Collagen is the most abundant protein in the skin, providing structure, firmness, and elasticity. In K-Beauty, collagen is a popular ingredient in serums, creams, masks, and supplements, valued for its ability to improve skin hydration and enhance the appearance of plump, smooth, and youthful-looking skin. While topical collagen primarily helps to moisturise and support the skin's surface rather than replace lost collagen, it is often combined with ingredients such as peptides, hyaluronic acid, and vitamin C to help maintain a healthy skin barrier and promote the radiant, dewy complexion that K-Beauty is renowned for.
