More about the developing of invisible lipstick-contaminated lipmarks on human skin: the usefulness of fluorescent dyes.
At the present time fingerprints are one of the simplest, and most reliable means of identification. Increasingly, crime scene investigators look for palm, foot, ear or lip prints. With regard to lip prints, the use, very common today, of protective or permanent lipsticks allow the production an invisible lipmark (or invisible lipstick-contaminated lipmark) which is possible to develop. Some results have already been published about developers useful for different kinds of surfaces (both porous and non-porous) as well as those which are more efficient in case of old or recent prints. The latest studies are about the developing on human skin, and they prove the usefulness of lysochromes (specifically Sudan Black) for the develop of recent invisible lipstick-contaminated lipmarks on corpse skin. This study attempts to determine the efficiency of fluorescent reagents to develop invisible lipstick-contaminated lipmark on human skin. Results show that REDescent Fluorescent Latent Prints Powder is effective for obtaining recent invisible lipstick-contaminated lip mark on the skin of deceased.
