Results showed: Significant increase in skin density and thickness Measurable reduction in fine line depth (up to 35% in some cohorts) Improved skin laxity and elasticity scores Enhanced skin moisture retention These effects are largely attributed to GHK-Cus ability to stimulate fibroblast activity the cells responsible for producing collagen type I and III, elastin, and hyaluronic acid
HE and MT (for collagen fiber) staining showed destruction of the normal pancreatic structure, as well as fibrosis in peri-islet-areas (P-IAs) and stromal fibrotic areas (FAs
