Peptides in skincare fall into four families. Signalling peptides tell cells to make more collagen or elastin. Carrier peptides deliver a trace element to where it is needed. Enzyme-inhibitor peptides quiet an over-active enzyme. Neurotransmitter-inhibitor peptides mimic small neurotoxin behaviour and soften expression lines.
The Peptide Therapy formulation uses a sextet from three of those families, layered so the signalling peptides talk to the collagen machinery while a carrier peptide moves copper into the tissue and a neurotransmitter inhibitor keeps expression territory calm. Six peptides, three actions, one skin.
