GHK-Cu reduced inflammatory cell infiltration into lung tissue, increased superoxide dismutase activity (bolstering antioxidant defense in the lungs), and decreased both TNF-alpha and IL-6 production
Independent post-2022 replication of those plasma figures remains thin in the published literature
With sugar and sweeteners
They also collected blood samples from the participants to assess levels of 18 cardiovascular disease-related biomarkers
Beyond hydration, GFF has notable antioxidant properties that help protect against oxidative stress and UV-induced inflammation
Matrixyl's mechanism is more targeted: Collagen signaling : The KTTKS sequence mimics a collagen breakdown fragment, signaling fibroblasts that collagen repair is needed Collagen types I and III : Stimulates production of the primary structural collagens in skin Fibronectin production : Enhances production of fibronectin, a key extracellular matrix glycoprotein Palmitoyl enhancement : The lipophilic palmitoyl chain improves skin penetration and receptor binding Mechanistic Comparison# Clinical Evidence Comparison# GHK-Cu Clinical Studies# GHK-Cu has multiple clinical studies supporting its anti-aging effects: Pickart facial study (67-71 women, 12 weeks) : GHK-Cu cream applied twice daily improved skin laxity, clarity, and firmness
