to withstand stretching forces. As a result, collagen is an essential component of the structure and strength of various tissues, including skin, bones, tendons, ligaments, and cartilage. It plays a vital role in maintaining the integrity and elasticity of these tissues.
