Research studies have shown that GHK-Cu also smoothens and evens out skin texture:
Topical application of a cream formulated with GHK-Cu resulted in significant smoothing of aged skin, secondary to increased collagen synthesis.
A series of facial studies provide direct evidence that application of GHK-Cu to uninjured skin induces remodeling of the skin, resulting in improved skin appearance, including evened out skin texture.
After 12 weeks of using a facial cream containing GHK-Cu, female participants noted reduction of coarse wrinkles and mottled hyperpigmentation and improved overall appearance.
