Suitability for Different Skin Types Copper peptides gentle nature makes them particularly suitable for: Sensitive skin that cannot tolerate retinoids or acids Rosacea-prone skin requiring anti-aging benefits without inflammation Post-procedure healing when other actives are contraindicated Mature skin where a healthy diet of gentle, effective ingredients is preferred over aggressive treatments The copper switch mechanism, the ability to temporarily alter the skins healing response, makes copper peptides uniquely effective in addressing the complex, multifactorial nature of skin aging while supporting overall skin health and well-being

This mechanism is also the source of cancer-related concerns (more below)

This table makes the distinction painfully clear
