Peptides are short chains of amino acids that act as building blocks for collagen, elastin, and keratin - the proteins that keep your skin firm, smooth, and youthful. In skincare, peptides help stimulate collagen production, improve elasticity, and strengthen the skin barrier, making them ideal for reducing fine lines, boosting firmness, and enhancing overall resilience. They also support repair and hydration, helping the skin look plumper, healthier, and more lifted over time. Gentle yet powerful, peptides are suitable for all skin types and pair well with most active ingredients, making them a staple in modern anti-aging routines.
