Abstract

The purpose of this experiment was to determine which of four acne wash brands will eliminate the most facial E. coli in a week. The 4 different acne wash brands tested during this experiment were: Neutragena, CeraVe, Proactive, and Dermalogica; also included was a control test with sterile water. The hypothesis states, "If 4 acne face wash brands are tested, then ProActive will eliminate the most E. coli." In each trial, E. coli bacteria was spread over petri dishes and was put in the incubator for around 60 hours. Each petri dish was then dotted with sterile paper disks soaked in the acne wash. After completing 15 trials, a descriptive statistical analysis was taken for that data. The descriptive statistical tests suggested that the Dermalogica acne wash was most effective at removing E. coli from agar. In conclusion, the Dermalogica acne wash had the most positive effect, therefore having the highest average removal of E. coli for each test .
