University of Kent News Centre Science Forensic analysis of lipstick trace Forensic analysis of lipstick trace By Karen Baxter 8 August Forensic scientists find a new way of identifying brands of lipstick at a crime scene without removing evidence from its bag.

Using a technique called Raman spectroscopy, which detects laser light, forensic investigators will be able to analyse lipstick marks left at a crime scene, such as on glasses, a tissue, or cigarette butts, without compromising the continuity of evidence as the sample will remain isolated.


Analysis of lipstick traces from crime scenes can be used to establish physical contact between two individuals, such as a victim and a suspect, or to place an individual at a crime scene. The new technique is particularly significant for forensic science as current analysis of lipstick traces relies on destructive forensic techniques or human opinion.

This light is collected using a microscope to give a Raman spectrum which gives a characteristic vibrational fingerprint which can be compared to spectra of lipsticks of various types and brands.

Hence it is possible to determine identity of the lipstick involved. Went and Stuart J.
