GHK-Cu is a naturally occurring copper-binding peptide complex that plays a fundamental role in tissue repair and remodeling. It is extensively researched in dermatology and wound healing for its potent ability to stimulate the synthesis of critical structural proteins like collagen and elastin. Studies also highlight its anti-inflammatory and antioxidant actions, which help protect skin and other tissues from damage. GHK-Cu's broad support for connective tissue health and skin integrity makes it a cornerstone of both cosmetic and regenerative research.
