Peptides are short chains of 2 or more amino acid residues that are linked by peptide bonds. They come in different lengths, but if the chain contains more than 50 amino acids, this peptide is called a protein.

Collagen, a protein made up of long segments of amino acids, provides a foundation and thickness for our skin. Over time, collagen breaks down, leading to the thinning of the skin and the appearance of wrinkles. In the process of breaking down, shorter segments of amino acids are formed — called peptides. They send a signal to the skin that it has lost collagen and has to start producing it again.

When these peptides are applied in the form of a cream or serum, the skin perceives them as the product of collagen breakdown, which means that the body needs to produce new protein. This helps the cells produce more collagen, which in turn reduces wrinkles and improves skin firmness. However, the effect of peptides is not limited to just this.
