CHICAGO, IL – September 16, 2026. PLU Laboratories, a Chicago-based cosmetics brand and the maker of copper peptide face and hair products, today announced its mission to become the most transparent cosmetics company in the world. The company has published third-party laboratory reports for all three products in its lineup.
Rather than listing actives inside a proprietary blend, PLU Laboratories states the percentage of each one, including the 1% GHK-Cu in its face and hair tonics, and publishes the independent laboratory report that verifies that percentage in the finished product. The reports are published in full at https://plulaboratories.com/pages/lab-test-results.
“I came from the food industry, where consumers began to demand fewer, cleaner ingredients in their food,” said Rob DeSio, Co-Founder of PLU Laboratories. “We believe the same shift is coming to personal care. We could not find simple, transparent products, so we built them. We want to keep making products that are as simple and transparent as we can, for people who care as much about what goes on their body as what goes in it.”
The company’s full mission statement, including what becoming the most transparent cosmetics company in the world means in practice, is published at https://plulaboratories.com/pages/about-us
