Tech Edge: Peptides, Amino Acids and Proteins in Skin Care?

From the column editor: The use of peptides with specific functions has increased significantly in personal care products. One is hard-pressed to find a formula on the shelf that does not list a polypeptide in the ingredient list. How are these peptides made? Where do the sequences originate? This month, I welcome Karl Lintner, PhD, from Sederma/Croda to present basic information on the peptides used in skin care products. Karl Lintner, PhD, is presently a technical advisor to Sederma and Croda Enterprise Technology. He received his degree in chemical engineering and his doctorate degree in biochemistry from Vienna University. From 1973 to 1983, he conducted research in biological peptides at the Nuclear Research Centre in Saclay, France, resulting in the publication of more than 30 papers in biochemistry and biophysics—essentially on peptide activity.
