KPV acts directly on MC1R/MC4R receptors on macrophages and epithelial cells, reducing IL-6 and TNF- at the transcription level [7,8]
The data isn't bulletproof (preparation methods vary, study quality is uneven), but it's further along than BPC-157's primarily animal evidence base
It is commonly examined in tissue integrity studies, gastrointestinal simulations, vascular signaling experiments, inflammatory pathway research, and exploratory neurological models
It also modulates matrix metalloproteinases (MMPs) and their inhibitors (TIMPs), which helps clear damaged proteins and prevent excessive breakdown of the extracellular matrix
That puts GHK-Cu far above this skincare protocols range
It may shorten downtime after procedures
