Lip prints have distinct forms of wrinkles and grooves unique to an individual much like fingerprints, footprints, and palm prints. Cheiloscopy, or the study of the grooves and wrinkles on the labial mucosa, helps classify, document, and evaluate lip print patterns. This article utilizes cheiloscopy to analyze students from the San Jose State University population; including 25 participants: 15 females and 10 males of ages between 18-45 years. Print collection utilized a matte lipstick, evenly applied on the lip, to create an impression using tape and white bond paper. Then, using the Suzui and Tsuchihashi method, researchers classified the lip prints. Observations indicate common occurrence of Type III is commonly seen in females (60%), and Type I in males (55%).
