Stimulation of matrix synthesis In fibroblast cultures, GHK-Cu increases the synthesis of the major structural molecules of the extracellular matrix: collagen, elastin, and the glycosaminoglycan/proteoglycan ground substance (including dermatan sulfate and other glycosaminoglycans)
For hair growth specifically, combining topical GHK-Cu with microneedling is supported by the strongest evidence as shown in the 2025 Kuceki study which achieved 26.5% regrowth with this combination approach
