Comparisons

AHK-Cu vs GHK-Cu

GHK-Cu has more research — including small human cosmetic studies and an independent wound-healing trial — while AHK-Cu has essentially one laboratory study on hair-follicle cells. Both are copper tripeptides and neither is an approved drug; note that much of GHK-Cu’s cosmetic human data is manufacturer-linked.

On human evidence this is not close: retinoids — especially prescription tretinoin, with retinol as a precursor — have far more controlled human trial data for photoaging than copper peptides, whose cosmetic human evidence is small and largely manufacturer-linked. Copper peptides can be an option for people who can’t tolerate retinoids, but the weight of human evidence belongs to retinoids.

Matrixyl vs Argireline

Matrixyl (Palmitoyl Pentapeptide-4) is a collagen "signal" peptide; Argireline (Acetyl Hexapeptide-8) is a "neurotransmitter-inhibiting" peptide marketed as "Botox in a bottle." Both rest mostly on small or manufacturer-linked cosmetic evidence — and neither is comparable to injected botulinum toxin, which the "Botox in a bottle" tagline implies but the evidence does not support.
