Common Research Design Considerations Investigators working with copper-binding tripeptides such as AHK-Cu frequently structure studies around in vitro fibroblast or keratinocyte culture models to assess proliferative and gene expression responses, alongside biochemical assays evaluating antioxidant enzyme activity

Lower NAD+ means reduced sirtuin activity (SIRT1, SIRT3), which further impairs mitochondrial function and fatty acid oxidation in fat cells

The culture medium was then replaced with 30 M M-CuP solution, 15 M D-CuP solution, or hydrogel extract at 37 C for another 24 h

Apply a suitable amount on dry face, and gently massage in rolling motions
