Peptides and Proteins - The hottest skin care ingredients

What do proteins and peptides have in common? Amino Acids! Peptides are molecules made up of two or more (but less that 50) amino acids bonded together. Longer amino acid chains are called proteins.

Peptides and proteins are present in every living cell and have a very important function when it comes to collagen. As a person ages, environmental exposure and a slowing cell turnover rate leads to an increase in wrinkles and dehydration of the skin.  Collagen is the protein (long amino acid chain) that keeps our skin tight and wrinkle free. When our collagen starts to break down, that's when a peptide's role becomes significantly more important.

Remember collagen is a protein consisting of a long amino acid chain? Well, when it breaks down it breaks into smaller peptide chains. This action of breaking chains sends a signal to the skin that collagen is breaking down and encourages it to produce more collagen.  Applying these small chains of peptides to the skin through topical skin care products can also instigate that all important signal. In effect, the topical peptides are replicating the signal process to urge the skin to produce more collagen - making peptides a very important ingredient for top performance.

One such ingredient available in today’s clinical skincare products is Matrixyl, a palmitoyl pentapeptide that is a signal peptide for collagen production. In fact, Matrixyl can nearly double the amount of the protein collagen needed to give skin its elasticity! Supplementing the skin with this and other topically applied peptides supports the process that makes the skin look and act younger than it is, resulting in firmer more elastic skin –now that’s hot!
