Delivering the Science of Skin Health.

Innovatively. Globally.

Clinical Proof: Real Science. Proven Results

Clinical research has demonstrated that copper and DNA repair play fundamental roles in skin health. By prompting the skin’s ability to self-correct, copper is a powerful collagen and elastin promoter and plays an antioxidative role in the body, increasing the benefits of natural tissue building processes. The role of DNA repair enzymes for intense reparation and protection has been documented in multiple clinical studies, proving that the consequences of UV-induced damage can be significantly reduced.
