Peptides and Growth Factors
A decade ago peptides were one of the buzzwords in skincare. Although other ingredients have overtaken them in popularity now, they still have a value and a place as ingredients. In short, peptides are chains of amino acids, the building blocks of proteins, which act as chemical messengers in the skin. There are many peptides used in skincare with the idea being that they can boost processes such as collagen production. Some of the most popular peptides you may have heard of include: Matrixyl 3000, otherwise known as palmitoyl pentapeptide, copper peptide and Argireline (acetyl hexapeptide-8).
