Abstract

The purpose of this experiment was to determine if there was a difference between the bacterial growth on pig skin with liquid foundation applied and the bacterial growth on pig skin with nothing applied. This is important because people, mostly women, use foundation to complete their daily makeup routines or to cover up blemishes and it can keep acne from healing. The hypothesis of this experiment was the pig skin with foundation applied using the foundation brush applicator would produce more bacterial colonies than the pig skin with foundation applied using sterile swabs and the control experiment. Out of three trials, trial one was a control experiment with no foundation applied to the pig skin. Trial two included the foundation being applied to new pieces of pig skin using sterile cotton swabs. Trial three included the foundation being applied to more pieces of pig skin using a foundation brush. After waiting twenty four hours petri dishes were swabbed with what was on the pig skin. The pictures from the second group of dishes were uploaded to a computer and Imagej software was used to count the number of bacterial colonies in each of them. Data was analyzed in Minitab where an Anova test was run. The results showed there was a significant difference in the amount of bacterial colonies from the foundation coated pig skin and the pig skin alone; therefore, the hypothesis was not supported. Future research could be done by testing different foundations such as powder or cream.
