The Essential Role of Collagen in Skin Structure and d Wound Healing

Collagen is mecht abundant protein in thee human body and constitutes about 70- 80% of thee dry weigt of thee skin. It providees tensile equith, structural integraty, and elasticity to thee dermal matrix. There are at least ast 28 known type of kolagen, but in the skin, collagen type I and III dominate, forming a dense network of fibryls that support thee epidermis and anchor blood vessels, nervess, anves, anved cells.

Factors That Influence Collagen 's Healing Capability in Necrobiosis Lipoidica

Glicemic Control

Poor glycemic control is a well-establed risk factor for thee development andd progression of necrobiosis lipoidica. Elevated blood glucose levels directly increase thee formation of AGEs and promote cross- linking of kolagen.

Age andd Duration of Choroby

Both aging and prolonged disease duration are associated with habited collagen production and increaged collagen degradation. Fibroblast senescence leads to reduced synthetic capacity. Older patients may require more aggressive and prolonged treatment to stimulate collagen repair. The density and quality of collagen also decline with age, making thee skin more depeneble.
