A new study by forensic scientists at the University of Kent, UK, has established a new method of identifying the brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag. The researchers used a technique called Raman spectroscopy that detects laser light. This technique will allow forensic investigators to analyze lipstick marks left at a crime scene, such as on glasses, a tissue or cigarette butts, without compromising the continuity of evidence because the sample will remain isolated.
