copper peptides

Copper peptides combine the element copper with three amino acids. Copper peptides occur naturally in the body, and is a growing body of research concerning how copper peptides may improve the appearance of multiple signs of aging, but this concerns synthetic, lab-engineered peptides.

Are copper peptides finally the anti-aging answer? No. Although there’s some convincing research demonstrating copper bound with peptides has skin-smoothing benefit, those studies were set up and paid for by companies selling the ingredient complex or selling products that contain it, typically marketed as GHK-copper.

What’s more, these studies rarely, if ever, compare the allegedly wonderful results of copper peptides other, more established ingredients.
