Latent lip print test results produced by permanent lipsticks are presented in this work. This cosmetic product, contrary to conventional lipsticks, does not leave visible prints and can thus be overlooked at the crime scene. As print vehicles the study used ceramics, glass, cotton fabric and paper. Lip prints were left to dwell for different periods and were later developed using aluminum powder, cobalt oxide powder and magnetic powder. The results show that identifiable lip prints can be obtained up to 30 days after being produced.
本文展示了永久口红产生的潜在唇印测试结果。与传统口红不同，这种化妆品不会留下可见的印记，因此在犯罪现场可能会被忽视。该研究使用陶瓷、玻璃、棉织物和纸张作为印迹载体。唇印留存不同时长后，再用铝粉、氧化钴粉和磁粉进行显影。结果表明，唇印产生后长达30天仍可获得可识别的唇印。
