What are peptides in skincare? A plain-language map
Peptides are short chains of amino acids. In skincare they’re used as actives (or supporting ingredients) positioned for firmness appearance, texture, and expression-line look — always as cosmetics, never as drugs.
Search demand for head terms like peptides / peptides for skin is massive; most pages either overclaim or stay too vague. Here’s the map we use at Daily Peptide.
