Copper Lysinate/Prolinate
Copper lysinate/prolinate is a water-soluble copper complex of the amino acids lysine and proline. Leave-on and rinse-off products use it for skin conditioning and a firmer look, though evidence for routine benefits remains limited.

Our take
Is Copper Lysinate/Prolinate a Good Ingredient?
May support skin conditioning via amino‑acid–bound copper delivery, but human evidence for firming or anti‑aging outcomes is modest. A small risk of irritation exists, particularly for sensitive skin or when used in higher strengths. That mix of modest evidence and some risk keeps it at a Fair rating rather than Good.
What it does
Skin Benefits
May help skin feel more elastic and look refreshed, supporting a firmer appearance. Current evidence in finished products is modest.

Before you use it

Typically well tolerated at low levels, but tingling or transient redness can occur in reactive skin. Introduce gradually and avoid broken skin if you’re prone to irritation.
