9 Further data is needed to determine the safety and efficacy of GHK-Cu for wound healing, but limited small trial data and in vitro data thus far is promising

In laboratory and animal studies, GHK-Cu is reported to stimulate collagen and elastin synthesis , support wound healing and angiogenesis , act as an antioxidant and anti-inflammatory , and modulate the expression of genes tied to skin repair and tissue remodeling [3] [4] [5]

But peptides are also a buzzy focus in the skin care world

Outside of these conditions, GHK-Cu is generally well-tolerated, with minor injection site redness as the most common reported reaction

Starting with GHK-Cu alone allows assessment of baseline response before adding complexity and cost

The earliest signal is injection site behavior
