This small proteoglycan regulates collagen synthesis and organization Glycosaminoglycans Accumulate biphasically in wounds, creating the hydrated environment necessary for proper healing Dermatan Sulfate & Chondroitin Sulfate Production increases, collectively creating the hydrated, resilient matrix characteristic of youthful tissue Metalloproteinase Regulation for Balanced Matrix Turnover GHK-Cu exhibits sophisticated biphasic regulation of matrix metalloproteinases (MMPs) and their inhibitors, creating optimal balance between extracellular matrix synthesis and degradation
