Peptides

But “peptides” does not describe one ingredient or one universal benefit.

Different peptides have different amino-acid sequences, structures, delivery requirements, and proposed functions. One may support collagen-related signals, another may carry copper, while another may be designed to influence pathways associated with expression lines or skin comfort.

Their value is therefore not found in the number of peptides listed on a package. It comes from selecting an appropriate peptide, keeping it stable, delivering it effectively, and incorporating it into a formula the skin can use consistently.
