Cheiloscopic examinations have long been conducted, and many scientists have reported the usefulness of cheiloscopy for personal identification with a characteristic and individual pattern of furrows on the vermilion lip. For almost 40 years, research conducted in Poland has determined the patterns of these furrows and the separation and development of their individual features. This was the basis for forming expert opinions and presenting them in court as evidence. In Poland, cheiloscopic expertise is performed and the results of precise procedures that are accredited and assessed serve as evidence. Although the legal system in Poland (continental system) is completely different from the American system, cheiloscopic expertise was also assessed in detail according to the American standards of evidence. This narrative review presents the problem of cheiloscopic expertise as a scientific and practical issue and provides a brief historical overview of this field and the foundations of the Polish cheiloscopic identification method. We conclude that Poland has sufficient historical background and a robust development of cheiloscopy in the field on a scientific and legal basis; however, due to its reports being in the Polish language, its absence from the most relevant specialized literature, or simply a lack of cooperation between countries and experts, the country has unfairly been left out of the discussion. We believe that a new look at the Polish contribution to lip print identification is necessary to reinsert this topic into the current discussion of a new identification paradigm.
