WEBVTT 00:00:02.208 --> 00:00:07.828 G H K copper opens our skin, hair, and pigmentation collection. 00:00:09.048 --> 00:00:10.543 In 1973, 00:00:10.568 --> 00:00:15.448 Loren Pickart and Michael Thaler reported a peptide from human blood serum. 00:00:16.488 --> 00:00:18.908 Its origins lie at the University of California, 00:00:19.268 --> 00:00:21.588 San Francisco, in the United States. 00:00:22.588 --> 00:00:24.848 That is more than fifty years of research history. 00:00:25.968 --> 00:00:27.223 By 1988, 00:00:27.248 --> 00:00:31.468 scientists were studying its copper complex in collagen-producing cells. 00:00:32.308 --> 00:00:38.408 G H K contains three amino acids: glycine, histidine, and lysine. 00:00:39.028 --> 00:00:40.228 It binds copper. 00:00:40.968 --> 00:00:42.688 Collagen helps give skin structure. 00:00:43.528 --> 00:00:46.723 Laboratory studies found increased collagen production, but 00:00:46.748 --> 00:00:50.808 cells in a dish cannot show how well a skin treatment works in people. 00:00:51.648 --> 00:00:54.843 In a randomized study published in 2006, 00:00:54.868 --> 00:00:59.743 13 people completed follow-up after laser resurfacing. 00:00:59.768 --> 00:01:05.668 Copper-peptide skin care showed no clear added benefit for redness or wrinkles, 00:01:05.708 --> 00:01:08.728 although patient satisfaction was higher. 00:01:09.788 --> 00:01:11.483 A small 2026 report 00:01:11.508 --> 00:01:17.243 in 18 people found improved eyebrow hair count and thickness after 12 weeks, 00:01:17.268 --> 00:01:21.008 compared with the opposite eyebrow receiving the comparison serum. 00:01:21.808 --> 00:01:23.208 Both studies were small. 00:01:23.968 --> 00:01:25.843 The FDA flags possible 00:01:25.868 --> 00:01:29.468 immune reactions and impurities with compounded injections. 00:01:30.648 --> 00:01:34.068 Topical findings cannot establish injection safety. 00:01:34.888 --> 00:01:37.308 Its long history is a starting point. 00:01:37.968 --> 00:01:42.468 Judge each claim by the product, the people, and the outcome studied. 00:01:43.288 --> 00:01:44.663 World Peptide Foundation. 00:01:44.688 --> 00:01:47.383 Peptides in 2. 00:01:47.408 --> 00:01:48.928 Every experience matters.
