The cosmetic industry is without a doubt one the places where peptides are widely used. But there are different kinds of peptides known to perform specific functions and not all of them are being used in the cosmetic industry. As a matter of fact, the types of peptides used in the cosmetic industry are only four and they include the following-:
Signal peptides are added to skin cosmetics because they have the ability to stimulate skin fibroblasts, which leads to the production of more elastin, collagen, and other proteins within the dermis layer of the skin. Boosting the production of these proteins makes the skin look fuller and firmer and also helps in the elimination of wrinkles, which in turn reverses the effects of aging.
In the cosmetic industry, carrier peptides are used to deliver trace elements such as magnesium and copper which help in wound repair and other enzymatic processes on the skin. It has been proven that the trace elements are vital in improving the elasticity of the skin, pro collagen synthesis and the overall appearance of the skin.
These are the peptides added to cosmetic products to reduce the appearance of wrinkles and reverse the effects of aging because they inhibit the release of acetylcholine by various chemical interactions. Botox is the most extreme neurotransmitter known in the world today and it has been developed to be used on the skin with the hypothesis that it relaxes the muscles on the face, thus leading to smoother and younger face.
Enzyme inhibitor peptides
These peptides operate by reducing the breakdown of collagen and other proteins by interrupting the process of breaking them down. For example, some enzymes have the ability to degrade structural proteins such as collagen and a peptide obtained from rice protein may inhibit the activities of MMP enzyme, thus ensuring that more collagen is available.
