To determine why neuropeptide products are different from other treatments for effective care of skin aging in the market, we must first determine the difference between neuropeptide and amino polypetide ingredients. Neuro-and pentapaptides are peptides but "neuro" refers to very specific functions of this group of peptides, while "penta" merely refers to the size of certain peptide molecules. "Peptide" seems to be the "IT" word in antiaging skin creams today. We have copper peptides, amino acids, polypeptides, Hexapeptide, pentapeptides and now neuropeptides. Others including Dr. Neal Barnard, offer their opinions as well. And then there are all the variants like acetyl hexapeptide-3 and palmitoyl pentapeptide (aka palmitoyl oligopeptide). The list is virtually endless and very confusing to non-biochemist.

I'll try to help them wade through some of the jargon. A peptide is simply a small protein consisting of amino acids. Peptides are active in very small doses, are very specific and have a very good safety profile when used physiologically? that is, to help or change the physical processes of an organism. If we also have some of the above peptide tags, we can begin to discriminate between them. The use of amino-amino acid polypeptide is a bit redundant because all peptides are amino acids. The "poly" just means that this is one of several amino acid peptide. A "hexapeptide is a chain of exactly six (hexa ) amino acids, a pentatpeptide is a chain of five (penta). A chemist working with a palmitoylated five-amino-chain amino acid peptide called "palmitoyl pentapeptide", while another chemical study of the same oligopeptide molecule called "palmitoyl .
