Abstract

Background: Recovering latent fingerprints on human skin is challenging due to its continuous renewal, elasticity, and factors like body temperature and perspiration. Traditional fingerprint powders often fail on skin. This study explores using cosmetic powders to develop latent prints on skin and assess their effectiveness under varying environmental conditions.
Aim: The study employed three cosmetic powders (talcum, eye shadow, and vermilion), a makeup brush, white paper tape, scissors, a glass slide, hand lens, and gloves. Latent fingerprints were intentionally deposited on the forearms and foreheads of 12 individuals of varying ages. These prints were developed with different powders, lifted using tape, and photographed for comparative analysis.
Results: The study assessed talcum, vermilion, and eye shadow powders for latent fingerprint development. Eye shadow powder proved most effective, especially for individuals aged 10-30, yielding clear patterns in over 80% of cases. Vermilion showed promise for younger age groups but less effectiveness for those over 30.
Conclusion: The research evaluated talcum, vermilion, and eye shadow powders for latent fingerprints on living individuals. Eye shadow powder proved most effective, highlighting friction ridges well. Despite limitations, cosmetic powders show potential for forensic use, requiring consideration of skin adherence and hypoallergenic properties in future studies.
