"Copper peptide GHK-Cu." Wikipedia

It is designated solely as a research chemical

Research indicates that: Standard GHK-Cu serums penetrate approximately 0.3 to 0.5 mm into skin Formulations with penetration enhancers may reach 1 to 2 mm depth Concentration at the dermal-epidermal junction is significantly lower than applied concentration Molecular weight (340 Da for GHK-Cu) is borderline for effective dermal penetration Documented Topical Benefits: Studies from the International Journal of Cosmetic Science show topical GHK-Cu application results in: 18 to 30% improvement in skin firmness after 12 weeks Reduction in fine lines and wrinkle depth by approximately 15% Improved skin thickness measurements via ultrasound Enhanced skin barrier function and hydration Reduction in photodamage markers and age spots Optimal Topical Concentrations: Research suggests effective topical concentrations range from 0.05% to 3% GHK-Cu
