Peptides are short chains of amino acids that act like gentle messengers in skincare, and they have become a favorite for anyone seeking a firmer, smoother look. Peptide skincare appears in serums, eye creams, moisturizers, neck creams, and masks that help skin feel bouncy and look more resilient. Layer them morning and night alongside sunscreen and your favorite hydrators for a complexion that appears supple, lifted, and beautifully youthful.
