The strongest and oldest evidence for GHK-Cu comes from wound-healing and tissue-repair research it accelerated wound healing and raised antioxidant enzyme levels in animal studies alongside a large body of laboratory work on collagen, the extracellular matrix, and gene expression.213 There are also small, placebo-controlled human studies in which GHK-Cu creams improved skin laxity, reduced the depth of fine lines and wrinkles, and increased skin density.1 That's genuinely encouraging
GLP-1R = appetite suppression
With the advent of advanced clinics in that area, you can now get IV glutathione treatment designed specifically for your skin issues caused by exposure to the sun and air pollution
"Whitening": These terms are often used interchangeably but imply different outcomes
The skin-specific mechanisms of GHK-Cu include stimulation of Type I and Type III procollagen synthesis, increased production of dermatan sulfate and other glycosaminoglycans, activation of the enzyme lysyl oxidase (which cross-links newly formed collagen), reduction of matrix metalloproteinase-1 (MMP-1, collagenase) activity, and anti-inflammatory suppression of TNF-alpha-induced IL-6 secretion
