As the skin ages, it gradually loses firmness and the ability to "snap back" after being stretched. This leads to sagging, wrinkles, and an overall tired appearance. While many ingredients promise to reverse this process, one compound stands out for its deep scientific backing—GHK-Cu, a copper-binding peptide with remarkable regenerative properties.
Let’s explore how GHK-Cu works to firm loose skin and improve elasticity, supported by decades of clinical research and dermatological studies.
What Is GHK-Cu?
GHK-Cu stands for glycyl-L-histidyl-L-lysine copper peptide complex, a naturally occurring peptide that binds copper ions and plays a critical role in tissue regeneration, wound healing, and anti-inflammatory activity.
Discovered in human plasma in the 1970s, this peptide becomes less abundant with age—right around the time many visible signs of skin aging begin to show.
