Copper has been used in skin care for thousands of years. It was heralded as the "fountain of youth" during the ancient Egyptian days. They realized the power of copper before science could prove it worked.
Dr. Lauren Pickart, a biochemist, studied the effects of human aging when he discovered that the main difference between younger blood and older blood was that the healthier “youth' activity found in the former was caused by a small copper-binding peptide called GHK.
“Things change with age, you know?” Pickart said. “Further studies established that GHK-copper improved the healing of skin wounds. As for cosmetic skincare, studies on women in their 50s found that GHK-copper improved skin elasticity, firmness, and thickness while reducing wrinkles, hyperpigmentation, and photo-damage.” It can also be found in copper PCA, to combat inflammation.
Clinical Studies on the Efficacy of Copper Complexes:
There have also been several studies done to assess the efficacy and safety of topically applied copper complexes in women with mild-moderate fine lines and wrinkles in the periocular areas and facial solar lentigenes.
After an 8-week study, all clinical efficacy parameters showed statistically significant improvements over baseline at week 8.
