Peptides occur naturally in the body. Like proteins, peptides are composed of amino acids. All peptides influence or direct the cells of the body in some way and different types of peptides influence different types of cells. The peptides used in skin care are the ones that communicate with and direct the skin cells to behave in a certain way, such as producing more collagen. Skin care with peptides is reported to reduce the signs of aging by increasing collagen production, thereby making the skin thicker and reducing the appearance of wrinkles. With so many different anti-aging products available it is important to understand what exactly is in the product. Peptides are just part of the ingredients but companies may also use fillers which are chemicals. It is best to find a product that has a high percentage of peptides. So, what exactly is a high percentage of peptides? One company boasts of their product,”Dramatic results—30 percent peptide formulation will work to reduce the visibility of lines and wrinkles. Most users see improvement in skin in just 15 to 30 days.” This happens to be a product that was found to have the highest percentage of peptides compared to many other products. However, RSF Pharmaceuticals has the highest percentage overall, with products containing 50 percent peptides and absolutely no fillers.  Hopefully this information will encourage you to start really reading the labels on the anti-aging products that you are interested in, and now you will be more educated on what peptides and fillers are so you can make the best decisions for your skin.
