There are 28 different kinds of collagen, which are further subdivided into eight subfamilies. The majority of collagen types are members of the fibril-forming or fibrillar subfamily. This group includes collagen types I and III, which make up the majority of the extracellular matrix in the dermal layer of skin. Fibrillar collagens of types I, II, and III are also the most frequent.Collagen type I is one of several collagen varieties found in the human body, each with its own distinct structural and functional properties. The numerous types of collagen play crucial roles in maintaining the structure and function of diverse tissues and organs throughout the body.
Type I collagen is the most abundant variety of collagen in the human body and is an essential component of numerous connective tissues, including the skin, bones, tendons, ligaments, and corneas. It is a fibrous protein that gives these tissues strength and structural integrity. Both collagen types I and III are required for wound healing and tissue regeneration; collagen type III is essential in the early stages, whereas collagen type I is highly generated during the late stages.
Type II collagen is a fibrillar collagen that serves as the major component of cartilage, providing tensile strength to the tissue. Collagen type II has been applied as a biomaterial in the regeneration of bone or cartilage tissue, but its effect on skin wound healing is less widely recognized.
Type III collagen is a dominant role in the maturation of collagen type I, producing thin, less durable fibers with faster turnover, yet it is less stable than collagen type I. In mammals, reticular fibers composed of collagen type III are commonly detected alongside collagen type I.
Collagen is an important component in wound care products because it promotes wound healing and tissue regeneration. Type I collagen, the most abundant kind of collagen in the human body, is vital for the structural integrity of skin and connective tissues and is commonly found in various collagen wound care products.
