Identification of lipstick smears by fluorescence observation and purge-and-trap gas chromatography

A Study on Lip Print Pattern, Abo Blood Group and Their Correlation in the Population of Western Up Belt

“…(22) Lipstick smears can lead to an indirect proof of a relationship or contact between victim and a suspect or a suspect and a crime scene. (23) The use of lip prints as a means of personal identification and crime detection device was recommended for the first time in 1932 by Edmond Locard. (24) A detailed study on the measurement of lips, use and colour of elevation, method of mapping the pattern and its subsequent use in forensic application was given by Suzuki in 1967.…”

New Insights of Cheiloscopy

“…[31][32][33] All lip prints are important, even the ones that are not visible. [31,34] Lip prints can be recorded in a number of ways.If located on anon-porous surface, lip prints can be photographed and enlarged.…”

“…[35,36] Lip prints can be made using several substances, such as aluminium powder, silver metallic powder, silver nitrate powder, plumb carbonate powder, fat black aniline dyer or cobalt oxide. [33,37,38] All lip prints contain lipids which make their development possible by using lysochromes dyes (Sudan III, Oil Red O, Sudan Black). Plumb carbonate is a white powder which can be used as a developer with a brush, over smooth, polished, metallic or plastic surfaces.…”

Trace metal analysis by laser ablation-inductively coupled plasmamass spectrometry and x-ray K-edge densitometry of forensic samples

“…Lipstick is worn regularly by many people, smears left on cigarette butts, glassware, clothing, bedding, napkins, paper, etc. may be valuable evidence in a forensic investigation (49,50). Lipstick recovered from clothing or skin may also indicate physical contact between individuals.…”
