It occurs naturally in the body, and its level declines with age \u2014 a fact that has made it a focus of interest in research on regeneration and anti-aging.<\/p>\n<h2>What does the research examine?<\/h2>\n<p>Studies have examined GHK-Cu in the context of collagen production, tissue healing, and the balance of substances in skin tissue. Because of its connection to copper \u2014 an important element in many biological processes \u2014 it has also been studied in contexts of cellular \"signaling\".<\/p>\n<h2>Why is it popular in the skin field?<\/h2>\n<p>The combination of a small, stable peptide with copper has made it widely studied in the cosmetic-research field. That said, as always \u2014 there is a difference between laboratory findings and conclusions, and the compound is for research use only.<\/p>\n<h2>Frequently asked questions<\/h2>\n<p><strong>Why copper specifically?<\/strong><br \/>The copper is part of the molecule and of its studied activity \u2014 not an incidental addition.<\/p>\n<p><strong>How is it reconstituted?<\/strong><br \/>From powder, using <a href=\"\/en\/product\/bac-water\/\">bacteriostatic water<\/a> and<a href=\"\/en\/calculator\/\">our dilution calculator<\/a>.<\/p>\n<p>For the research product details: <a href=\"\/en\/product\/ghk-cu\/\">GHK-Cu<\/a> \u00b7 <a href=\"\/en\/product\/glow\/\">GLOW<\/a>.
