Peptides for Skin: How They Work Plus the 15 Best Peptide Skincare Products to Try Rn
Peptides are made of amino acid chains, the building blocks of protein in our skin, says plastic surgeon Melissa Doft, MD. “These peptides signal your skin to enter repair mode and produce more collagen and elastin—two proteins responsible for keeping skin smooth and firm.” When your skin has more collagen elastin, you’ll see fewer fine lines and wrinkles, smaller looking pores, and a more lifted and contoured appearance. Some peptides also have anti-inflammatory benefits, so they can help calm skin and reduce sensitivity too.
