Peptides are basic substances in the human body, which are formed by the dehydration and condensation of multiple amino acids.
In fact, peptides exist naturally in the skin, and the human body can synthesize and degrade peptides according to its physiological state.
Natural peptides come from the enzymatic decomposition products of structural proteins in the epidermis and dermis. They can regulate the cell life cycle and activate aging cells.
According to the molecular weight or the number of amino acids that make up the "peptide", it can be divided into large molecular peptides and small molecular peptides. According to the structure of the peptide chain, it can be divided into "chain peptides" and "cyclic peptides".
In dermatology, the research and application of peptides are also increasingly valued. It has a wide range of applications in anti-aging, anti-inflammatory, moisturizing, whitening and skin repair.
In the market, the most popular are Matrixyl, also known as palmitoyl pentapeptide and Argireline. It has been proven that both have good anti-wrinkle and firming effects. From 2011 to 2018, the proportion of anti-aging cosmetics containing peptides increased from 23.5% to 25.2%, and the number of products containing two or more peptides also increased from 8.2% to 15.5%.
