Peptides are short chains of amino acids, which are the building blocks used to form proteins. In skincare, different types of peptides are incorporated into formulations designed to support the appearance and condition of the skin.
Depending on the specific peptides and formulation, peptide serums are often marketed to support smoother, firmer, and healthier-looking skin.
It is important to understand that "peptides" refers to a large group of ingredients rather than one single ingredient. Different peptides can have different properties, and the effectiveness of a product depends on the particular peptide, concentration, formulation, and supporting ingredients.
Peptide serums are generally used as part of a long-term skincare routine rather than as an instant solution for wrinkles or sagging.
