From serums to moisturizers to eye creams, peptide-infused products are everywhere. But what exactly are peptides, and do they live up to the hype?<\/p>\n<h2>What Are Peptides?<\/h2>\n<p>Peptides are short chains of amino acids, the building blocks of proteins like collagen and elastin in your skin. Think of them as signaling molecules that tell your skin to perform specific functions, like producing more collagen or relaxing muscle contractions that cause wrinkles.<\/p>\n<h2>Types of Peptides<\/h2>\n<p>Signal peptides like palmitoyl pentapeptide-4 (Matrixyl) stimulate collagen production. They&#8217;re the most well-studied and show genuine promise for reducing fine lines. Carrier peptides like copper peptides deliver trace minerals to the skin and support wound healing. Neurotransmitter peptides like acetyl hexapeptide-8 (Argireline) theoretically relax facial muscles similar to Botox, though the effects are much subtler.<\/p>\n<h2>Do They Actually Work?<\/h2>\n<p>The science is promising but not as robust as for retinoids or vitamin C. Some peptide formulations have shown measurable improvements in skin firmness and wrinkle depth in clinical studies. However, peptides are large molecules that may have difficulty penetrating the skin barrier effectively. The formulation matters enormously.<\/p>\n<h2>How to Use Peptides<\/h2>\n<p>Look for peptide serums or moisturizers from reputable brands that have invested in clinical testing. Apply after cleansing and before heavier products. Peptides can be combined with most other ingredients, though some evidence suggests they may be less effective when layered with strong acids. For best results, use consistently for at least 8-12 weeks.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Peptides have become one of the hottest buzzwords in skincare.
