Which copper peptide statement is false?
Copper peptides can give products a distinct blue color.
Because copper peptides are under 500 daltons, they readily penetrate the skin.
Copper peptides have less clinical evidence than heavyweights like tretinoin or vitamin C.
The answer is #2.
Being a small molecule doesn't automatically mean an ingredient will readily penetrate your skin. There are still questions around topical copper peptide penetration, stability, and efficacy.
And while copper peptides have been around for roughly 50 years and have an interesting biological story involving things like collagen production and wound healing, that doesn't mean we have decades of robust clinical evidence for them as a topical skincare ingredient.
Interesting science ≠ proven skincare performance.
