Peptides "Peptides are the individual building blocks that link up to create protein," explains MacGregor. As you recall, collagen is a protein, so, in theory, more peptides equal more collagen. There's no shortage of different types of peptides out there, all of which do have varying degrees of efficacy, MacGregor notes. Still, the nice thing is that they're relatively well-tolerated in almost all skin types, and, unlike retinoids, are safe to use during pregnancy (though of course check with your doctor).
