Consumer attention and actual efficacy continue to guide the development of the industry

Cosmetics Business (reported in June 2025) pointed out that GHK-Cu is no longer a one-off trend in the beauty industry, but a "scientifically proven ingredient".

The FlyChem blog (one month ago) cited clinical measurements showing that after 12 weeks of GHK-Cu use, skin elasticity increased by approximately 70% (measured using the Cutometer tool), indicating that it can indeed significantly improve skin firmness and resilience
