Peptides are short chains of amino acids that serve as the building blocks of proteins such as collagen and elastin, which are essential for maintaining firm, youthful-looking skin. In K-Beauty, peptides are highly valued for their ability to support the skin's natural repair process, improve elasticity, and reduce the appearance of fine lines and wrinkles. Often combined with hydrating and barrier-strengthening ingredients, peptides help promote smoother, plumper, and more resilient skin, making them a key ingredient in achieving the healthy, radiant complexion at the heart of the K-Beauty philosophy.
