Palmitoyl Pentapeptide-4 — The Complete History

The Crisis

The Recognition

A lifetime of work finally honored

Key Moment

Karl Lintner awarded the Lifetime Achievement Award by in-cosmetics in Paris for pioneering cosmetic peptides

By 2006, something important happened. Sederma officially renamed their peptide from Palmitoyl Pentapeptide-3 to Palmitoyl Pentapeptide-4 to reflect new research and improved naming standards. Karl and Claire continued their work, publishing more studies with different populations. They tested Matrixyl on different skin types and ages. Everywhere, the results held up. The peptide worked. Scientists around the world started studying it. Universities ran their own tests. Independent researchers confirmed the findings. Matrixyl became the peptide that other peptides were compared against. It set the standard. Then on April 16, 2013, something special happened. The in-cosmetics conference in Paris held their annual awards. They gave Karl Lintner the Lifetime Achievement Award. In front of hundreds of scientists and industry leaders, they honored him as the father of Matrixyl and the pioneer of cosmetic peptides. Karl was in his seventies by then, but he still worked with passion. He knew that his creation had improved millions of lives. Women who thought their wrinkles were permanent found they could fade them. The dream he had carried through decades of quiet research had become real and lasting.
